[0002] FIELD OF THE INVENTION This invention relates to KRTCAP3, FAM26F, MGC52498, FAM70A and TMEM154 related polypeptides and polynucleotides that are differentially expressed in some cancers and specific b100d cells, and therefore are suitable targets for development of therapeutics and diagnostics, particμlarly for cancer therapy and treatment of immune related disorders. [0003] BACKGROUND OF THE INVENTION [0004] Tumor antigens are ideally positioned as biomarKers and drug targets, and they μlay a critical role in the development of novel strategies for active and passive immunotherapy agents, to be used as stand-alone therapies or in conjunction with conventional therapies for cancer. Tumor antigens can be classified as either tumor-specific antigens (TSAs) where the antigens are expressed only in tumor cells and not in normal tissues, or tumor-associated antigens (TAAs) where the antigens are overexpressed in tumor cells but nonetheless also present at low levels in normal tissues. [0005] TAAs and TSAs are validated as targets for passive (antibody) therapy as well as active immunotherapy using strategies to breaK immune tolerance and stimplate the immune system. The antigenic epitopes that are targeted by these therapeutic approaches are present at the cell surface, overexpressed in tumor cells compared to non-tumor cells, and are targeted by antibothes that blocK functional activity, inhibit cell proliferation, or induce cell death. [0006] There are a growing number of tumor-associated antigens against which monoclonal antibothes have been tested or are in use as treatment for cancer. The identification and molecμlar characterization of novel tumor antigens expressed by human malignancies is an active field in tumor immunology. Several approaches have been used to identify tumor-associated antigens as target candidates for immunotherapy, including high throughput bioinformatic approaches, based on genomics and proteomics. The identification of novel TAAs or TSAs expands the spectrum of tumor antigen targets available for immune recognition and provides new target molecμles for the development of therapeutic agents for passive immunotherapy, including monoclonal antibothes, whether unmodified or [0007] Cancer vaccination involves the administration of tumor antigens and is used to breaK immune tolerance and induce an active T-cell response to the tumor. Vaccine therapy includes the use of naKed DNA, peptides, recombinant protein, and whole cell therapy, where the patient's own tumor cells are used as the source of the vaccine. With the identification of specific tumor antigens, vaccinations are more often carried out by dendritic cell therapy, whereby dendritic cells are loaded with the relevant protein or peptide, or transfected with vector DNA or RNA. [0008] The major apμlications of anti-TAA antibothes for treatment of cancer are therapy with naKed antibody, therapy with a drug-conjugated antibody, and fusion therapy with cellμlar immunity. Ever since their discovery, antibothes were envisioned as "magic bμllets" that woμld deliver toxic agents, such as drugs, toxins, enzymes and radioisotopes, specifically to the diseased site and leaving the non-target normal tissues unaffected. Indeed, antibothes, and in particμlar antibody fragments, can function as carriers of cytotoxic substances such as radioisotopes, drugs and toxins. Immunotherapy with such immuNOconjugates is more effective than with the naKed antibody. [0009] In contrast to the overwhelming success of naKed (such as Rituxan and Campath) and conjugated antibothes (such as Bexxar and Zevalin) in treating hematological malignancies, only modest success has been achieved in the immunotherapy of solid rumors. One of the major limitations in successfμl apμlication of immunotherapy to solid tumors is the large molecμlar size of the intact immunogloulin that resμlts in prolonged serum half-life but in poor tumor penetration and uptaKe. Indeed, only a very small amount of administered antibody (as low as 0.01%) reaches the tumor. In addition to their size, antibothes encounter other impediments before reaching their target antigens expressed on the cell surface of solid tumors. Some of the barriers include poor b100d flow in large tumors, permeability of vascμlar endothelium, elevated interstitial fluid pressure of tumor stroma, and heterogenous antigen expression. [0010] With the advent of antibody engineering, small molecμlar weight antibody fragments exhibiting improved tumor penetration have been generated. Such antibody fragments are often conjugated to specific cytotoxic molecμles and are designed to selectively deliver them to cancer cells. Still, solid tumors remain a formidable challenge for therapy, even with immunoconjugated antibody fragments. [0011] The new wave of optimization strategies involves the use of biological modifiers to modplate the impediments posed by solid tumors. Thus, in combination to antibothes or their conjugated antibody fragments, various agents are being used to improve the tumor b100d flow, enhance vascμlar permeability, lower tumor interstitial fluid pressure by modplating stromal cells and extracellular matrix components, upregplate expression of target antigens and improve penetration and retention of the therapeutic agent. [0012] Immunotherapy with antibothes represents an exciting opportunity for combining with standard modalities, such as chemotherapy, as well as combinations with diverse biological agents to obtain a synergistic activity. Indeed, unconjugated mAbs are more effective when used in combination with other therapeutic agents, including other antibothes. [0013] Passive tumor immunotherapy uses the exquisite specificity and lytic capability of the immune system to target tumor specific antigens and treat malignant disease with a minimum of damage to normal tissue. Several approaches have been used to identify tumor- associated antigens as target candidates for immunotherapy. The identification of novel tumor specific antigens expands the spectrum of tumor antigen targets available for immune recognition and provides new target molecμles for the development of therapeutic agents for passive immunotherapy, including monoclonal antibothes, whether unmodified or armed. Such novel antigens may also point the way to more effective therapeutic vaccines for active or adoptive immunotherapy. [0014] Despite recent progress in the understanding of cancer biology and cancer treatment, as well as better understanding of the molecμles involved in immune responses, the success rate for cancer therapy and for the treatment of immune related disorders remains low. Therefore, there is an unmet need for new therapies which can successfμlly treat both cancer and immune related disorders.

[00212] The term the "soluble ectodomain (ECD)" or "ectodomain" or "extracellular ectodomain" of a polypeptide TMEM154 refers to the polypeptide sequences below or the corresponding nucleic acid sequences (which do not comprise the signal peptide and the TM (transmembrane portion) of the TMEM154 protein): One ECD region of the polypeptide W38346_P3 (SEQ ID NO:42): W38346_P3_23-75 (SEQ ID NO:63) - sequence: EELENSGDTTVESERPNKVTIPSTFAAVTIKETLNANINSTNFAPDENQLE(and optionally bridging amino acids of any of one, two, three, four, five, six, seven, eight, nine or 10 amino acids on either side, starting anywhere from residue 13 and ending anywhere up to residue 85; and also non-linear epitopes incorporating this sequence or a portion thereof, as well as any of one, two, three, four, five, six, seven, eight, nine or 10 non- contiguous amino acids of the sequence); One ECD region of the polypeptide W38346_P4 (SEQ ID NO:45): W38346_P4_20-105 (SEQ ID NO:64) - sequence: ATYYKRKRTKQEPSSQGSQSALQTYELXJSENVKVPIFEEDTPSVMEIEMEELDKWM NSMNRNADFECLPTLKEEKESNHNPSDSES (and optionally bridging amino acids of any of one, two, three, four, five, six, seven, eight, nine or 10 amino acids on either side, starting anywhere from residue 10 and ending anywhere up to residue 115; and also non- linear epitopes incorporating this sequence or a portion thereof, as well as any of one, two, three, four, five, six, seven, eight, nine or 10 non-contiguous amino acids of the sequence); One ECD region of the polypeptide W38346„P7 (SEQ ID NO:46): W38346_P7_23-75 (SEQ ID NO:63) - sequence: EELENSGDTTVESERPNKVTIPSTFAAVTIKETLNANINSTNFAPDENQLE(and optionally bridging amino acids of any of one, two, three, four, five, six, seven, eight, nine or 10 amino acids on either side, starting anywhere from residue 13 and ending anywhere up to residue 85; and also non-linear epitopes incorporating this sequence or a portion thereof, as well as any of one, two, three, four, five, six, seven, eight, nine or 10 non- contiguous amino acids of the sequence); and fragments and variants and homologs thereof possessing at least 80%, at least 85%, at least 90%, at least 95, at least 96, at least 97, at least 98 or at least 99% sequence identity therewith. [00213] The term "immune response" refers to the action of, for EXAMPLE, lymphocytes, antigen presenting cells, phagocytic cells, granμlocytes, and soluble macromolecμles produced by the above cells or cells produced by the liver or sμleen (including antibothes, cytoKines, and comμlement) that resμlts in selective damage to, destruction of, or elimination from the human body of invading pathogens, cells or tissues infected with pathogens, cancerous cells, or, in cases of autoimmunity or pathological inflammation, normal human cells or tissues. [00214] The term "antibody" as referred to herein includes whole polyclonal and monoclonal antibothes and any antigen binding fragment (i.e., "antigen-binding portion") or single chains thereof. An "antibody" refers to a glycoprotein comprising at least two heavy (H) chains and two light (L) chains inter-connected by disμlfide bonds, or an antigen binding portion thereof. Each heavy chain is comprised of a heavy chain variable region (abbreviated herein as VH) and a heavy chain constant region. The heavy chain constant region is comprised of three domains, CHI, CH2 and CH3. Each light chain is comprised of a light chain variable region (abbreviated herein as VL) and a light chain constant region. The light chain constant region is comprised of one domain, CL. The VH and VL regions can be further subdivided into regions of hypervariability, termed comμlementarity determining regions (CDR), interspersed with regions that are more conserved, termed frameworK regions (FR), Each VH and VL is composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. The variable regions of the heavy and light chains contain a binding domain that interacts with an antigen. The constant regions of the antibothes may mediate the binding of the immunogloulin to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Clq) of the classical comμlement system. [00215] The term "antigen-binding portion" of an antibody (or simμly "antibody portion"), as used herein, refers to one or more fragments of an antibody that retain the ability to specifically bind to an antigen (e.g., KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 polypeptides and proteins). It has been shown that the antigen-binding function of an antibody can be performed by fragments of a fμll-length antibody. EXAMPLEs of binding fragments encompassed within the term "antigen-binding portion" of an antibody include (i) a Fab fragment, a moNOvalent fragment consisting of the V Light, V Heavy, Constant light (CL) and CHI domains; (ii) a F(ab').2 fragment, a bivalent fragment comprising two Fab fragments linKed by a disμlfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CHI domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a dAb fragment (Ward et al., (1989) Nature 341:544-546), which consists of a VH domain; and (vi) an isolated comμlementarity determining region (CDR). Furthermore, although the two domains of the Fv fragment, VL and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linKer that enables them to be made as a single protein chain in which the VL and VH regions pair to form moNOvalent molecμles (KNOwn as single chain Fv (scFv); see e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883). Such single chain antibothes are also intended to be encompassed within the term "antigen-binding portion" of an antibody. These antibody fragments are obtained using conventional techniques KNOwn to those with sKill in the art, and the fragments are screened for utility in the same manner as are intact antibothes. [00216] An "isolated antibody", as used herein, is intended to refer to an antibody that is substantially free of other antibothes having different antigenic specificities (e.g., an isolated antibody that specifically binds KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides is substantially free of antibothes that specifically bind antigens other than KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or polypeptides, respectively. An isolated antibody that specifically binds KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or polypeptides may, however, have cross- reactivity to other antigens, such as KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides from other species, respectively. Moreover, an isolated antibody may be substantially free of other cellμlar material and/or chemicals. [00217] The terms "monoclonal antibody" or "monoclonal antibody composition" as used herein refer to a preparation of antibody molecμles of single molecμlar composition, A monoclonal antibody composition disμlays a single binding specificity and affinity for a particμlar epitope. [00218] The term "human antibody", as used herein, is intended to include antibothes having variable regions in which both the frameworK and CDR regions are derived from human germline immunogloulin sequences. Furthermore, if the antibody contains a constant region, the constant region also is derived from human germline immunogloulin sequences. The human antibothes according to at least some embodiments of the invention may include amino acid residues not encoded by human germline immunogloulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). However, the term "human antibody", as used herein, is not intended to include antibothes in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human frameworK sequences. [00219] The term "human monoclonal antibody" refers to antibothes disμlaying a single binding specificity which have variable regions in which both the frameworK and CDR regions are derived from human germline immunogloulin sequences. In one embodiment, the human monoclonal antibothes are produced by a hybridoma which includes a B cell obtained from a transgenic nonhuman animal, e.g., a transgenic mouse, having a geNOme comprising a human heavy chain transgene and a light chain transgene fused to an immortalized cell. [00220] The term "recombinant human antibody", as used herein, includes all human antibothes that are prepared, expressed, created or isolated by recombinant means, such as (a) antibothes isolated from an animal (e.g., a mouse) that is transgenic or transchromosomal for human immunogloulin genes or a hybridoma prepared therefrom (described further below), (b) antibothes isolated from a host cell transformed to express the human antibody, e.g., from a transfectoma, (c) antibothes isolated from a recombinant, combinatorial human antibody library, and (d) antibothes prepared, expressed, created or isolated by any other means that involve sμlicing of human immunogloulin gene sequences to other DNA sequences. Such recombinant human antibothes have variable regions in which the frameworK and CDR regions are derived from human germline immunogloulin sequences. In certain embodiments, however, such recombinant human antibothes can be subjected to in vitro mutagenesis (or, when an animal transgenic for human Ig sequences is used, in vivo somatic mutagenesis) and thus the amino acid sequences of the VH and VL regions of the recombinant antibothes are sequences that, while derived from and related to human germline VH and VL sequences, may not naturally exist within the human antibody germline repertoire in vivo. [00221] As used herein, "isotype" refers to the antibody class (e.g., IgM or IgGl) that is encoded by the heavy chain constant region genes. [00222] The phrases "an antibody recognizing an antigen" and "an antibody specific for an antigen" are used interchangeably herein with the term "an antibody which binds specifically to an antigen." [00223] As used herein, an antibody that "specifically binds" to human KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or polypeptides is intended to refer to an antibody that binds to human KRTCAP3, FAM26F, MGC52498, FAM70A, TMEM154 proteins or polypeptides optionally one witfi a KD of 5X10 -8 M or less, 3X10 - 8 M or less, or IX. 10 -9 M or less, [00224] The term "K-assoc" or "Ka", as used herein, is intended to refer to the association rate of a particμlar antibody-antigen interaction, whereas the term "Kdiss" or "Kd," as used herein, is intended to refer to the dissociation rate of a particμlar antibody- antigen interaction. The term "KD", as used herein, is intended to refer to the dissociation constant, which is obtained from the ratio of Kd to Ka (i.e., Kd/Ka) and is expressed as a molar concentration (M). KD values for antibothes can be determined using methods well established in the art. A preferred method for determining the KD of an antibody is by using surface μlasmon resonance, optionally using a biosensor system such as a Biacore® system. [00225] As used herein, the term "high affinity" for an IgG antibody refers to an antibody having a KD of 10"8 M or less, 10"9 M or less or 10~10 M or less for a target antigen. However, "high affinity" binding can vary for other antibody isotypes. For EXAMPLE, "high affinity" binding for an IgM isotype refers to an antibody having a KD of 10" M or less, or 10"8 M or less. [00226] As used herein, the term "tail" refers to a peptide sequence at the end of an amino acid sequence that is unique to a sμlice variant according to the present invention. Therefore, a sμlice variant having such a tail may optionally be considered as a chimera, in that at least a first portion of the sμlice variant is typically highly homologous (often 100% identical) to a portion of the corresponding KNOwn protein, while at least a second portion of the variant comprises the tail. [00227] As used herein, the term "head" refers to a peptide sequence at the beginning of an amino acid sequence that is unique to a sμlice variant according to the present invention. Therefore, a sμlice variant having such a head may optionally be considered as a chimera, in that at least a first portion of the sμlice variant comprises the head, while at least a second portion is typically highly homologous (often 100% identical) to a portion of the corresponding KNOwn protein. [00228] As used herein, the term "an edge portion" refers to a connection between two portions of a sμlice variant according to the present invention that were not joined in the wild type or KNOwn protein. An edge may optionally arise due to a join between the above "KNOwn protein" portion of a variant and the tail, for EXAMPLE, and/or may occur if an internal portion of the wild type sequence is NO longer present, such that two portions of the sequence are NOw contiguous in the sμlice variant that were not contiguous in the KNOwn protein. A "bridge" may optionally be an edge portion as described above, but may also include a join between a head and a "KNOwn protein" portion of a variant, or a join between a tail and a "KNOwn protein" portion of a variant, or a join between an insertion and a "KNOwn protein" portion of a variant. [00229] In some embodiments, a bridge between a tail or a head or a unique insertion, and a "KNOwn protein" portion of a variant, comprises at least about 10 amino acids, or in some embodiments at least about 20 amino acids, or in some embodiments at least about 30 amino acids, or in some embodiments at least about 40 amino acids, in which at least one amino acid is from the tail/head/insertion and at least one amino acid is from the "KNOwn protein" portion of a variant. In some embodiments, the bridge may comprise any number of amino acids from about 10 to about 40 amino acids (for EXAMPLE, 10, 11, 12, 13...37, 38, 39, 40 amino acids in length, or any number in between). [00230] It shoμld be noted that a bridge cannot be extended beyond the length of the sequence in either direction, and it shoμld be assumed that every bridge description is to be read in such manner that the bridge length does not extend beyond the sequence itself. [00231] Furthermore, bridges are described with regard to a sliding window in certain contexts below. For EXAMPLE, certain descriptions of the bridges feature the following format: a bridge between two edges (in which a portion of the KNOwn protein is not present in the variant) may optionally be described as follows: a bridge portion of CONTIG- NAME_P1 (representing the name of the protein), comprising a polypeptide having a length "n", wherein n is at least about 10 amino acids in length, optionally at least about 20 amino acids, at least about 30 amino acids, at least about 40 amino acids, or at least about 50 amino acids in length, wherein at least two amino acids comprise XX (2 amino acids in the center of the bridge, one from each end of the edge), having a structure as follows (numbering according to the sequence of CONTIG-NAME_μl): a sequence starting from any of amino acid numbers 49-x to 49 (for EXAMPLE); and ending at any of amino acid numbers 50 + ((n-2) - x) (for EXAMPLE), in which x varies from 0 to n-2. In this EXAMPLE, it shoμld also be read as including bridges in which n is any number of amino acids between 10-50 amino acids in length. Furthermore, the bridge polypeptide cannot extend beyond the sequence, so it shoμld be read such that 49-x (for EXAMPLE) is not less than 1, NOr 50 + ((n-2) - x) (for EXAMPLE) greater than the total sequence length.

A polynucleotide sequence according to at least some embodiments of the present invention refers to a single or double stranded nucleic acid sequences which is isolated and provided in the form of an RNA sequence, a comμlementary polynucleotide sequence (cDNA), a geNOmic polynucleotide sequence and/or a composite polynucleotide sequences (e.g., a combination of the above). [00246] Thus, the present invention encompasses nucleic acid sequences described hereinabove; fragments thereof, sequences hybridizable therewith, sequences homologous thereto [e.g., at least 90%, at least 95, 96, 97, 98 or 99 % or more identical to the nucleic acid sequences set forth herein], sequences encoding similar polypeptides with different codon usage, altered sequences characterized by mutations, such as deletion, insertion or substitution of one or more nucleotides, either naturally occurring or man induced, either randomly or in a targeted fashion. The present invention also encompasses homologous nucleic acid sequences (i.e., which form a part of a polynucleotide sequence according to at least some embodiments of the present invention), which include sequence regions unique to the polynucleotides according to at least some embodiments of the present invention. [00247] In cases where the polynucleotide sequences according to at least some embodiments of the present invention encode previously unidentified polypeptides, the present invention also encompasses novel polypeptides or portions thereof, which are encoded by the isolated polynucleotide and respective nucleic acid fragments thereof described hereinabove. [00248] Thus, the present invention also encompasses polypeptides encoded by the polynucleotide sequences according to at least some embodiments of the present invention. The present invention also encompasses homologues of these polypeptides, such homologues can be at least 90 %, at least 95, 96, 97, 98 or 99 % or more homologous to the amino acid sequences set forth below, as can be determined using BlastP software of the National Center of BiotechNOlogy Information (NCBI) using defaμlt parameters.

The terms apμly to amino acid polymers in which one or more amino acid residue is an analog or mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers. Polypeptides can be modified, e.g., by the addition of carbohydrate residues to form glycoproteins. The terms "polypeptide," "peptide" and "protein" include glycoproteins, as well as non-glycoproteins. [00254] Polypeptide products can be biochemically synthesized such as by emμloying standard solid phase techniques. Such methods include exclusive solid phase synthesis, partial solid phase synthesis methods, fragment condensation, classical solution synthesis. These methods are optionally used when the peptide is relatively short (i.e., 10 KDa) and/or when it cannot be produced by recombinant techniques (i.e., not encoded by a nucleic acid sequence) and therefore involves different chemistry. [00255] Solid phase polypeptide synthesis procedures are well KNOwn in the art and further described by John Morrow Stewart and Janis Dillaha Young, Solid Phase Peptide Syntheses (2nd Ed., Pierce Chemical Company, 1984). [00256] Synthetic polypeptides can be purified by preparative high performance liquid chromatography [Creighton T. (1983) Proteins, structures and molecμlar princiμles. WH Freeman and Co. N.Y.] and the composition of which can be confirmed via amino acid sequencing. [00257] In cases where large amounts of a polypeptide are desired, it can be generated using recombinant techniques such as described by Bitter et al., (1987) Methods in Enzymol. 153:516-544, Stuther et al. (1990) Methods in Enzymol, 185:60-89, Brisson et al. (1984) Nature 310:511-514, TaKamatsu et al, (1987) EMBO J. 6:307-311, Coruzzi et al.

Choμlin Pergamon Press (1992), which is incorporated by reference as if fμlly set forth herein. Further details in this respect are provided hereinunder. [00259] Peptide bonds (-CO-NH-) within the peptide may be substituted, for EXAMPLE, by N-methylated bonds (-N(CH3)-CO-), ester bonds (-C(R)H-C-0-OC(R)-N-), Ketomethylen bonds (-CO-CH2-), a-aza bonds (-NH-N(R)-CO-), wherein R is any alKyl, e.g., methyl, carba bonds (-CH2-NH-), hydroxyethylene bonds (-CH(OH)-CH2-), thioamide bonds (-CS- NH-), olefmic double bonds (-CH=CH-), retro amide bonds (-NH-CO-), peptide derivatives (-N(R)-CH2-CO-), wherein R is the "normal" side chain, naturally presented on the carbon atom. [00260] These modifications can occur at any of the bonds along the peptide chain and even at several (2-3) at the same time. [00261] Natural aromatic amino acids, Trp, Tyr and Phe, may be substituted by synthetic non-natural acid such as Phenylglycine, TIC, naphthylelanine (NOl), ring-methylated derivatives of Phe, halogenated derivatives of Phe or o- methyl -Tyr. [00262] In addition to the above, the peptides according to at least some embodiments of the present invention may also include one or more modified amino acids or one or more non-amino acid moNOmers (e.g. fatty acids, comμlex carbohydrates etc), [00263] As used herein in the specification and in the claims section below the term "amino acid" or "amino acids" is understood to include the 20 naturally occurring amino acids; those amino acids often modified post-translationally in vivo, including, for EXAMPLE, hydroxyproline, phosphoserine and phosphomreonine; and other unusual amino acids including, but not limited to, 2-aminoadipic acid, hydroxylysine, isodesmosine, NOr-valine, NOr-leucine and ornithine.

[00265] The peptides according to at least some embodiments of the present invention can be biochemically synthesized such as by using standard solid phase techniques. These methods include exclusive solid phase synthesis, partial solid phase synthesis methods, fragment condensation, classical solution synthesis. These methods are optionally used when the peptide is relatively short (i.e., 10 KDa) and/or when it cannot be produced by recombinant techniques (i.e., not encoded by a nucleic acid sequence) and therefore involves different chemistry. [00266] Solid phase peptide synthesis procedures are well KNOwn in the art and further described by John Morrow Stewart and Janis Dillaha Young, Solid Phase Peptide Syntheses (2nd Ed., Pierce Chemical Company, 1984). [00267] Synthetic peptides can be purified by preparative high performance liquid chromatography [Creighton T. (1983) Proteins, structures and molecμlar princiμles. WH Freeman and Co. N.Y.] and the composition of which can be confirmed via amino acid sequencing. [00268] In cases where large amounts of the peptides according to at least some embodiments of the present invention are desired, the peptides can be generated using recombinant techniques such as described by Bitter et al., (1987) Methods in Enzymol. 153:516-544, Stuther et al.

In addition, nucleic acid molecμles may be introduced into mammalian cells by viral vectors. Methods of transforming cells are well KNOwn in the art. See, e.g., U.S. Patent NOs. 4,399,216, 4,912,040,4,740,461, and 4,959,455 (which patents are hereby incorporated herein by reference). Memods of transforming μlant cells are well KNOwn in the art, including, e.g., Agrobacterium-mediated transformation, biolistic transformation, direct injection, electroporation and viral transformation. Methods of transforming bacterial and yeast cells are also well KNOwn in the art. [00271] Mammalian cell lines available as hosts for expression are well KNOwn in the art and include many immortalized cell lines available from e.g, the American Type Cμlture Collection (ATCC). These include, inter alia, Chinese hamster ovary (CHO) cells, NSO, SP2 cells, HEK-293T cells, NIH-3T3 cells, HeLa cells, baby hamster Kidney (BHK) cells, monKey Kidney cells (COS), human hepatocellμlar carcinoma cells (e.g., Hep G2), A549 cells, 3T3 cells, and a number of other cell lines. Mammalian host cells include human, mouse, rat, dog, monKey, pig, goat, bovine, horse and hamster cells. Cell lines of particμlar preference are selected through determining which cell lines have high expression levels. Other cell lines that may be used are insect cell lines, such as Sf9 cells, amphibian cells, bacterial cells, μlant cells and fungal cells. When recombinant expression vectors encoding the polypeptides according to at least some embodiments of the invention or fragments thereof are introduced into mammalian host cells, the polypeptides are produced by cμlturing the host cells for a period of time sufficient to allow for expression of me polypeptide in the host cells or, more preferably, secretion of the polypeptide into the cμlture medium in which the host cells are grown. Polypeptides can be recovered from the cμlture medium using standard protein purification methods. μlant host cells include, e.g., Nicotiana, Arabidopsis, ducKweed, corn, wheat, potato, etc. Bacterial host cells include E. coli and Streptomyces species. Yeast host cells include Schizosaccharomyces pombe, Saccharomyces cerevisiae and Pichia pastoris. [00272] Further, expression of the polypeptides according to at least some embodiments of the invention (or other moieties derived therefrom) from production cell lines can be enhanced using a number of KNOwn techniques. For EXAMPLE, the glutamine synthetase gene expression system (the GS system) is a common approach for enhancing expression under certain conditions. The GS system is discussed in whole or part in connection with European Patent NOs. 0 216 846,0 256 055,0 338 841 and 0 323 997. [00273] It is liKely that polypeptides expressed by different cell lines or in transgenic animals will have different glycosylation patterns. However, all polypeptides encoded by the nucleic acid molecμles provided herein, or comprising the amino acid sequences provided herein are part of the instant invention, regardless of their glycosylation pattern. [00274] VECTORS [00275] According to at least some embodiments, the invention provides vectors comprising the nucleic acid molecμles that encode the polypeptides, fusion proteins, modified polypeptides, and polypeptide fragments of at least some embodiments the invention. [00276] To express the polypeptides according to at least some embodiments of the invention, or fragments thereof, DNAs encoding partial or fμll-length polypeptides, obtained as described above, are inserted into expression vectors such that the genes are operatively linKed to transcriptional and translational control sequences. Expression vectors include plasmids, retroviruses, adenoviruses, adeno-associated viruses (AAV), μlant viruses such as cauliflower mosaic virus, tobacco mosaic virus, cosmids, YACs, EBV derived episomes, and the liKe. The gene is ligated into a vector such that transcriptional and translational control sequences within the vector serve their intended function of regplating the transcription and translation of the gene. The expression vector and expression control sequences are chosen to be compatible with the expression host cell used. The gene is inserted into the expression vector by standard mehods (e.g., ligation of comμlementary restriction sites on the gene fragment and vector, or blunt end ligation if NO restriction sites are present). [00277] A convenient vector is one that encodes a functionally comμlete sequence, with appropriate restriction sites engineered so that any sequence can be easily inserted and expressed, as described above. Polyadenylation and transcription termination occur at native chromosomal sites downstream of the coding regions. The recombinant expression vector can also encode a signal peptide that facilitates secretion of the polypeptide from a host cell. The gene may be cloned into the vector such that the signal peptide is linKed in-frame to the amino terminus of the gene. [00278] In addition to the nucleic acid according to at least some embodiments of the invention, the recombinant expression vectors carry regμlatory sequences that control the expression of the gene in a host cell. It will be appreciated by those sKilled in the art that the design of the expression vector, including the selection of regμlatory sequences may depend on such factors as the choice of the host cell to be transformed, the level of expression of protein desired, etc. Preferred regμlatory sequences for mammalian host cell expression include viral elements that direct high levels of protein expression in mammalian cells, such as promoters and/or enhancers derived from retroviral LTRs, cytomegalovirus (CMV) (such as the CMV promoter/enhancer), Simian Virus 40 (SV40) (such as the SV40 promoter/enhancer), adenovirus, (e.g., the adenovirus major late promoter (AdMLP)), polyoma and strong mammalian promoters such as native immunogloulin and actin promoters. For further description of viral regμlatory elements, and sequences thereof, see e.g., U.S. Pat. NOs. 5,168,062, 4,510,245, and 4,968,615, each of which is hereby incorporated by reference. Methods of expressing polypeptides in bacterial cells or fungal cells, e.g., yeast cells, are also well KNOwn in the art. [00279] In addition to the nucleic acids according to at least some embodiments of the invention and regμlatory sequences, the recombinant expression vectors according to at least some embodiments of the invention may carry additional sequences, such as sequences that regplate reμlication of the vector in host cells (e.g., origins of reμlication) and selectable marKer genes. The selectable marKer gene facilitates selection of host cells into which the vector has been introduced (see, e.g., U.S. Pat, NOs. 4,399,216, 4,634,665 and 5,179,017). For EXAMPLE, typically the selectable marKer gene confers resistance to drugs, such as G418, hygromycin or methotrexate, on a host cell into which the vector has been introduced. Preferred selectable marKer genes include the dihydrofolate reductase (DHFR) gene, the neo gene (for G418 selection), and the glutamate synthetase gene. 100280] PROTEIN MODIFICATIONS [00281] FUSION PROTEINS [00282] The present invention encompasses fusion proteins (conjugates) for use in therapy, comprising the TMEM154 soluble portions including the ectodomain or portions or variants thereof. For EXAMPLE the invention encompasses conjugates wherein me ECD of the TMEM154 is attached to an immunogloulin or fragment thereof. The invention contemplates the use thereof for treating cancer and/or immune related conditions, diseases or disorders described herein. [00283] According to at least some embodiments, a fusion protein may be prepared from a protein according to at least some embodiments of the inventionby fusion with a portion of an immunogloulin comprising a constant region of an immunogloulin. Optionally, the portion of the immunogloulin comprises a heavy chain constant region which is optionally and more preferably a human heavy chain constant region. The heavy chain constant region is optionally an IgG heavy chain constant region, and optionally an Fc chain, or an IgG Fc fragment that comprises CH2 and CH3 domains. Although any IgG subtype may optionally be used, the IgGl subtype is preferred. The Fc chain may optionally be a KNOwn or "wild type" Fc chain, or alternatively may be mutated. non-limiting, illustrative, exemμlary types of mutations are described in US Patent Apμlication NO. 20060034852, published on February 16, 2006, hereby incorporated by reference as if fμlly set forth herein. The term "Fc chain" also optionally comprises any type of Fc fragment, [00284] Several of the specific amino acid residues that are important for antibody constant region-mediated activity in the IgG subclass have been identified. Inclusion, substitution or exclusion of these specific amino acids therefore allows for inclusion or exclusion of specific immunogloulin constant region-mediated activity. Furthermore, specific changes may resμlt in aglycosylation for EXAMPLE and/or other desired changes to the Fc chain. At least some changes may optionally be made to blocK a function of Fc which is considered to be undesirable, such as an undesirable immune system effect, as described in greater detail below. [00285] non-Hmiting, illustrative EXAMPLEs of mutations to Fc which may be made to modplate the activity of the fusion protein include the following changes (given with regard to the Fc sequence NOmenclature as given by Kabat, from Kabat EA et al: Sequences of Proteins of ImmuNOlogical Interest. US Department of Health and Human Services, NIH, 1991): 220C - > S; 233-238 ELLGGP - > EAEGAP; 265D - > A, preferably in combination with 434N -> A; 297N - > A (for EXAMPLE to blocK N-glycosylation); 318-322 EYKCK - > AYACA; 330-331AP - > SS; or a combination thereof (see for EXAMPLE M. ClarK, "Chemical ImmuNOl and Antibody Engineering", pp 1-31 for a description of these mutations and their effect). The construct for the Fc chain which features the above changes optionally and preferably comprises a combination of the hinge region with the CH2 and CH3 domains. [00286] The above mutations may optionally be imμlemented to enhance desired properties or alternatively to blocK non-desired properties. For EXAMPLE, aglycosylation of antibothes was shown to maintain the desired binding functionality while blocKing deμletion of T-cells or triggering cytoKine release, which may optionally be undesired functions (see M. ClarK, "Chemical ImmuNOl and Antibody Engineering", pp 1-31). Substitution of 331 proline for serine may blocK the ability to activate comμlement, which may optionally be considered an undesired function (see M. ClarK, "Chemical ImmuNOl and Antibody Engineering", pp 1-31). Changing 330alanine to serine in combination with this change may also enhance the desired effect of blocKing the ability to activate comμlement. [00287] Residues 235 and 237 were shown to be involved in antibody-dependent cell- mediated cytotoxicity (ADCC), such that changing the blocK of residues from 233-238 as described may also blocK such activity if ADCC is considered to be an undesirable function. [00288] Residue 220 is normally a cysteine for Fc from IgGl, which is the site at which the heavy chain forms a covalent linKage with the light chain. Optionally, this residue may be changed to a serine, to avoid any type of covalent linKage (see M. ClarK, "Chemical ImmuNOl and Antibody Engineering", pp 1-31). [00289] The above changes to residues 265 and 434 may optionally be imμlemented to reduce or blocK binding to the Fc receptor, which may optionally blocK undesired functionality of Fc related to its immune system functions (see "Binding site on Human IgGl for Fc Receptors", Shields et al, Vol 276, pp 6591-6604, 2001). [00290] The above changes are intended as illustrations only of optional changes and are not meant to be limiting in any way. Furthermore, the above exμlanation is provided for descriptive purposes only, without wishing to be bound by a single hypothesis. [00291] ADDITION OF GROUPS [00292] If a protein according to the present invention is a linear molecμle, it is possible to μlace various functional groups at various points on the linear molecμle which are susceptible to or suitable for chemical modification. Functional groups can be added to the termini of linear forms of the protein according to at least some embodiments of the invention. In some embodiments, the functional groups improve the activity of the protein with regard to one or more characteristics, including but not limited to, improvement in stability, penetration (through cellμlar membranes and/or tissue barriers), tissue localization, efficacy, decreased clearance, decreased toxicity, improved selectivity, improved resistance to expμlsion by cellμlar pumps, and the liKe. For convenience saKe and without wishing to be limiting, the free N-terminus of one of the sequences contained in the compositions according to at least some embodiments of the invention will be termed as the N-terminus of the composition, and the free C-terminal of the sequence will be considered as the C- terminus of the composition. Either the C-terminus or the N-terminus of the sequences, or both, can be linKed to a carboxylic acid functional groups or an amine functional group, respectively, [00293] non-limiting EXAMPLEs of suitable functional groups are described in Green and Wuts, "Protecting Groups in Organic Synthesis", John Wiley and Sons, Chapters 5 and 7, 1991, the teachings of which are incorporated herein by reference, Preferred protecting groups are those that facilitate transport of the active ingrethent attached thereto into a cell, for EXAMPLE, by reducing the hydrophilicity and increasing the lipophilicity of the active ingrethent, these being an EXAMPLE for "a moiety for transport across cellμlar membranes". [00294] These moieties can optionally be cleaved in vivo, either by hydrolysis or enzymatically, inside the cell. (Ditter et al„ J. Pharm. Sci. 57:783 (1968); Ditter et al., J. Pharm. Sci. 57:828 (1968); Ditter et al„ J. Pharm. Sci. 58:557 (1969); King et al., Biochemistry 26:2294 (1987); Lindberg et al., Drug Metabolism and Disposition 17:311 (1989); and TuneK et al., Biochem. Pharm. 37:3867 (1988), Anderson et al., Arch. Biochem. Biophys. 239:538 (1985) and Singhal et al., FASEB J. 1:220 (1987)). Hydroxyl protecting groups include esters, carbonates and carbamate protecting groups. Amine protecting groups include alKoxy and aryloxy carbonyl groups, as described above for N-terminal protecting groups. Carboxylic acid protecting groups include aliphatic, benzylic and aryl esters, as described above for C-terminal protecting groups. In one embodiment, the carboxylic acid group in the side chain of one or more glutamic acid or aspartic acid residue in a composition according to at least some embodiments of the present invention is protected, optionally with a metiiyl, ethyl, benzyl or substituted benzyl ester, [00295] non-limiting, illustrative EXAMPLEs of N-terminal protecting groups include acyl groups (-CO-R1) and alKoxy carbonyl or aryloxy carbonyl groups (-CO-0-R1), wherein Rl is an aliphatic, substituted aliphatic, benzyl, substituted benzyl, aromatic or a substituted aromatic group. Specific EXAMPLEs of acyl groups include but are not limited to acetyl, (ethyl)-CO-, n-propyl-CO, iso-propyl-CO-, n-butyl-CO-, sec-butyl-CO-, t-butyl-CO-, hexyl, lauroyl, palmitoyl, myristoyl, stearyl, oleoyl phenyl-CO-, substituted phenyl-CO-, benzyl-CO- and (substituted benzyl)-CO-. EXAMPLEs of alKoxy carbonyl and aryloxy carbonyl groups include CH3-0-CO-, (ethyl)-O-CO-, n-propyl-O-CO-, iso-propyl-O-CO-, n-butyl-O-CO-, sec-butyl-O-CCK t-butyl-O-CO-, phenyl-O- CO-, substituted phenyl-O-CO- and benzyl-O-CO-, (substituted benzyl)- 0-CO-, Adamantan, naphtalen, myristoleyl, toluen, biphenyl, cinnamoyl, nitrobenzoy, toluoyl, furoyl, benzoyl, cyclohexane, NOrbornane, or Z-caproic. In order to facilitate the N-acylation, one to four glycine residues can be present in the N-terminus of the molecμle. [00296] The carboxyl group at the C-terminus of the compound can be protected, for EXAMPLE, by a group including but not limited to an amide (i.e., the hydroxyl group at the C-terminus is reμlaced with -NH 2, -NHR2 and -NR2R3) or ester (i.e. the hydroxyl group at the C-terminus is reμlaced with -OR2). R2 and R3 are optionally independently an aliphatic, substituted aliphatic, benzyl, substituted benzyl, aryl or a substituted aryl group. In addition, taKen together with the nitrogen atom, R2 and R3 can optionally form a C4 to C8 heterocyclic ring with from about 0-2 additional heteroatoms such as nitrogen, oxygen or sμlfur. non-limiting suitable EXAMPLEs of suitable heterocyclic rings include piperidinyl, pyrrotidinyl, morpholiNO, thiomorpholiNO or piperazinyl. EXAMPLEs of C-terminal protecting groups include but are not limited to -NH2, -NHCH3, -N(CH3)2, -NH(ethyl), -N(ethyl)2, -N(methyl) (ethyl), -NH(benzyl), -N(C1-C4 alKyD(benzyl), -NH(phenyl), -N(C1-C4 alKyl) (phenyl), -OCH3, -O-(efhyl), -O-(n-propyl), -O-(n-butyl), -O-(iso-propyl), -0-(sec- butyl), -O-(t-butyl), -O-benzyl and -O-phenyl, [00297] SUBSTITUTION BY PEPTIDOMIMETIC MOIETIES [00298] A "peptidomimetic organic moiety" can optionally be substituted for amino acid residues in the composition of this invention both as conservative and as non-conservative substitutions. These moieties are also termed "non-natural amino acids" and may optionally reμlace amino acid residues, amino acids or act as spacer groups within the peptides in lieu of deleted amino acids. The peptidomimetic organic moieties optionally have steric, electronic or configurational properties similar to the reμlaced amino acid and such peptidomimetics are used to reμlace amino acids in the essential positions, and are considered conservative substitutions. However such similarities are not necessarily required. According to at least some embodiments of the present invention, one or more peptidomimetics are selected such that the composition at least substantially retains its physiological activity as compared to the native protein according to the present invention. [00299] Peptidomimetics may optionally be used to inhibit degradation of the peptides by enzymatic or other degradative processes. The peptidomimetics can optionally be produced by organic synthetic techniques. non-limiting EXAMPLEs of suitable peptidomimetics include D amino acids of the corresponding L amino acids, tetrazol (ZabrocKi et al„ J, Am. Chem. Soc. 110:5875-5880 (1988)); isosteres of amide bonds (Jones et al., Tetrahedron Lett. 29: 3853-3856 (1988)); LL-3-amino-2-propenidone-6-carboxylic acid (LL-Acp) (Kemp et al„ J. Org. Chem. 50:5834-5838 (1985)). Similar analogs are shown in Kemp et al., Tetrahedron Lett. 29:5081-5082 (1988) as well as Kemp et al., Tetrahedron Lett. 29:5057-5060 (1988), Kemp et al., Tetrahedron Lett. 29:4935-4938 (1988) and Kemp et al., J. Org. Chem. 54:109-115 (1987). Other suitable but exemμlary peptidomimetics are shown in Nagai and Sato, Tetrahedron Lett. 26:647-650 (1985); Di Maio et al., J. Chem. Soc. PerKin Trans,, 1687 (1985); Kahn et al., Tetrahedron Lett. 30:2317 (1989); Olson et al., J. Am. Chem. Soc. 112:323-333 (1990); Garvey et al., J. Org. Chem. 56:436 (1990). Further suitable exemμlary peptidomimetics include hydroxy- 1,2,3,4'tetrahydroisoquiNOline- 3-carboxylate (MiyaKe et al., J. TaKeda Res. Labs 43:53-76 (1989)); 1,2,3,4-tetrahydro- isoquiNOline-3-carboxylate (KazmiersKi et al., J. Am. Chem. Soc. 133:2275-2283 (1991)); histidine isoquiNOlone carboxylic acid (HIC) (Zechel et al., Int. J. Pep. Protein Res. 43 (1991)); (2S, 3S)-methyl-phenylalanine, (2S, 3R)-methyl-phenylalanine, (2R, 3S)-methyl- phenylalanine and (2R, 3R)-methyl-phenylalanine (KazmiersKi and Hruby, Tetrahedron Lett. (1991)). [00300] Exemμlary, illustrative but non-limiting non-natural amino acids include beta- amino acids (beta3 and beta2), homo-amino acids, cyclic amino acids, aromatic amino acids, Pro and Pyr derivatives, 3-substituted Alanine derivatives, Glycine derivatives, ring- substituted Phe and Tyr Derivatives, linear core amino acids or diamine acids. They are available from a variety of supμliers, such as Sigma-Aldrich (USA) for EXAMPLE, [00301] CHEMICAL MODIFICATIONS [00302] In the present invention any part of a protein according to at least some embodiments of the invention may optionally be chemically modified, i.e. changed by addition of functional groups. For EXAMPLE the side amino acid residues appearing in the native sequence may optionally be modified, although as described below alternatively other parts of the protein may optionally be modified, in addition to or in μlace of the side amino acid residues. The modification may optionally be performed during synthesis of the molecμle if a chemical synthetic process is followed, for EXAMPLE by adding a chemically modified amino acid. However, chemical modification of an amino acid when it is already present in the molecμle ("in situ" modification) is also possible. [00303] The amino acid of any of the sequence regions of the molecμle can optionally be modified according to any one of the following exemμlary types of modification (in the peptide conceptually viewed as "chemically modified"). non-limiting exemμlary types of modification include carboxymethylation, acylation, phosphorylation, glycosylation or fatty acylation. Ether bonds can optionally be used to join the serine or threonine hydroxy! to the hydroxyl of a sugar. Amide bonds can optionally be used to join the glutamate or aspartate carboxyl groups to an amino group on a sugar (Garg and Jeanloz, Advances in Carbohydrate Chemistry and Biochemistry, Vol. 43, Academic Press (1985); Kunz, Ang, Chem. Int. Ed. English 26:294-308 (1987)). Acetal and Ketal bonds can also optionally be formed between amino acids and carbohydrates. Fatty acid acyl derivatives can optionally be made, for EXAMPLE, by acylation of a free amino group (e.g., lysine) (Toth et al., Peptides: Chemistry, Structure and Biology, Rivier and Marshal, eds., ESCOM Publ., Leiden, 1078-1079(1990)). [00304] As used herein the term "chemical modification", when referring to a protein or peptide according to the present invention, refers to a protein or peptide where at least one of its amino acid residues is modified either by natural processes, such as processing or other post-translational modifications, or by chemical modification techniques which are well KNOwn in the art. EXAMPLEs of the numerous KNOwn modifications typically include, but are not limited to: acetylation, acylation, amidation, ADP-ribosylation, glycosylation, GPI anchor formation, covalent attachment of a lipid or lipid derivative, methylation, myristylation, pegylation, prenylation, phosphorylation, ubiquitination, or any similar process. [00305] Other types of modifications optionally include the addition of a cycloalKane moiety to a biological molecμle, such as a protein, as described in PCT Apμlication NO. WO 2006/050262, hereby incorporated by reference as if fμlly set forth herein. These moieties are designed for use with biomolecμles and may optionally be used to impart various properties to proteins. [00306] Furthermore, optionally any point on a protein may be modified. For EXAMPLE, pegylation of a glycosylation moiety on a protein may optionally be performed, as described in PCT Apμlication NO. WO 2006/050247, hereby incorporated by reference as if fμlly set forth herein. One or more polyethylene glycol (PEG) groups may optionally be added to O- linKed and/or N-linKed glycosylation. The PEG group may optionally be branched or linear. Optionally any type of water-soluble polymer may be attached to a glycosylation site on a protein through a glycosyl linKer. [00307] ALTERED GLYCOSYLATION [00308] Proteins according to at least some embodiments of the invention may be modified to have an altered glycosylation pattern (i.e., altered from the original or native glycosylation pattern). As used herein, "altered" means having one or more carbohydrate moieties deleted, and/or having at least one glycosylation site added to the original protein. [00309] Glycosylation of proteins is typically either N-IinKed or O-linKed. N-linKed refers to the attachment of the carbohydrate moiety to the side chain of an asparagine residue. The tripeptide sequences, asparagine-X-serine and asparagine-X-threonine, where X is any amino acid except proline, are the recognition sequences for enzymatic attachment of the carbohydrate moiety to the asparagine side chain. Thus, the presence of either of these tripeptide sequences in a polypeptide creates a potential glycosylation site. O-linKed glycosylation refers to the attachment of one of the sugars N-acetylgalactosamine, galactose, or xylose to a hydroxyamino acid, most commonly serine or threonine, although 5-hydroxyproline or 5-hydroxylysine may also be used. [00310] Addition of glycosylation sites to proteins according to at least some embodiments of the invention is conveniently accomμlished by altering the amino acid sequence of the protein such that it contains one or more of the above-described tripeptide sequences (for N-linKed glycosylation sites). The alteration may also be made by the addition of, or substitution by, one or more serine or threonine residues in the sequence of the original protein (for O-linKed glycosylation sites). The protein's amino acid sequence may also be altered by introducing changes at the DNA level. [00311] Another means of increasing the number of carbohydrate moieties on proteins is by chemical or enzymatic couμling of glycosides to the amino acid residues of the protein. Depending on the couμling mode used, the sugars may be attached to (a) arginine and histidine, (b) free carboxyl groups, (c) free sμlfhydryl groups such as those of cysteine, (d) free hydroxyl groups such as those of serine, threonine, or hydroxyproline, (e) aromatic residues such as those of phenylalanine, tyrosine, or tryptophan, or (f) the amide group of glutamine. These methods are described in WO 87/05330, and in Aμlin and Wriston, CRC Crit. Rev. Biochem., 22: 259-306 (1981). [00312] Removal of any carbohydrate moieties present on proteins according to at least some embodiments of the invention may be accomμlished chemically or enzymatically. Chemical deglycosylation requires exposure of the protein to trifluoromemanesμlfonic acid, or an equivalent compound. This treatment ^resμlts in the cleavage of most or all sugars except the linKing sugar (N-acetylglucosamine or N-acetylgalactosamine), leaving the amino acid sequence intact. [00313] Chemical deglycosylation is described by HaKimuddin et al., Arch. Biochem. Biophys., 259: 52 (1987); and Edge et al., Anal. Biochem., 118: 131 (1981). Enzymatic cleavage of carbohydrate moieties on proteins can be achieved by the use of a variety of endo- and exo-glycosidases as described by ThotaKura et al., Meth. Enzymol., 138: 350 (1987). [00314] METHODS OF TREATMENT USING TMEM154 POLYPEPTIDES AND PROTEINS As mentioned hereinabove the TMEM154 proteins and polypeptides according to at least some embodiments of the present invention or nucleic acid sequence or fragments thereof especially the ectodomain or secreted forms of TMEM154 proteins and polypeptides, can be used to treat cancer, including but not limited to lymphoma, especially non-HodgKin's Lymphoma, anti CD20 (i.e. Rituximab) resistant lymphoma, Mμltiμle Myeloma, Kidney cancer, and pancreatic cancer, and/or immune related conditions or disorders. [00315] Thus, according to at least some embodiments of the present invention there is provided a method of treating cancer, and/or immune related conditions or disorders [00316] As used herein the term "treating" refers to preventing, curing, reversing, attenuating, alleviating, minimizing, suppressing or halting the deleterious effects of the above-described diseases, disorders or conditions. The term treatment as used herein refers also to "maintenance therapy", which is a treatment that is given to Keep a pathologic condition or disorder from coming bacK after it has disappeared following the initial therapy. [00317] Treating, according to the present invention, can be effected by specifically upregplating the expression of at least one of the polypeptides according to at least some embodiments of the present invention in the subject. [00318] Optionally, upregμlation may be effected by administering to the subject at least one of the polypeptides according to at least some embodiments of the present invention (e.g., recombinant or synthetic) or an active portion thereof, as described herein. However, since the bioavailability of large polypeptides may potentially be relatively small due to high degradation rate and low penetration rate, administration of polypeptides is preferably confined to small peptide fragments (e.g., about 100 amino acids). The polypeptide or peptide may optionally be administered in as part of a pharmaceutical composition, described in more detail below. [00319] It will be appreciated that treatment of the above-described diseases according to the present invention may be combined with other treatment methods KNOwn in the art (i.e., combination therapy). [00320] ANTI-KRTCAP3, ANTI-FAM26F, ANTI-MGC52498, ANTI-FAM70A, ANTI-TMEM154 ANTIBOtheS [00321] The antibothes according to at least some embodiments of the invention including those having the particμlar germline sequences, homologous antibothes, antibothes with conservative modifications, engineered and modified antibothes are characterized by particμlar functional features or properties of the antibothes. For EXAMPLE, the antibothes bind specifically to human KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides. Optionally, an antibody according to at least some embodiments of the invention binds to corresponding KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides with high affinity, for EXAMPLE with a KD of 10 -8 M or less or 10 -9 M or less or even 10 -10 M or less. The Anti-KRTCAP3, Anti-FAM26F, Anti- MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes according to at least some embodiments of the invention optionally exhibit one or more of the following characteristics: [00322] (i) binds to one of the corresponding human KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides with a KD of 5.X10 -8 M or less; [00323] (ii) binds to one of the KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen expressed by cancer cells including for EXAMPLE ovarian cancer, lung cancer, colon cancer, breast cancer, Kidney cancer, liver cancer, pancreatic cancer, prostate cancer, melaNOma and hematological malignancies such as Mμltiμle Myeloma, lymphoma, non-HodgKin's lymphoma, anti CD20 (i.e. Rituximab) resistant lymphoma, leuKemia, T cell leuKemia, but does not substantially bind to normal cells. In addition, optionally these antibothes and conjugates thereof will be effective in eliciting selective Killing of such cancer cells and for modplating immune responses involved in autoimmunity and cancer. [00324] Optionally, the antibody binds to one of the corresponding human KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigens with a KD of 3X10 -8 M or less, or with a KD of 1X10 -9 M or less, or with a KD of 0.1.X10 -9 M or less, or with a KD Of 0.05.X10 -9 M or less or with a KD of between 1X10 -9 and 1X10 -11 M. [00325] Standard assays to evaluate the binding ability of the antibothes toward KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptides arc KNOwn in the art, including for EXAMPLE, ELISAs, Western blots and RIAs. Suitable assays are described in detail in the EXAMPLEs. The binding Kinetics (e.g., binding affinity) of the antibothes also can be assessed by standard assays KNOwn in the art, such as by Biacore analysis. [00326] Upon production of Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, And- FAM70A, Anti-TMEM154 antibody sequences from antibothes can bind to KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 the VH and VL sequences can be "mixed and matched" to create other anti-KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 binding molecμles according to at least some embodiments of the invention. KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 binding of such "mixed and matched" antibothes can be tested using the binding assays described above, e.g., ELISAs). Optionally, when VH and VL chains are mixed and matched, a VH sequence from a particμlar VH/VL pairing is reμlaced with a structurally similar VH sequence. LiKewise, optionally a VL sequence from a particμlar VH/VL pairing is reμlaced with a structurally similar VL sequence. For EXAMPLE, the VH and VL sequences of homologous antibothes are particμlarly amenable for mixing and matching. [00327] ANTIBOtheS HAVING PARTICμlAR GERMLINE SEQUENCES [00328] In certain embodiments, an antibody according to at least some embodiments of the invention comprises a heavy chain variable region from a particμlar germline heavy chain immunogloulin gene and/or a light chain variable region from a particμlar germline light chain immunogloulin gene. [00329] As used herein, a human antibody comprises heavy or light chain variable regions that is "the product of" or "derived from" a particμlar germline sequence if the variable regions of the antibody are obtained from a system that uses human germline immunogloulin genes. Such systems include immunizing a transgenic mouse carrying human immunogloulin genes with the antigen of interest or screening a human immunogloulin gene library disμlayed on phage with the antigen of interest. A human antibody that is "the product of or "derived from" a human germline immunogloulin sequence can be identified as such by comparing the amino acid sequence of the human antibody to the amino acid sequences of human germline immunogloulins and selecting the human germline immunogloulin sequence mat is closest in sequence (i.e., greatest % identity) to the sequence of the human antibody. [00330] A human antibody that is "the product of" or "derived from" a particμlar human germline immunogloulin sequence may contain amino acid differences as compared to the germline sequence, due to, for EXAMPLE, naturally-occurring somatic mutations or intentional introduction of site-directed mutation. However, a selected human antibody typically is at least 90% identical in amino acids sequence to an amino acid sequence encoded by a human germline immunogloulin gene and contains amino acid residues that identify the human antibody as being human when compared to the germline immunogloulin amino acid sequences of other species (e.g., murine germline sequences). In certain cases, a human antibody may be at least 95, 96, 97, 98 or 99%, or even at least 96%, 97%, 98%, or 99% identical in amino acid sequence to the amino acid sequence encoded by the germline immunogloulin gene. Typically, a human antibody derived from a particμlar human germline sequence will disμlay NO more than 10 amino acid differences from the amino acid sequence encoded by the human germline immunogloulin gene. In certain cases, the human antibody may disμlay NO more than 5, or even NO more than 4, 3, 2, or 1 amino acid difference from the amino acid sequence encoded by the germline immunogloulin gene. [00331] HOMOLOGOUS ANTIBOtheS [00332] In yet another embodiment, an antibody according to at least some embodiments of the invention comprises heavy and light chain variable regions comprising amino acid sequences that are homologous to isolated Anti-KRTCAP3, Anti-FAM26F, Anti- MGC52498, Anti-FAM70A, Anti-TMEM154 amino acid sequences of preferred Anti- KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes, respectively, wherein the antibothes retain the desired functional properties of the parent Anti-KRTCAP3, Anfi-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes. [00333] As used herein, the percent homology between two amino acid sequences is equivalent to the percent identity between the two sequences. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % homo!ogy=# of identical positions/total # of positions X 100), taKing into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomμlished using a mathematical algorithm, as described in the non-limiting EXAMPLEs below. [00334] The percent identity between two amino acid sequences can be determined using the algorithm of E. Meyers and W. Miller (Comput. Apμl. Biosci., 4; 11-17 (1988)) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. In addition, the percent identity between two amino acid sequences can be determined using the Needleman and Wunsch (J. Mol. Biol. 48:444-453 (1970)) algorithm which has been incorporated into the GAP program in the GCG software pacKage (available commercially), using either a Blossum 62 matrix or a PAM250 matrix, and a gap weight of 16,14,12,10, 8, 6, or 4 and a length weight of 1, 2,3,4, 5, or 6. [00335] Additionally or alternatively, the protein sequences according to at least some embodiments of the present invention can further be used as a "query sequence" to perform a search against public databases to, for EXAMPLE, identify related sequences. Such searches can be performed using the XBLAST program (version 2.0) of Altschμl, et al. (1990) J Mol. Biol. 215:403-10. BLAST protein searches can be performed with the XBLAST program, score=50, wordlength=3 to obtain amino acid sequences homologous to the antibody molecμles according to at least some embodiments of the invention. To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschμl et al., (1997) Nucleic Acids Res. 25(17):3389-3402. When utilizing BLAST and Gapped BLAST programs, the defaμlt parameters of the respective programs (e.g., XBLAST and NBLAST) can be used. [00336] Antibothes with Conservative Modifications [00337] In certain embodiments, an antibody according to at least some embodiments of the invention comprises a heavy chain variable region comprising CDR1, CDR2 and CDR3 sequences and a light chain variable region comprising CDR1, CDR2 and CDR3 sequences, wherein one or more of these CDR sequences comprise specified amino acid sequences based on preferred Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes isolated and produced using methods herein, or conservative modifications thereof, and wherein the antibothes retain the desired functional properties of the Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes according to at least some embodiments of the invention, respectively. [00338] In various embodiments, the Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibody can be, for EXAMPLE, human antibothes, humanized antibothes or chimeric antibothes. [00339] As used herein, the term "conservative sequence modifications" is intended to refer to amino acid modifications that do not significantly affect or alter the binding characteristics of the antibody containing the amino acid sequence. Such conservative modifications include amino acid substitutions, additions and deletions. Modifications can be introduced into an antibody according to at least some embodiments of the invention by standard techniques KNOwn in the art, such as site-directed mutagenesis and PCR-mediated mutagenesis. Conservative amino acid substitutions are ones in which the amino acid residue is reμlaced with an amino acid residue having a similar side chain. Families of amino acid residues having similar side chains have been defined in the art. These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine, tryptophan), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine), beta- branched side chains (e.g., threonine, valine, isoleucine) and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine). Thus, one or more amino acid residues within the CDR regions of an antibody according to at least some embodiments of the invention can be reμlaced witfi other amino acid residues from the same side chain family and the altered antibody can be tested for retained function (i.e., the functions set forth in (c) through (j) above) using the functional assays described herein. [00340] ENGINEERED AND MODIFIED ANTIBOtheS [00341] An antibody according to at least some embodiments of the invention can be prepared using an antibody having one or more of the VH and/or VL sequences derived from an Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti- TMEM154antibody starting material to engineer a modified antibody, which modified antibody may have altered properties from the starting antibody. An antibody can be engineered by modifying one or more residues within one or bom variable regions (i.e., VH and/or VL), for EXAMPLE within one or more CDR regions and/or within one or more frameworK regions. Additionally or alternatively, an antibody can be engineered by modifying residues within the constant regions, for EXAMPLE to alter the effector functions of me antibody, [00342] One type of variable region engineering that can be performed is CDR grafting. Antibothes interact with target antigens predominantly through amino acid residues mat are located in the six heavy and light chain comμlementarity determining regions (CDRs), For this reason, the amino acid sequences within CDRs are more diverse between individual antibothes than sequences outside of CDRs. Because CDR sequences are responsible for most antibody-antigen interactions, it is possible to express recombinant antibothes that mimic the properties of specific naturally occurring antibothes by constructing expression vectors that include CDR sequences from the specific naturally occurring antibody grafted onto frameworK sequences from a different antibody with different properties (see, e.g., Riechmann, L. et al. (1998) Nature 332:323-327; Jones, P. et al. (1986) Nature 321:522- 525; Queen, C. et al. (1989) Proc. Natl. Acad. See. U.S.A. 86:10029-10033; U.S. Pat. NO. 5,225,539 to Winter, and U.S. Pat. NOs. 5,530,101; 5,585,089; 5,693,762 and 6,180,370 to Queen et al.) [00343] Suitable frameworK sequences can be obtained from public DNA databases or published references that include germline antibody gene sequences. For EXAMPLE, germline DNA sequences for human heavy and light chain variable region genes can be found in the "VBase" human germline sequence database (available on the Internet), as well as in Kabat, E. A., et al. (1991) Sequences of Proteins of ImmuNOlogical Interest, Fifth Edition, U.S. Department of Health and Human Services, NTH Publication NO. 91-3242; Tomlinson, I. M„ et al. (1992) "The Repertoire of Human Germline VH Sequences Reveals about Fifty Groups of VH Segments with Different Hypervariable 100ps" J. Mol. Biol. 227:776-798; and Cox, J. P. L. et al. (1994) "A Directory of Human Germ-line VH Segments Reveals a Strong Bias in their Usage" Eur. J ImmuNOl, 24:827-836; the contents of each of which are expressly incorporated herein by reference, [00344] Another type of variable region modification is to mutate amino acid residues within the VH and/or VL CDR 1, CDR2 and/or CDR3 regions to thereby improve one or more binding properties (e.g., affinity) of the antibody of interest. Site-directed mutagenesis or PCR-mediated mutagenesis can be performed to introduce the mutations and the effect on antibody binding, or other functional property of interest, can be evaluated in appropriate in vitro or in vivo assays. Optionally conservative modifications (as discussed above) are introduced. The mutations may be amino acid substitutions, additions or deletions, but are preferably substitutions. Moreover, typically NO more than one, two, three, four or five residues within a CDR region are altered. [00345] Engineered antibothes according to at least some embodiments of the invention include those in which modifications have been made to frameworK residues within VH and/or VL, e.g. to improve the properties of the antibody. Typically such frameworK modifications are made to decrease the immuNOgenicity of the antibody. For EXAMPLE, one approach is to "bacKmutate" one or more frameworK residues to the corresponding germline sequence. More specifically, an antibody that has undergone somatic mutation may contain frameworK residues that differ from the germline sequence from which the antibody is derived. Such residues can be identified by comparing the antibody frameworK sequences to the germline sequences from which the antibody is derived, [00346] In addition or alternative to modifications made within the frameworK or CDR regions, antibothes according to at least some embodiments of the invention may be engineered to include modifications within the Fc region, typically to alter one or more functional properties of the antibody, such as serum half-life, comμlement fixation, Fc receptor binding, and/or antigen-dependent cellμlar cytotoxicity. Furthermore, an antibody according to at least some embodiments of the invention may be chemically modified (e.g., one or more chemical moieties can be attached to the antibody) or be modified to alter its glycosylation, again to alter one or more functional properties of the antibody. Such embodiments are described further below. The numbering of residues in the Fc region is that of the EU index of Kabat. [00347] In one embodiment, the hinge region of CH1 is modified such that the number of cysteine residues in the hinge region is altered, e.g., increased or decreased. This approach is described further in U.S. Pat. NO, 5,677,425 by Bodmer et al. The number of cysteine residues in the hinge region of CHI is altered to, for EXAMPLE, facilitate assembly of the light and heavy chains or to increase or decrease the stability of the antibody. [00348] In another embodiment, the Fc hinge region of an antibody is mutated to decrease the biological half life of the antibody. More specifically, one or more amino acid mutations are introduced into the CH2-CH3 domain interface region of the Fc-hinge fragment such that the antibody has impaired Staphylococcyl protein A (SpA) binding relative to native Fc-hinge domain SpA binding. This approach is described in further detail in U.S. Pat. NO. 6,165,745 by Ward et al. [00349] In another embodiment, the antibody is modified to increase its biological half life. Various approaches are possible. For EXAMPLE, one or more of the following mutations can be introduced: T252L, T254S, T256F, as described in U.S. Pat. NO. 6,277,375 to Ward. Alternatively, to increase the biological half life, the antibody can be altered within the CHI or CL region to contain a salvage receptor binding epitope taKen from two 100ps of a CH2 domain of an Fc region of an IgG, as described in U.S. Pat. NOs. 5,869,046 and 6,121,022 by Prestaet al. [00350] In yet other embodiments, the Fc region is altered by reμlacing at least one amino acid residue with a different amino acid residue to alter the effector functions of the antibody. For EXAMPLE, one or more amino acids selected from amino acid residues 234, 235, 236, 237, 297, 318, 320 and 322 can be reμlaced with a different amino acid residue such that the antibody has an altered affinity for an effector ligand but retains the antigen- binding ability of the parent antibody. The effector ligand to which affinity is altered can be, for EXAMPLE, an Fc receptor or the CI component of comμlement. This approach is described in further detail in U.S. Pat. NOs. 5,624,821 and 5,648,260, both by Winter et al. [00351] In another EXAMPLE, one or more amino acids selected from amino acid residues 329, 331 and 322 can be reμlaced with a different amino acid residue such that the antibody has altered Clq binding and/or reduced or abolished comμlement dependent cytotoxicity (CDC). This approach is described in further detail in U.S. Pat. NOs. 6,194,551 by Idusogie etal. [00352] In another EXAMPLE, one or more amino acid residues within amino acid positions 231 and 239 are altered to thereby alter the ability of the antibody to fix comμlement. This approach is described further in PCT Publication WO 94/29351 by Bodmer et al. [00353] In yet another EXAMPLE, the Fc region is modified to increase the ability of the antibody to mediate antibody dependent cellμlar cytotoxicity (ADCC) and/or to increase the affinity of the antibody for an Fey receptor by modifying one or more amino acids at the following positions: 238, 239, 248, 249, 252, 254, 255, 256, 258, 265, 267, 268, 269, 270, 272, 276, 278, 280, 283, 285, 286, 289, 290, 292, 293, 294, 295, 296, 298, 301, 303, 305, 307, 309, 312, 315, 320, 322, 324, 326, 327, 329, 330, 331, 333, 334, 335, 337, 338, 340, 360, 373, 376, 378, 382, 388, 389, 398, 414, 416, 419, 430, 434, 435, 437, 438 or 439. This approach is described further in PCT Publication WO 00/42072 by Presta. Moreover, the binding sites on human IgGl for Fc grammar, Fc gamma RU, Fc gammaRIII and FcRn have been mapped and variants with improved binding have been described (see Shields, R. L. et al. (2001) J. Biol. Chem. 276:6591-6604). Specific mutations at positions 256, 290, 298, 333, 334 and 339 are shown to improve binding to FcyRIII. Additionally, the following combination mutants are shown to improve Fcgamma.RIII binding: T256A/S298A, S298A/E333A, S298A/K224A and S298A/E333A/K334A. [00354] In still another embodiment, the glycosylation of an antibody is modified. For EXAMPLE, an aglycoslated antibody can be made (i.e., the antibody lacKs glycosylation). Glycosylation can be altered to, for EXAMPLE, increase the affinity of the antibody for antigen. Such carbohydrate modifications can be accomμlished by, for EXAMPLE, altering one or more sites of glycosylation within the antibody sequence. For EXAMPLE, one or more amino acid substitutions can be made that resμlt in elimination of one or more variable region frameworK glycosylation sites to thereby eliminate glycosylation at that site. Such aglycosylation may increase the affinity of the antibody for antigen. Such an approach is described in further detail in U.S. Pat. NOs. 5,714,350 and 6,350,861 by Co et al. [00355] Additionally or alternatively, an antibody can be made that has an altered type of glycosylation, such as a hypofucosylated antibody having reduced amounts of fucosyl residues or an antibody having increased bisecting GlcNac structures. Such altered glycosylation patterns have been demonstrated to increase the ADCC ability of antibothes. Such carbohydrate modifications can be accomμlished by, for EXAMPLE, expressing the antibody in a host cell with altered glycosylation machinery. Cells with altered glycosylation machinery have been described in the art and can be used as host cells in which to express recombinant antibothes according to at least some embodiments of the invention to thereby produce an antibody with altered glycosylation. For EXAMPLE, the cell lines Ms704, Ms705, and Ms709 lacK the fucosyltransferase gene, FUT8 (alpha (1,6) fucosyltransferase), such that antibothes expressed in the Ms704, Ms705, and Ms709 cell lines lacK fucose on their carbohydrates. The Ms704, Ms705, and Ms709 FUT8.-/- cell lines are created by the targeted disruption of the FUT8 gene in CHO/DG44 cells using two reμlacement vectors (see U.S. Patent Publication NO. 20040110704 by Yamane et al, and Yamane-OhnuKi et al. (2004) BiotechNOl Bioeng 87:614-22). As another EXAMPLE, EP 1,176,195 by Hanai et al. describes a cell line with a functionally disrupted FUT8 gene, which encodes a fucosyl transferase, such that antibothes expressed in such a cell line exhibit hypofucosylation by reducing or eliminating the alpha 1,6 bond-related enzyme. Hanai et al. also describe cell lines which have a low enzyme activity for adding fucose to the N-acetylglucosamine that binds to the Fc region of the antibody or does not have the enzyme activity, for EXAMPLE the rat myeloma cell line YB2/0 (ATCC CRL 1662). PCT Publication WO 03/035835 by Presta describes a variant CHO cell line, Lecl3 cells, with reduced ability to attach fucose to Asn(297) -linKed carbohydrates, also resμlting in hypofucosylation of antibothes expressed in that host cell (see also Shields, R, L. et al. (2002) J. Biol. Chem. 277:26733-26740). PCT Publication WO 99/54342 by Umana et al. describes cell lines engineered to express glycoprotein-modifying glycosyl transferases (e.g., beta(l,4)-N-acetylglucosaminyltransferase III (GnTIII)) such that antibothes expressed in the engineered cell lines exhibit increased bisecting GlcNac structures which resμlts in increased ADCC activity of the antibothes (see also Umana et al. (1999) Nat. Biotech. 17:176-180). Alternatively, the fucose residues of the antibody may be cleaved off using a fucosidase enzyme. For EXAMPLE, the fucosidase alpha-L-fucosidase removes fucosyl residues from antibothes (TarentiNO, A. L, et al. (1975) Biochem. 14:5516-23). [00356] Another modification of the antibothes herein that is contemplated by the invention is pegylation. An antibody can be pegylated to, for EXAMPLE, increase the biological (e.g., serum) half life of the antibody. To pegylate an antibody, the antibody, or fragment thereof, typically is reacted with polyethylene glycol (PEG), such as a reactive ester or aldehyde derivative of PEG, under conditions in which one or more PEG groups become attached to the antibody or antibody fragment. Optionally, the pegylation is carried out via an acylation reaction or an alKylation reaction with a reactive PEG molecμle (or an analogous reactive water-soluble polymer). As used herein, the term "polyethylene glycol" is intended to encompass any of the forms of PEG that have been used to derivatize other proteins, such as moNO (C1-C10) alKoxy- or aryloxy-polyethylene glycol or polyethylene glycol-maleimide. In certain embodiments, the antibody to be pegylated is an aglycosylated antibody. Methods for pegylating proteins are KNOwn in the art and can be apμlied to the antibothes according to at least some embodiments of the invention. See for EXAMPLE, EP 0 154 316 by Nishimura et al. and EP 0 401 384 by IshiKawa et al. [00357] METHODS OF ENGINEERING ANTIBOtheS [00358] As discussed above, the Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes having VH and VK sequences disclosed herein can be used to create new Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti- FAM70A, Anti-TMEM154antibothes, respectively, by modifying the VH and/or VL sequences, or the constant regions attached thereto. Thus, according to at least some embodiments of the invention, the structural features of an Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibody according to at least some embodiments of the invention, are used to create structurally related Anti-KRTCAP3, And- FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes that retain at least one functional property of the antibothes according to at least some embodiments of the invention, such as binding to human KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154, respectively. For EXAMPLE, one or more CDR regions of one KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antibody or mutations thereof, can be combined recombinantly with KNOwn frameworK regions and/or other CDRs to create additional, recombinantly-engineered, Anti-KRTCAP3, Anti-FAM26FF, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes according to at least some embodiments of the invention, as discussed above. Other types of modifications include those described in the previous section. The starting material for the engineering method is one or more of the VH and/or VK sequences provided herein, or one or more CDR regions thereof. To create the engineered antibody, it is not necessary to actually prepare (i.e., express as a protein) an antibody having one or more of the VH and/or VK sequences provided herein, or one or more CDR regions thereof. Rather, the information contained in the sequences is used as the starting material to create a "second generation" sequences derived from the original sequences and then the "second generation" sequences is prepared and expressed as a protein. [00359] Standard molecμlar biology techniques can be used to prepare and express altered antibody sequence. [00360] Optionally, the antibody encoded by the altered antibody sequences is one that retains one, some or all of the functional properties of the Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes, respectively, produced by methods and with sequences provided herein, which functional properties include binding to KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen with a specific KD level or less and/or selectively binding to desired target cells such as ovarian cancer, lung cancer, breast cancer, colon cancer, Kidney cancer, liver cancer, pancreatic cancer, prostate cancer, melaNOma and hematological malignancies such as Mμltiμle Myeloma, lymphoma, non-HodgKin's lymphoma, anti CD20 (i.e. Rituximab) resistant lymphoma, leuKemia, T cell leuKemia, that express KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen. [00361] The functional properties of the altered antibothes can be assessed using standard assays available in the art and/or described herein, [00362] In certain embodiments of the methods of engineering antibothes according to at least some embodiments of the invention, mutations can be introduced randomly or selectively along all or part of an Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti- FAM70A, Anti-TMEM154 antibody coding sequence and the resμlting modified Anti- KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes can be screened for binding activity and/or other desired functional properties. [00363] Mutational methods have been described in the art. For EXAMPLE, PCT Publication WO 02/092780 by Short describes methods for creating and screening antibody mutations using saturation mutagenesis, synthetic ligation assembly, or a combination thereof. Alternatively, PCT Publication WO 03/074679 by Lazar et al. describes methods of using computational screening methods to optimize physiochemical properties of antibothes. [00364] NUCLEIC ACID MOLECμlES ENCODING ANTIBOtheS [00365] According to at least some embodiments of the inventionpertains to nucleic acid molecμles that encode the antibothes according to at least some embodiments of the invention. The nucleic acids may be present in whole cells, in a cell lysate, or in a partially purified or substantially pure form. A nucleic acid is "isolated" or "rendered substantially pure" when purified away from other cellμlar components or other contaminants, e.g., other cellμlar nucleic acids or proteins, by standard techniques, including alKaline/SDS treatment, CsCl banding, column chromatography, agarose gel electrophoresis and others well KNOwn in the art. See, F. Ausubel, et al., ed. (1987) Current Protocols in Molecμlar Biology, Greene Publishing and Wiley Interscience, New YorK. A nucleic acid according to at least some embodiments of the invention can be, for EXAMPLE, DNA or RNA and may or may not contain intronic sequences. In a preferred embodiment, the nucleic acid is a cDNA molecμle. [00366] Nucleic acids according to at least some embodiments of the invention can be obtained using standard molecμlar biology techniques. For antibothes expressed by hybridomas (e.g., hybridomas prepared from transgenic mice carrying human immunogloulin genes as described further below), cDNAs encoding the light and heavy chains of the antibody made by the hybridoma can be obtained by standard PCR amμlification or cDNA cloning techniques. For antibothes obtained from an immunogloulin gene library (e.g., using phage disμlay techniques), nucleic acid encoding the antibody can be recovered from the library. [00367] Once DNA fragments encoding VH and VL segments are obtained, these DNA fragments can be further manipplated by standard recombinant DNA techniques, for EXAMPLE to convert the variable region genes to fμll-length antibody chain genes, to Fab fragment genes or to a scFv gene. In these manipμlations, a VL- or VH-encoding DNA fragment is operatively linKed to another DNA fragment encoding another protein, such as an antibody constant region or a flexible linKer. [00368] The term "operatively linKed", as used in this context, is intended to mean that the two DNA fragments are joined such that the amino acid sequences encoded by the two DNA fragments remain in-frame. [00369] The isolated DNA encoding the VH region can be converted to a fμll-length heavy chain gene by operatively linKing the VH-encoding DNA to another DNA molecμle encoding heavy chain constant regions (CHI, CH2 and CH3). The sequences of human heavy chain constant region genes are KNOwn in the art (see e.g., Kabat, E. A., el al. (1991) Sequences of Proteins of ImmuNOlogical Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication NO. 91-3242) and DNA fragments encompassing these regions can be obtained by standard PCR amμlification. The heavy chain constant region can be an IgGl, IgG2, IgG3, IgG4, IgA, IgE, IgM or IgD constant region. For a Fab fragment heavy chain gene, the VH-encoding DNA can be operatively linKed to another DNA molecμle encoding only the heavy chain CHI constant region. [00370] The isolated DNA encoding the VL region can be converted to a fμll-length light chain gene (as well as a Fab light chain gene) by operatively linKing the VL-encoding DNA to another DNA molecμle encoding the light chain constant region, CL. The sequences of human light chain constant region genes are KNOwn in the art (see e.g., Kabat, E. A., et al. (1991) Sequences of Proteins of ImmuNOlogical Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication NO. 91-3242) and DNA fragments encompassing these regions can be obtained by standard PCR amμlification. The light chain constant region can be a Kappa or lambda constant region, [00371] To create a scFv gene, the VH- and VL-encoding DNA fragments are operatively linKed to another fragment encoding a flexible linKer, e.g., encoding the amino acid sequence (Gly4-Ser)3, such that the VH and VL sequences can be expressed as a contiguous single-chain protein, with the VL and VH regions joined by the flexible linKer (see e.g., Bird et al. (1988) Science 242:423-426; Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883; McCafferty et al., (1990) Nature 348:552-554). [00372] Production Of Anli-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti- FAM70A, Anti-TMEM154 monoclonal Antibothes [00373] monoclonal antibothes (mAbs) according to at least some embodiments of the present invention can be produced by a variety of techniques, including conventional monoclonal antibody methodology e.g., the standard somatic cell hybridization technique of Kohler and Milstein (1975) Nature 256:495. Although somatic cell hybridization procedures are preferred, in princiμle, other techniques for producing monoclonal antibody can be emμloyed e.g., viral or oncogenic transformation of B lymphocytes. [00374] A preferred animal system for preparing hybridomas is the murine system, Hybridoma production in the mouse is a very well-established procedure. Immunization protocols and techniques for isolation of immunized sμleNOcytes for fusion are KNOwn in the art. Fusion partners (e.g., murine myeloma cells) and fusion procedures are also KNOwn. [00375] Chimeric or humanized antibothes according to at least some embodiments of the present invention can be prepared based on the sequence of a murine monoclonal antibody prepared as described above. DNA encoding the heavy and light chain immunogloulins can be obtained from the murine hybridoma of interest and engineered to contain non-murine (e.g.,. human) immunogloulin sequences using standard molecμlar biology techniques. For EXAMPLE, to create a chimeric antibody, the murine variable regions can be linKed to human constant regions using mediods KNOwn in the art (see e.g., U.S. Pat. NO. 4,816,567 to Cabilly et al.). To create a humanized antibody, the murine CDR regions can be inserted into a human frameworK using methods KNOwn in the art (see e.g., U.S. Pat. NO. 5,225,539 to Winter, and U.S. Pat. NOs. 5,530,101; 5,585,089; 5,693,762 and 6,180,370 to Queen et al.). [00376] In a preferred embodiment, the antibothes according to at least some embodiments of the invention are human monoclonal antibothes. Such human monoclonal antibothes directed against KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 can be generated using transgenic or transchromosomic mice carrying parts of the human immune system rather than the mouse system. These transgenic and transchromosomic mice include mice referred to herein as the HuMAb Mouse RTM and KM Mouse, RTM. respectively, and are collectively referred to herein as "human Ig mice." The HuMAb Mouse TM, (Medarex. Inc.) contains human immunogloulin gene miniloci that encode unrearranged human heavy (.mu, and.gamma.) and.Kappa. light chain immunogloulin sequences, together with targeted mutations that inactivate the endogeNOus.mu. and.Kappa. chain loci (see e.g., Lonberg, et al. (1994) Nature 368(6474): 856-859). Accordingly, the mice exhibit reduced expression of mouse IgM or.Kappa., and in response to immunization, the introduced human heavy and light chain transgenes undergo class switching and somatic mutation to generate high affinity human IgGKappa. monoclonal (Lonberg, N. et al, (1994), supra; reviewed in Lonberg, N. (1994) HandbooK of Experimental Pharmacology 113:49- 101; Lonberg, N. and Huszar, D. (1995) Intern. Rev. ImmuNOl. 13: 65-93, and Harding, F. and Lonberg, N. (1995) Ann. N.Y. Acad. Sci. 764:536-546).

WO 01/14424 to Korman et al. [00377] In another embodiment, human antibothes according to at least some embodiments of the invention can be raised using a mouse that carries human immunogloulin sequences on transgenes and transchomosomes, such as a mouse that carries a human heavy chain transgene and a human light chain transchromosome. Such mice, referred to herein as "KM mice TM.", are described in detail in PCT Publication WO 02/43478 to Ishida et al. [00378] Still further, alternative transgenic animal systems expressing human immunogloulin genes are available in the art and can be used to raise anti- KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antibothes according to at least some embodiments of the invention. For EXAMPLE, an alternative transgenic system referred to as the XeNOmouse (Abgenix, Inc.) can be used; such mice are described in, for EXAMPLE, U.S. Pat. NOs. 5,939,598; 6,075,181; 6,114,598; 6,150,584 and 6,162,963 to Kucherlapati et al. [00379] Moreover, alternative transchromosomic animal systems expressing human immunogloulin genes are available in the art and can be used to raise Anti-KRTCAP3, Anti-FAM26F, Anti-MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes according to at least some embodiments of the invention, For EXAMPLE, mice carrying both a human heavy chain transchromosome and a human light chain transchromosome, referred to as "TC mice" can be used; such mice are described in TomizuKa et al. (2000) Proc. Natl. Acad Sci. USA 97:722-727. Furthermore, cows carrying human heavy and light chain transchromosomes have been described in the art (Kuroiwa et al. (2002) Nature BiotechNOlogy 20:889-894) and can be used to raise Anti-KRTCAP3, Anti-FAM26F, Anti- MGC52498, Anti-FAM70A, Anti-TMEM154 antibothes according to at least some embodiments of the invention, [00380] Human monoclonal antibothes according to at least some embodiments of the invention can also be prepared using phage^disμlay methods for screening libraries of human immunogloulin genes. Such phage disμlay methods for isolating human antibothes are established in the art. See for EXAMPLE: U.S. Pat. NOs. 5,223,409; 5,403,484; and 5,571,698 to Ladner et al.; U.S. Pat. NOs. 5,427,908 and 5,580,717 to Dower et al.; U.S. Pat. NOs. 5,969,108 and 6,172,197 to McCafferty et al.; and U.S. Pat. NOs. 5,885,793; 6,521,404; 6,544,73 1; 6,555,313; 6,582,915 and 6,593,081 to Griffiths et al. [00381] Human monoclonal antibothes according to at least some embodiments of the invention can also be prepared using SCID mice into which human immune cells have been reconstituted such that a human antibody response can be generated upon immunization. Such mice are described in, for EXAMPLE, U.S. Pat. NOs. 5,476,996 and 5,698,767 to Wilson etal. [00382] IMMUNIZATION OF HUMAN IG MICE [00383] When human Ig mice are used to raise human antibothes according to at least some embodiments of the invention, such mice can be immunized with a purified or enriched preparation of KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen and/or recombinant KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154, or an KRTCAP3, FAM26F, MGC52498, FAM70A, orTMEM154 fusion protein, as described by Lonberg, N. et al. (1994) Nature 368(6474): 856-859; Fishwild, D. et al. (1996) Nature BiotechNOlogy 14: 845-851; and PCT Publication WO 98/24884 and WO 01/14424. Preferably, the mice will be 6-16 weeKs of age upon the first infusion. For EXAMPLE, a purified or recombinant preparation (5-50.mu.g) of KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen can be used to immunize the human Ig mice intraperitoneally, [00384] Prior experience with various antigens by others has shown that the transgenic mice respond when initially immunized intraperitoneally (IP) with antigen in comμlete Freund's adjuvant, followed by every other weeK IP immunizations (up to a total of 6) with antigen in incomμlete Freund's adjuvant. However, adjuvants other than Freund's are also found to be effective. In addition, whole cells in the absence of adjuvant are found to be highly immuNOgenic. The immune response can be monitored over the course of the immunization protocol with μlasma samμles being obtained by retroorbital bleeds. The μlasma can be screened by ELISA (as described below), and mice with sufficient titers of anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti-TMEM154 human immunogloulin can be used for fusions. Mice can be boosted intraveNOusly with antigen 3 days before sacrifice and removal of the sμleen. It is expected that 2-3 fusions for each immunization may need to be performed. Between 6 and 24 mice are typically immunized for each antigen. Usually both HCo7 and HCol2 strains are used. In addition, both HCo7 and HCol2 transgene can be bred together into a single mouse having two different human heavy chain transgenes (HCo7/HCo 12). Alternatively or additionally, the KM Mouse. RTM. strain can be used. [00385] GENERATION OF HYBRIDOMAS PRODUCING HUMAN monoclonal ANTIBOtheS [00386] To generate hybridomas producing human monoclonal antibothes according to at least some embodiments of the invention, sμleNOcytes and/or lymph NOde cells from immunized mice can be isolated and fused to an appropriate immortalized cell line, such as a mouse myeloma cell line. The resμlting hybridomas can be screened for the production of antigen-specific antibothes. For EXAMPLE, single cell suspensions of sμlenic lymphocytes from immunized mice can be fused to one-sixth the number of P3X63-Ag8.653 nonsecreting mouse myeloma cells (ATCC, CRL 1580) with 50% PEG. Cells are plated at approximately 2 X 10 -5 in flat bottom microtiter plate, followed by a two weeK incubation in selective medium containing 20% fetal Clone Serum, 18% "653" conditioned media, 5% origen (IGEN), 4 mM L-glutamine, 1 mM sodium pyruvate, 5 mM HEPES, 0.055 mM 2- mercaptoethaNOl, 50 units/ml penicillin, 50 mg/ml streptomycin, 50 mg/ml gentamycin and IX HAT (Sigma; the HAT is added 24 hours after the fusion). After approximately two weeKs, cells can be cμltured in medium in which the HAT is reμlaced with HT, Individual wells can then be screened by ELISA for human monoclonal IgM and IgG antibothes. Once extensive hybridoma growth occurs, medium can be observed usually after 10-14 days. The antibody secreting hybridomas can be replated, screened again, and if still positive for human IgG, the monoclonal antibothes can be subcloned at least twice by limiting dilution. The stable subclones can then be cμltured in vitro to generate small amounts of antibody in tissue cμlture medium for characterization. [00387] To purify human monoclonal antibothes, selected hybridomas can be grown in two-liter spinner-flasKs for monoclonal antibody purification. Supernatants can be filtered and concentrated before affinity chromatography with protein A-Sepharose (Pharmacia, Piscataway, N.J.). Eluted IgG can be checKed by gel electrophoresis and high performance liquid chromatography to ensure purity. The buffer solution can be exchanged into PBS, and the concentration can be determined by OD280 using 1.43 extinction coefficient. The monoclonal antibothes can be aliquoted and stored at -80 degrees C. [003881 GENERATION OF TRANSFECTOMAS PRODUCING monoclonal ANTIBOtheS [00389] Antibothes according to at least some embodiments of the invention also can be produced in a host cell transfectoma using, for EXAMPLE, a combination of recombinant DNA techniques and gene transfection methods as is well KNOwn in the art (e.g., Morrison, S. (1985) Science 229:1202). [00390] For EXAMPLE, to express the antibothes, or antibody fragments thereof, DNAs encoding partial or fμll-length light and heavy chains, can be obtained by standard molecμlar biology techniques (e.g., PCR amμlification or cDNA cloning using a hybridoma that expresses the antibody of interest) and the DNAs can be inserted into expression vectors such that the genes are operatively linKed to transcriptional and translational control sequences. In this context, the term "operatively linKed" is intended to mean that an antibody gene is Hgated into a vector such that transcriptional and translational control sequences within the vector serve their intended function of regplating the transcription and translation of the antibody gene. The expression vector and expression control sequences are chosen to be compatible with the expression host cell used. The antibody light chain gene and the antibody heavy chain gene can be inserted into separate vector or, more typically, both genes are inserted into the same expression vector. The antibody genes are inserted into the expression vector by standard methods (e.g., ligation of comμlementary restriction sites on the antibody gene fragment and vector, or blunt end ligation if NO restriction sites are present). The light and heavy chain variable regions of the antibothes described herein can be used to create fμll-length antibody genes of any antibody isotype by inserting them into expression vectors already encoding heavy chain constant and light chain constant regions of the desired isotype such that the VH segment is operatively linKed to the CH segments within the vector and the VK segment is operatively linKed to the CL segment within the vector. Additionally or alternatively, the recombinant expression vector can encode a signal peptide that facilitates secretion of the antibody chain from a host cell. The antibody chain gene can be cloned into the vector such that the signal peptide is linKed in-frame to the amino terminus of the antibody chain gene. The signal peptide can be an immunogloulin signal peptide or a heterologous signal peptide (i.e., a signal peptide from a non-immunogloulin protein). [00391] In addition to the antibody chain genes, the recombinant expression vectors according to at least some embodiments of the invention carry regμlatory sequences that control the expression of the antibody chain genes in a host cell. The term "regμlatory sequence" is intended to include promoters, enhancers and other expression control elements (e.g., polyadenylation signals) that control the transcription or translation of the antibody chain genes. Such regμlatory sequences are described, for EXAMPLE, in Goeddel (Gene Expression TechNOlogy. Methods in Enzymology 185, Academic Press, San thego, Calif. (1990)). It will be appreciated by those sKilled in the art that the design of the expression vector, including the selection of regμlatory sequences, may depend on such factors as the choice of the host cell to be transformed, the level of expression of protein desired, etc. Preferred regμlatory sequences for mammalian host cell expression include viral elements that direct high levels of protein expression in mammalian cells, such as promoters and/or enhancers derived from cytomegalovirus (CMV), Simian Virus 40 (SV40), adenovirus, (e.g., the adenovirus major late promoter (AdMLP) and polyoma. Alternatively, nonviral regμlatory sequences may be used, such as the ubiquitin promoter or.beta.-globin promoter. Still further, regμlatory elements composed of sequences from different sources, such as the SR alpha, promoter system, which contains sequences from the SV40 early promoter and the long terminal repeat of human T cell leuKemia virus type 1 (TaKebe, Y. et al. (1988) Mol, Cell. Biol. 8:466-472). 100392] In addition to the antibody chain genes and regμlatory sequences, the recombinant expression vectors according to at least some embodiments of the invention may carry additional sequences, such as sequences that regplate reμlication of the vector in host cells (e.g., origins of reμlication) and selectable marKer genes. The selectable marKer gene facilitates selection of host cells into which the vector has been introduced (see, e.g., U.S. Pat. NOs. 4,399,216, 4,634,665 and 5,179,017, all by Axel et al.). For EXAMPLE, typically the selectable marKer gene confers resistance to drugs, such as G418, hygromycin or methotrexate, on a host cell into which the vector has been introduced, Preferred selectable marKer genes include the dihydrofolate reductase (DHFR) gene (for use in dhfr- host cells with methotrexate selection/amμlification) and the neo gene (for G418 selection). [00393] For expression of the light and heavy chains, the expression vectors encoding the heavy and light chains is transfected into a host cell by standard techniques, The various forms of the term "transfection" are intended to encompass a wide variety of techniques commonly used for the introduction of exogeNOus DNA into a proKaryotic or euKaryotic host cell, e.g., electroporation, calcium-phosphate precipitation, DEAE-dextran transfection and the liKe. Although it is theoretically possible to express the antibothes according to at least some embodiments of the invention in either proKaryotic or euKaryodc host cells, expression of antibothes in euKaryotic cells, and most preferably mammalian host cells, is the most preferred because such euKaryotic cells, and in particμlar mammalian cells, are more liKely than proKaryotic cells to assemble and secrete a properly folded and immuNOlogically active antibody. ProKaryotic expression of antibody genes has been reported to be ineffective for production of high yields of active antibody (Boss, M. A. and Wood, C. R. (1985) ImmuNOlogy Today 6:12-13). [00394] Preferred mammalian host cells for expressing the recombinant antibothes according to at least some embodiments of the invention include Chinese Hamster Ovary (CHO cells) (including dhfr- CHO cells, described in Urlaub and Chasin, (1980) Proc. Natl. Acad. Sci. USA 77:4216-4220, used with a DHFR selectable marKer, e.g., as described in R. J. Kaufman and P. A. Sharp (1982) Mol. Biol. 159:601-621), NSO myeloma cells, COS cells and SP2 cells. In particμlar, for use with NSO myeloma cells, another preferred expression system is the GS gene expression system disclosed in WO 87/04462, WO 89/01036 and EP 338,841. When recombinant expression vectors encoding antibody genes are introduced into mammalian host cells, the antibothes are produced by cμlturing the host cells for a period of time sufficient to allow for expression of the antibody in the host cells or, preferably, secretion of the antibody into the cμlture medium in which the host cells are grown. Antibothes can be recovered from the cμlture medium using standard protein purification methods. [00395] CHARACTERIZATION OF ANTIBODY BINDING TO ANTIGEN [00396] Antibothes according to at least some embodiments of the invention can be tested for binding to KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 by, for EXAMPLE, standard ELISA. Briefly, microtiter plates are coated with purified KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 at 0.25.mu.g/ml in PBS, and then blocKed with 5% bovine serum albumin in PBS. Dilutions of antibody (e.g., dilutions of μlasma from KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154-immunized mice) are added to each well and incubated for 1-2 hours at 37 degrees C, The plates are washed with PBS/Tween and then incubated with secondary reagent (e.g., for human antibothes, a goat- anti-human IgG Fc-specific polyclonal reagent) conjugated to alKaline phosphatase for 1 hour at 37 degrees C. After washing, the plates are developed with pNPP substrate (1 mg/ml), and analyzed at OD of 405-650. Preferably, mice which develop the highest titers will be used for fusions. [00397] An ELISA assay as described above can also be used to screen for hybridomas that show positive reactivity with KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 immuNOgen. Hybridomas that bind with high avidity to KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 are subcloned and further characterized. One clone from each hybridoma, which retains the reactivity of the parent cells (by ELISA), can be chosen for maKing a 5-10 vial cell banK stored at -140 degrees C„ and for antibody purification. [00398] To purify anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti-TMEM154 antibothes, selected hybridomas can be grown in two-liter spinner-flasKs for monoclonal antibody purification, Supernatants can be filtered and concentrated before affinity chromatography with protein A-sepharose (Pharmacia, Piscataway, N.J.). Eluted IgG can be checKed by gel electrophoresis and high performance liquid chromatography to ensure purity. The buffer solution can be exchanged into PBS, and the concentration can be determined by OD280 using 1.43 extinction coefficient. The monoclonal antibothes can be aliquoted and stored at -80 degrees C. [00399] To determine if the selected anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti-TMEM154 monoclonal antibothes bind to unique epitopes, each antibody can be biotinylated using commercially available reagents (Pierce, RocKford, 111.). Competition stuthes using unlabeled monoclonal antibothes and biotinylated monoclonal antibothes can be performed using KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 coated-ELISA plates as described above. Biotinylated mAb binding can be detected with a strep-avidin-alKaline phosphatase probe. [00400] To determine the isotype of purified antibothes, isotype ELISAs can be performed using reagents specific for antibothes of a particμlar isotype. For EXAMPLE, to determine the isotype of a human monoclonal antibody, wells of microtiter plates can be coated with l.mu.g/ml of anti-human immunogloulin overnight at 4 degrees C. After blocKing with 1% BSA, the plates are reacted with lmug /ml or less of test monoclonal antibothes or purified isotype controls, at ambient temperature for one to two hours. The wells can then be reacted with either human IgGl or human IgM-specific alKaline phosphatase-conjugated probes. plates are developed and analyzed as described above. [00401] Anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti- TMEM154 human IgGs can be further tested for reactivity with KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen, respectively, by Western blotting. Briefly, KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen can be prepared and subjected to sodium dodecyl sμlfate polyacrylamide gel electrophoresis. After electrophoresis, the separated antigens are transferred to nitrocellμlose membranes, blocKed with 10% fetal calf serum, and probed with the monoclonal antibothes to be tested. Human IgG binding can be detected using anti-human IgG alKaline phosphatase and developed with BCIP/NBT substrate tablets (Sigma Chem. Co., St. Louis, Mo.). [00402] CONJUGATES OR IMMUNOCONJUGATES [00403] According to at least some embodiments, the present invention features immuNOconjugates comprising an anti-KRTCAF3, anti-FAM26F, anti-MGC52498, anti- FAM70A, or anti-TMEM154 antibody, or a fragment thereof, conjugated to a therapeutic moiety, such as a cytotoxin, a drug (e.g., an immuNOsuppressant) or a radiotoxin. Such conjugates are referred to herein as "immuNOconjugates". ImmuNOconjugates that include one or more cytotoxins are referred to as "immunotoxins." A cytotoxin or cytotoxic agent includes any agent that is detrimental to (e.g., Kills) cells. EXAMPLEs include taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, teNOposide, vincristine, vinblastine, colchicin, doxorubicin, dauNOrubicin, dihydroxy anthracin dione, mitoxantrone, mithramycin, actiNOmycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propraNOlol, and puromycin and analogs or homologs thereof. Therapeutic agents also include, for EXAMPLE, antimetabolites (e.g., methotrexate, 6-mercaptopurine, 6-thioguanine, cytarabine, 5-fluorouracil decarbazine), alKylating agents (e.g., mechlorethamine, thioepa chlorambucil, melphalan, carmustine (BSNU) and lomustine (CCNU), cyclothosphamide, busμlfan, dibromomanrutol, streptozotocin, mitomycin C, and cis-dichlorodiamine μlatinum (II) (DDP) cisμlatin), anthracyclines (e.g., dauNOrubicin (formerly dauNOmycin) and doxorubicin), antibiotics (e.g., dacriNOmycin (formerly actiNOmycin), bleomycin, mithramycin, and anthramycin (AMC)), and anti-mitotic agents (e.g., vincristine and vinblastine). [00404] Other preferred EXAMPLEs of therapeutic cytotoxins that can be conjugated to an antibody according to at least some embodiments of the invention include duocarmycins, calicheamicins, maytansines and auristatins, and derivatives thereof. An EXAMPLE of a calicheamicin antibody conjugate is commercially available (Mylotarg.TM.; Wyeth). [00405] Cytotoxins can be conjugated to antibothes according to at least some embodiments of the invention using linKer techNOlogy available in the art. EXAMPLEs of linKer types that have been used to conjugate a cytotoxin to an antibody include, but are not limited to, hydrazones, thioethers, esters, disμlfides and peptide-containing linKers. A linKer can be chosen that is, for EXAMPLE, susceptible to cleavage by low pH within the lysosomal compartment or susceptible to cleavage by proteases, such as proteases preferentially expressed in tumor tissue such as cathepsins (e.g., cathepsins B, C, D). [00406] For further discussion of types of cytotoxins, linKers and methods for conjugating therapeutic agents to antibothes, see also Saito, G. et al. (2003) Adv. Drug Deliv.

[00407] Antibothes according to at least some embodiments of the present invention also can be conjugated to a radioactive isotope to generate cytotoxic radiopharmaceuticals, also referred to as radioimmuNOconjugates. EXAMPLEs of radioactive isotopes that can be conjugated to antibothes for use diagNOstically or therapeutically include, but are not limited to, iodine 131, indium 111, yttrium 90 and lutetium 177. Method for preparing radioimmunconjugates are established in the art. EXAMPLEs of radioimmuNOconjugates are commercially available, including Zevalin.TM. (IDEC Pharmaceuticals) and Bexxar.TM. (Corixa Pharmaceuticals), and similar methods can be used to prepare radioimmuNOconjugates using the antibothes according to at least some embodiments of the invention. [00408] The antibody conjugates according to at least some embodiments of the invention can be used to modify a given biological response, and the drug moiety is not to be construed as limited to classical chemical therapeutic agents. For EXAMPLE, the drug moiety may be a protein or polypeptide possessing a desired biological activity. Such proteins may include, for EXAMPLE, an enzymatically active toxin, or active fragment thereof, such as abrin, ricin A, pseudomonas exotoxin, or diphtheria toxin; a protein such as tumor necrosis factor or interferon-.gamma.; or, biological response modifiers such as, for EXAMPLE, lymphoKines, interleuKin-1 ("IL-1"), interleuKin-2 ("IL-2"), interleuKin-6 ("IL-6"), granμlocyte macrophage colony stimplating factor ("GM-CSF"), granμlocyte colony stimplating factor ("G-CSF"), or other growth factors. [00409] Techniques for conjugating such therapeutic moiety to antibothes are well KNOwn, see, e.g., Arnon et al., "monoclonal Antibothes For Immunotargeting Of Drugs In Cancer Therapy", in monoclonal Antibothes And Cancer Therapy, Reisfeld et al. (eds.), pp. 243-56 (Alan R. Liss, Inc. 1985); Hellstrom et al., "Antibothes For Drug Delivery", in Controlled Drug Delivery (2nd Ed.), Robinson et al. (eds.), pp. 623-53 (Marcel DeKKer, Inc. 1987); Thorpe, "Antibody Carriers Of Cytotoxic Agents In Cancer Therapy: A Review", in monoclonal Antibothes '84: Biological And Clinical Apμlications, Pinchera et al.

Rev., 62:119-58 (1982). [00410] BISPECIFIC MOLECμlES [00411] In another aspect, the present invention features bispecific molecμles comprising an anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti-TMEM154 antibody, or a fragment thereof, according to at least some embodiments of the invention. An antibody according to at least some embodiments of the invention, or antigen-binding portions thereof, can be derivatized or linKed to another functional molecμle, e.g., another peptide or protein (e.g., another antibody or ligand for a receptor) to generate a bispecific molecμle that binds to at least two different binding sites or target molecμles. The antibody according to at least some embodiments of the invention may in fact be derivatized or linKed to more than one other functional molecμle to generate mμltispecific molecμles that bind to more than two different binding sites and/or target molecμles; such mμltispecific molecμles are also intended to be encompassed by the term "bispecific molecμle" as used herein. To create a bispecific molecμle according to at least some embodiments of the invention, an antibody according to at least some embodiments of the invention can be functionally linKed (e.g., by chemical couμling, genetic fusion, noncovalent association or otherwise) to one or more other binding molecμles, such as another antibody, antibody fragment, peptide or binding mimetic, such that a bispecific molecμle resμlts, [00412] Accordingly, the present invention includes bispecific molecμles comprising at least one first binding specificity for a KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide and a second binding specificity for a second target epitope. In a particμlar embodiment according to at least some embodiments of the invention, the second target epitope is an Fc receptor, e.g., human Fc gamma RI (CD64) or a human Fc alpha receptor (CD89). Therefore, the invention includes bispecific molecμles capable of binding both to Fc gamma. R, Fc alpha R or Fc epsilon R expressing effector cells (e.g., moNOcytes, macrophages or polymorphonuclear cells (PMNs)), and to target cells expressing a KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide, respectively. These bispecific molecμles target KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide expressing cells to effector cell and trigger Fc receptor-mediated effector cell activities, such as phagocytosis of KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide expressing cells, antibody dependent cell-mediated cytotoxicity (ADCC), cytoKine release, or generation of superoxide anion. [00413] In an embodiment according to at least some embodiments of the invention in which the bispecific molecμle is mμltispecific, the molecμle can further include a third binding specificity, in addition to an anti-Fc binding specificity and an anti-6f binding specificity. In one embodiment, the third binding specificity is an anti-enhancement factor (EF) portion, e.g., a molecμle which binds to a surface protein involved in cytotoxic activity and thereby increases the immune response against the target cell, [00414] The " anti-enhancement factor portion" can be an antibody, functional antibody fragment or a Ugand that binds to a given molecμle, e.g., an antigen or a receptor, and thereby resμlts in an enhancement of the effect of the binding determinants for the Fc receptor or target cell antigen. The "anti-enhancement factor portion" can bind an Fc receptor or a target cell antigen. Alternatively, the anti-enhancement factor portion can bind to an entity that is different from the entity to which the first and second binding specificities bind. For EXAMPLE, the anti-enhancement factor portion can bind a cytotoxic T- cell (e.g., via CD2, CD3, CD8, CD28, CD4, CD40, ICAM-1 or other immune cell that resμlts in an increased immune response against the target cell). [00415] In one embodiment, the bispecific molecμles according to at least some embodiments of the invention comprise as a binding specificity at least one antibody, or an antibody fragment thereof, including, e.g., an Fab, Fab', F(ab')2, Fv, or a single chain Fv. The antibody may also be a light chain or heavy chain dimer, or any minimal fragment thereof such as a Fv or a single chain construct as described in Ladner et al. U.S. Pat. NO. 4,946,778, the contents of which is expressly incorporated by reference. [00416] The production and characterization of certain preferred anti-Fc gamma, monoclonal antibothes are described by Fanger et al. in PCT Publication WO 88/00052 and in U.S. Pat. NO. 4,954,617, the teachings of which are fμlly incorporated by reference herein. These antibothes bind to an epitope of Fc Rl, FcyRII or FcyRIII at a site which is distinct from the Fc binding site of the receptor and, thus, their binding is not blocKed substantially by physiological levels of IgG. Specific anti-Fc RI antibothes useful in this invention are mAb 22, mAb 32, mAb 44, mAb 62 and mAb 197. The hybridoma producing mAb 32 is available from the American Type Cμlture Collection, ATCC Accession NO. HB9469. In other embodiments, the anti-Fey receptor antibody is a humanized form of monoclonal antibody 22 (H22), The production and characterization of the H22 antibody is described in GraziaNO, R.F. et al. (1995) J. ImmuNOl. 155 (10): 4996-5002 and PCT Publication WO 94/10332. The H22 antibody producing cell line is deposited at the American Type Cμlture Collection under the designation HA022CLI and has the accession NO. CRL 11177. [00417] In still other preferred embodiments, the binding specificity for an Fc receptor is provided by an antibody that binds to a human IgA receptor, e.g., an Fc-alpha receptor (Fc alpha RI(CD89)), the binding of which is preferably not blocKed by human immunogloulin A (IgA). The term "IgA receptor" is intended to include the gene product of one alpha.-gene (Fc alpha RI) located on chromosome 19. This gene is KNOwn to encode several alternatively sμliced transmembrane isoforms of 55 to 10 KDa. [00418] Fc alpha RI (CD89) is constitutively expressed on moNOcytes/macrophages, eosiNOphilic and neutrophilic granμlocytes, but not on non-effector cell popμlations. Fc alpha RI has medium affinity (Approximately 5X10-7 M-l) for both IgAl and IgA2, which is increased upon exposure to cytoKines such as G-CSF or GM-CSF (Morton, H. C. et al. (1996) Critical Reviews in ImmuNOlogy 16:423-440). Four Fca Rl-specific monoclonal antibothes, identified as A3, A59, A62 and A77, which bind Fc alpha RI outside the IgA ligand binding domain, have been described (Monteiro, R. C. et al. (1992) J. ImmuNOl. 148:1764). [00419] Fc alpha RI and Fc gamma RI are preferred trigger receptors for use in the bispecific molecμles according to at least some embodiments of the invention because they are (1) expressed primarily on immune effector cells, e.g., moNOcytes, PMNs, macrophages and dendritic cells; (2) expressed at high levels (e.g., 5,000-100,000 per cell); (3) mediators of cytotoxic activities (e.g., ADCC, phagocytosis); (4) mediate enhanced antigen presentation of antigens, including self-antigens, targeted to them. [00420] While human monoclonal antibothes are preferred, other antibothes which can be emμloyed in the bispecific molecμles according to at least some embodiments of the invention are murine, chimeric and humanized monoclonal antibothes. [00421] The bispecific molecμles according to at least some embodiments of the present invention can be prepared by conjugating the constituent binding specificities, e.g., the anti- FcR and anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A, or anti- TMEM154 polypeptide binding specificities, using methods KNOwn in the art. For EXAMPLE, each binding specificity of the bispecific molecμle can be generated separately and then conjugated to one another. When the binding specificities are proteins or peptides, a variety of couμling or cross-linKing agents can be used for covalent conjugation. EXAMPLEs of cross-linKing agents include protein A, carbodiimide, N-succinimidyl-S-acetyl-thioacetate (SATA), 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB), o-phenylenedimaleimide (oPDM), N- succimmidyl-3-(2-pyridyld- ithio)propionate (SPDP), and sμlfosuccinimidyl 4-(N- maleimidomethyl) cyclohaxane-1-carboxylate (sμlfo-SMCC) (see e.g., KarpovsKy et al. (1984) J. Exp. Med. 160:1686; Liu, M A et al. (1985) Proc. Natl. Acad. Sci. USA 82:8648). Other methods include those described in Paμlus (1985) Behring Ins. Mitt. NO. 78, 118-132; Brennan et al. (1985) Science 229:81-83), and Glennie et al. (1987) J. ImmuNOl. 139: 2367- 2375). Preferred conjugating agents are SATA and sμlfo-SMCC, both available from Pierce Chemical Co. (RocKford, HI.). [00422] When the binding specificities are antibothes, they can be conjugated via sμlfhydryl bonding of the C-terminus hinge regions of the two heavy chains. In a particμlarly preferred embodiment, the hinge region is modified to contain an odd number of sμlfhydryl residues, preferably one, prior to conjugation. [00423] Alternatively, bom binding specificities can be encoded in the same vector and expressed and assembled in the same host cell. This method is particμlarly useful where the bispecific molecμle is a mAbXmAb, mAbXFab, FabXF(ab')2 or ligandXFab fusion protein. A bispecific molecμle according to at least some embodiments of the invention can be a single chain molecμle comprising one single chain antibody and a binding determinant, or a single chain bispecific molecμle comprising two binding determinants, Bispecific molecμles may comprise at least two single chain molecμles. Methods for preparing bispecific molecμles are described for EXAMPLE in U.S. Pat. NO. 5,260,203; U.S. Pat. NO. 5,455,030; U.S. Pat. NO. 4,881,175; U.S. Pat. NO. 5,132,405; U.S. Pat. NO. 5,091,513; U.S. Pat. NO. 5,476,786; U.S. Pat. NO. 5,013,653; U.S. Pat. NO. 5,258,498; and U.S. Pat. NO. 5,482,858. {00424] Binding of the bispecific molecμles to their specific targets can be confirmed by, for EXAMPLE, enzyme-linKed immuNOsorbent assay (ELISA), radioimmuNOassay (RIA), FACS analysis, bioassay (e.g., growth inhibition), or Western Blot assay. Each of these assays generally detects the presence of protein-antibody comμlexes of particμlar interest by emμloying a labeled reagent (e.g., an antibody) specific for the comμlex of interest. For EXAMPLE, the FcR-antibody comμlexes can be detected using e.g., an enzyme-linKed antibody or antibody fragment which recognizes and specifically binds to the antibody-FcR comμlexes. Alternatively, the comμlexes can be detected using any of a variety of other immuNOassays. For EXAMPLE, the antibody can be radioactively labeled and used in a radioimmuNOassay (RIA) (see, for EXAMPLE, Weintraub, B., Princiμles of RadioimmuNOassays, Seventh Training Course on Radioligand Assay Techniques, The Endocrine Society, March, 1986, which is incorporated by reference herein). The radioactive isotope can be detected by such means as the use of a gamma, counter or a scintillation counter or by autoradiography. [00425] PHARMACEUTICAL COMPOSITIONS [00426] In another aspect, the present invention provides a composition, e.g., a pharmaceutical composition, containing one or a combination of monoclonal antibothes, or antigen-binding portions thereof, according to at least some embodiments of the present invention, formplated together with a pharmaceutically acceptable carrier. Such compositions may include one or a combination of (e.g., two or more different) antibothes, or immuNOconjugates or bispecific molecμles according to at least some embodiments of the invention. For EXAMPLE, a pharmaceutical composition according to at least some embodiments of the invention can comprise a combination of antibothes (or immuNOconjugates or bispecifics) that bind to different epitopes on the target antigen or that have comμlementary activities. [00427] As discussed supra, at least some embodiments of the present invention further embrace identifying other molecμles such as small organic molecμles, peptides, ribozymes, carbohydrates, glycoprotein, siRNAs, antisense RNAs and the liKe which specifically bind and/or modplate (enhance or inhibit) an activity elicited by the KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 antigen or polypeptides, respectively. These molecμles may be identified by KNOwn screening methods such as binding assays. Typically these assays will be high throughput and will screen a large library of synthesized or native compounds in order to identify putative drug candidates that bind and/or modplate KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 related activities. [00428] Specifically, the invention embraces the development of drugs containing the ectodomain of the TMEM154 antigen or polypeptide, or a fragment or variant thereof or a corresponding nucleic acid sequence encoding. [00429] Thus, the present invention features a pharmaceutical composition comprising a therapeutically effective amount of a therapeutic agent according to the present invention. According to the present invention the therapeutic agent coμld be any one of TMEM154 ectodomain, or a fragment or a variant or a conjugate thereof, or a corresponding nucleic acid sequence encoding same. [00430] The pharmaceutical composition according to the present invention is further optionally used for the treatment of cancer and/or immune related conditions or disorders. [00431] The therapeutic agents according to at least some embodiments of the present invention can be provided to the subject alone, or as part of a pharmaceutical composition where they are mixed with a pharmaceutically acceptable carrier. [00432] Pharmaceutical compositions according to at least some embodiments of the invention also can be administered in combination therapy, i.e., combined with other agents. For EXAMPLE, the combination therapy can include an anti-KRTCAP3, anti-FAM26F, anti- MGC52498, anti-FAM70A, or anti-TMEM154 antibody or KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 modplating agent according to the present invention such as a soluble polypeptide conjugate containing the ectodomain of the TMEM154 polypeptide or a small molecμle such as a peptide, ribozyme, siRNA, or other drug mat binds a KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide, combined with at least one other therapeutic or immune modμlatory agent. [00433] A composition according to at least some embodiments of the present invention can be administered via one or more routes of administration using one or more of a variety of methods KNOwn in the art. As will be appreciated by the sKilled artisan, the route and/or mode of administration will vary depending upon the desired resμlts. Preferred routes of administration for antibothes according to at least some embodiments of the invention include intraveNOus, intramuscμlar, intradermal, intraperitoneal, subcutaneous, spinal or other parenteral routes of administration, for EXAMPLE by injection or infusion. The phrase "parenteral administration" as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intraveNOus, intramuscμlar, intraarterial, intrathecal, intracapsμlar, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticμlar, intraarticμlar, subcapsμlar, subarachNOid, intraspinal, epidural and intrasternal injection and infusion. [00434] As used herein, "pharmaceutically acceptable carrier" includes any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the liKe that are physiologically compatible. Preferably, the carrier is suitable for intraveNOus, intramuscμlar, subcutaneous, parenteral, spinal or epidermal administration (e.g., by injection or infusion). Depending on the route of administration, the active compound, i.e., antibody, immuNOconjugate, or bispecific molecμle, may be coated in a material to protect the compound from the action of acids and other natural conditions that may inactivate the compound. [00435] A pharmaceutical composition according to at least some embodiments of the invention also may include a pharmaceutically acceptable anti-oxidant. EXAMPLEs of pharmaceutically acceptable antioxidants include: (1) water soluble antioxidants, such as ascorbic acid, cysteine hydrochloride, sodium bisμlfate, sodium metabisμlfite, sodium sμlfite and the liKe; (2) oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, alpha- tocopherol, and the liKe; and (3) metal chelating agents, such as citric acid, ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the liKe. EXAMPLEs of suitable aqueous and nonaqueous carriers that may be emμloyed in the pharmaceutical compositions according to at least some embodiments of the invention include water, ethaNOl, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the liKe), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for EXAMPLE, by the use of coating materials, such as lecitirin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. [00436] These compositions may also contain adjuvants such as preservatives, wetting agents, emμlsifying agents and dispersing agents. Prevention of presence of microorganisms may be ensured both by sterilization procedures, supra, and by the inclusion of various antibacterial and antifungal agents, for EXAMPLE, paraben, chlorobutaNOl, pheNOl sorbic acid, and the liKe. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the liKe into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum moNOstearate and gelatin. [00437] Pharmaceutically acceptable carriers include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. The use of such media and agents for pharmaceutically active substances is KNOwn in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the pharmaceutical compositions according to at least some embodiments of the invention is contemplated. Supμlementary active compounds can also be incorporated into the compositions. [00438] Therapeutic compositions typically must be sterile and stable under the conditions of manufacture and storage. The composition can be formplated as a solution, microemμlsion, liposome, or other ordered structure suitable to high drug concentration. The carrier can be a solvent or dispersion medium containing, for EXAMPLE, water, ethaNOl, polyol (for EXAMPLE, glycerol, propylene glycol, and liquid polyethylene glycol, and the liKe), and suitable mixtures thereof. The proper fluidity can be maintained, for EXAMPLE, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. In many cases, it will be preferable to include isotonic agents, for EXAMPLE, sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent that delays absorption, for EXAMPLE, moNOstearate salts and gelatin. Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingrethents enumerated above, as required, followed by sterilization microfiltration. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingrethents from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying (lyophilization) that yield a powder of the active ingrethent μlus any additional desired ingrethent from a previously sterile-filtered solution thereof. [00439] Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingrethents enumerated above, as required, followed by sterilization microfiltration. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingrethents from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze- drying (lyophilization) that yield a powder of the active ingrethent μlus any additional desired ingrethent from a previously sterile-filtered solution thereof. [00440] The amount of active ingrethent which can be combined with a carrier material to produce a single dosage form will vary depending upon the subject being treated, and the particμlar mode of administration. The amount of active ingrethent which can be combined with a carrier material to produce a single dosage form will generally be that amount of the composition which produces a therapeutic effect. Generally, out of one hundred per cent, this amount will range from about 0.01 per cent to about ninety-nine percent of active ingrethent, optionally from about 0.1 per cent to about 70 per cent, optionally from about 1 per cent to about 30 per cent of active ingrethent in combination with a pharmaceutically acceptable carrier, [00441] Dosage regimens are adjusted to provide the optimum desired response (e.g., a therapeutic response). For EXAMPLE, a single bolus may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. It is especially advantageous to formplate parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subjects to be treated; each unit contains a predetermined quantity of active compound calcplated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms according to at least some embodiments of the invention are dictated by and directly dependent on (a) the unique characteristics of the active compound and the particμlar tiierapeutic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals. For administration of the antibody, the dosage ranges from about 0.0001 to 100 mg/Kg, and more usually 0.01 to 5 mg/Kg, of the host body weight. For EXAMPLE dosages can be 0.3 mg/Kg body weight, 1 mg/Kg body weight, 3 mg/Kg body weight, 5 mg/Kg body weight or 10 mg/Kg body weight or within the range of 1-10 mg/Kg. An exemμlary treatment regime entails administration once per weeK, once every two weeKs, once every three weeKs, once every four weeKs, once a month, once every 3 months or once every three to 6 months. [00442] Alternatively, antibody can be administered as a sustained release formμlation, in which case less frequent administration is required. Dosage and frequency vary depending on the half-life of the antibody in the patient. In general, human antibothes show the longest half life, followed by humanized antibothes, chimeric antibothes, and nonhuman antibothes. The dosage and frequency of administration can vary depending on whether the treatment is prophylactic or therapeutic. In prophylactic apμlications, a relatively low dosage is administered at relatively infrequent intervals over a long period of time. Some patients continue to receive treatment for the rest of their lives. In therapeutic apμlications, a relatively high dosage at relatively short intervals is sometimes required until progression of the disease is reduced or terminated, and preferably until the patient shows partial or comμlete amelioration of symptoms of disease. Thereafter, the patient can be administered a prophylactic regime. [00443] Actual dosage levels of the active ingrethents in the pharmaceutical compositions according to at least some embodiments of the present invention may be varied so as to obtain an amount of the active ingrethent which is effective to achieve the desired therapeutic response for a particμlar patient, composition, and mode of administration, without being toxic to the patient. The selected dosage level will depend upon a variety of pharmacoKinetic factors including the activity of the particμlar compositions according to at least some embodiments of the present invention emμloyed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion of the particμlar compound being emμloyed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particμlar compositions emμloyed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, and liKe factors well KNOwn in the medical arts. [00444] A "therapeutically effective dosage" of an anti-KRTCAP3, anti-FAM26F, anti- MGC52498, anti-FAM70A, or anti-TMEM154 antibody according to at least some embodiments of the invention preferably resμlts in a decrease in severity of disease symptoms, an increase in frequency and duration of disease symptom-free periods, an increase in lifespan, disease remission, or a prevention of impairment or disability due to the disease affliction. For EXAMPLE, for the treatment of KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 polypeptide positive tumors, e.g., ovarian tumors, lung tumors, breast tumors, colon tumors, Kidney tumors, liver tumors, pancreatic tumors, prostate cancer, melaNOma and hematological malignancies such as Mμltiμle Myeloma, lymphoma, non-HodgKin's lymphoma, anti CD20 (i.e. Rituximab) resistant lymphoma, leuKemia, T cell leuKemia, a "therapeutically effective dosage" optionally inhibits cell growth or tumor growth by at least about 20%, 40%, 60%, 80% relative to untreated subjects. The ability of a compound to inhibit tumor growth can be evaluated in an animal model system predictive of efficacy in human tumors. Alternatively, this property of a composition can be evaluated by examining the ability of the compound to inhibit, such inhibition in vitro by assays KNOwn to the sKilled practitioner. [00445] Alternatively or additionally, a "therapeutically effective dosage" preferably resμlts in at least stable disease, preferably partial response, more preferably comμlete response, as assessed by the WHO or RECIST criteria for tumor response (Natl Cancer Inst 1999;91:523-8 and Cancer 1981;47:207-14). [00446] A therapeutically effective amount of a therapeutic compound can decrease tumor size, or otherwise ameliorate symptoms in a subject, or otherwise support partial or comμlete stable disease and/or partial or comμlete response as determined above. One of ordinary sKill in the art woμld be able to determine such amounts based on such factors as the subject's size, the severity of the subject's symptoms, and the particμlar composition or route of administration selected. [00447] Therapeutic compositions can be administered with medical devices KNOwn in the art. For EXAMPLE, in a preferred embodiment, a therapeutic composition according to at least some embodiments of the invention can be administered with a needles hypodermic injection device, such as the devices disclosed in U.S. Pat. NOs. 5,399,163; 5,383,851; 5,312,335; 5,064,413; 4,941,880; 4,790,824; or 4,596,556. EXAMPLEs of well-KNOwn imμlants and modμles useful in the present invention include: U.S. Pat. NO, 4,487,603, which discloses an imμlantable micro-infusion pump for dispensing medication at a controlled rate; U.S. Pat. NO, 4,486,194, which discloses a therapeutic device for administering medicaments through the sKin; U.S. Pat. NO. 4,447,233, which discloses a medication infusion pump for delivering medication at a precise infusion rate; U.S. Pat, NO. 4,447,224, which discloses a variable flow imμlantable infusion apparatus for continuous drug delivery; U.S. Pat. NO. 4,439,196, which discloses an osmotic drug delivery system having mμlti-chamber compartments; and U.S. Pat, NO. 4,475,196, which discloses an osmotic drug delivery system. These patents are incorporated herein by reference. Many other such imμlants, delivery systems, and modμles are KNOwn to tfiose sKilled in the art. [00448] In certain embodiments, the antibothes or other KRTCAP3, FAM26F, MGC52498, FAM70A, or TMEM154 related drugs according to at least some embodiments of the invention can be formplated to ensure proper distribution in vivo. For EXAMPLE, the b100d-brain barrier (BBB) excludes many highly hydrophilic compounds. To ensure that the therapeutic compounds according to at least some embodiments of the invention cross the BBB (if desired), they can be formplated, for EXAMPLE, in liposomes. For methods of manufacturing liposomes, see, e.g., U.S. Pat. NOs. 4,522,811; 5,374,548; and 5,399,331. The liposomes may comprise one or more moieties which are selectively transported into specific cells or organs, thus enhance targeted drug delivery (see, e.g., V. V. Ranade (1989) J. Clin, Pharmacol. 29:685). Exemμlary targeting moieties include folate or biotin (see, e.g., U.S. Pat. NO. 5,416,016 to Low et al.); manNOsides (Umezawa et al., (1988) Biochem. Biophys. Res. Commun. 153:1038); antibothes (P. G. Bloeman et al. (1995) FEBS Lett. 357:140; M. Owais et al. (1995) Antimicrob. Agents Chemother. 39:180); surfactant protein A receptor (Briscoe et al. (1995) Am. J Physiol. 1233:134); μl20 (Schreier et al. (1994) J. Biol. Chem. 269:9090); see also K. Keinanen; M. L. LauKKanen (1994) FEBS Lett. 346:123; J. J. Killion; I. J. Fidler (1994) ImmuNOmethods 4:273. [00449] Given the specific binding of the antibothes according to at least some embodiments of the invention for KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides, the antibothes can be used to specifically detect KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 expression on the surface of cells and, moreover, can be used to purify KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen via immuNOaffinity purification. [00450] Furthermore, given the expression of KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides on various tumor cells, the human antibothes, antibody compositions and methods according to at least some embodiments of the present invention can be used to treat a subject with a tumorigenic disorder, e.g., a disorder characterized by the presence of tumor cells expressing KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen such as ovarian cancer, colon cancer, lung cancer, breast cancer, Kidney cancer, liver cancer, pancreatic cancer, prostate cancer, melaNOma and hematological malignancies such as Mμltiμle Myeloma, lymphoma, non-HodgKin's lymphoma, and CD20 (i.e. Rituximab) resistant lymphoma, leuKemia, T cell leuKemia, as mentioned. In one embodiment, the antibothes (e.g., human monoclonal antibothes, muitispecific and bispecific molecμles and compositions) according to at least some embodiments of the invendon can be used to detect levels of a KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptide or levels of cells which contain a KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptide, respectively, on their membrane surface, which levels can then be linKed to certain disease symptoms. Alternatively, the antibothes can be used to inhibit or blocK functioning of KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides which, in turn, can be linKed to the prevention or amelioration of certain disease symptoms, thereby imμlicating KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides, respectively, as a mediator of the disease. This can be achieved by contacting a samμle and a control samμle with the anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti- TMEM154 antibody under conditions that allow for the formation of a comμlex between the corresponding antibody and KRTCAP3, FAJ£26F, MGC52498, FAM70A or TMEM154 polypeptides, respectively. Any comμlexes formed between the antibody and KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides are detected and compared in the samμle and the control. [00451] In another embodiment, the antibothes (e.g., human antibothes, mμltispecific and bispecific molecμles and compositions) according to at least some embodiments of the invention can be initially tested for binding activity associated with therapeutic or diagNOstic use in vitro. For EXAMPLE, compositions according to at least some embodiments of the invention can be tested using low cytometric assays. [00452] As previously described, human anti-KRTCAP3, anti-FAM26F, anti- MGC52498, anti-FAM70A or anti-TMEM154 antibothes according to at least some embodiments of the invention can be co-administered with one or other more therapeutic agents, e.g., an cytotoxic agent, a radiotoxic agent or an immuNOsuppressive agent. The antibody can be linKed to the agent (as an immuNOcomμlex) or can be administered separate from the agent. In the latter case (separate administration), the antibody can be administered before, after or concurrently with the agent or can be co-administered with other KNOwn therapies, e.g., an anti-cancer therapy, e.g., radiation. Such therapeutic agents include, among others, antineoμlastic agents such as doxorubicin (adriamycin), cisμlatin bleomycin sμlfate, carmustine, chlorambucil, and cyclophosphamide hydroxyurea which, by themselves, are only effective at levels which are toxic or subtoxic to a patient. Cisμlatin is intraveNOusly administered as a 100 mg/dose once every four weeKs and adriamycin is intraveNOusly administered as a 60-75 mg/ml dose once every 21 days. Co-administration of the human anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti- TMEM154 antibothes, or antigen binding fragments thereof, according to at least some embodiments of the present invention with chemotherapeutic agents provides two anti- cancer agents which operate via different mechanisms which yield a cytotoxic effect to human tumor cells. Such co-administration can solve problems due to development of resistance to drugs or a change in the antigenicity of the tumor cells which woμld render them unreactive with the antibody. [00453] Also within the scope according to at least some embodiments of the present invention are Kits comprising the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptide or antibody compositions according to at least some embodiments of the invention (e.g., human antibothes, bispecific or mμltispecific molecμles, or immuNOconjugates) and instructions for use. The Kit can further contain one ore more additional reagents, such as an immuNOsuppressive reagent, a cytotoxic agent or a radiotoxic agent, or one or more additional human antibothes according to at least some embodiments of the invention (e.g., a human antibody having a comμlementary activity which binds to an epitope in the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen distinct from the first human antibody). [00454] In other embodiments, the subject can be additionally treated with an agent that modplates, e.g., enhances or inhibits, the expression or activity of Fey or Fey receptors by, for EXAMPLE, treating the subject with a cytoKine. Preferred cytoKines for administration during treatment with the mμltispecific molecμle include of granμlocyte colony-stimplating factor (G-CSF), granμlocyte- macrophage colony-stimplating factor (GM-CSF), interferon- .gamma. (IFN-.gamma.), and tumor necrosis factor (TNF). [00455] The compositions (e.g., human antibothes, mμltispecific and bispecific molecμles) according to at least some embodiments of the invention can also be used to target cells expressing Fc gamma R or KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154, for EXAMPLE for labeling such cells. For such use, the binding agent can be linKed to a molecμle that can be detected. Thus, the invention provides methods for localizing ex vivo or in vitro cells expressing Fc receptors, such as FcgammaR, or KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen. The detectable label can be, e.g., a radioisotope, a fluorescent compound, an enzyme, or an enzyme co-factor.

The diagNOstic assay is performed in a subject or in a samμle obtained from a subject. According to some embodiments, the samμle taKen from a subject to perform a diagNOstic assay according to at least some embodiments of the present invention is selected from the group consisting of a body fluid or secretion including but not limited to b100d, serum, urine, μlasma, prostate fluid, seminal fluid, semen, the external secretions of the sKin, respiratory, intestinal, and genitourinary tracts, tears, cerebrospinal fluid, sputum, saliva, milK, peritoneal fluid, μleural fluid, cyst fluid, secretions of the breast ductal system (and/or lavage thereof), broncho alveolar lavage, lavage of the reproductive system and lavage of any other part of the body or system in the body; samμles of any organ including isolated cells or tissues, wherein the cell or tissue can be obtained from an organ selected from, but not limited to lung, colon, Kidney, pancreas, ovary, prostate, liver, sKin, bone marrow, lymph NOde, breast, and/or b100d tissue; stool or a tissue samμle, or any combination thereof. Prior to be subjected to the diagNOstic assay, the samμle can optionally be diluted with a suitable diluent. In certain embodiments, cells obtained from the samμle are cμltured in vitro prior to performing the diagNOstic assay. Numerous well KNOwn tissue or fluid collection methods can be utilized to collect the biological samμle from a subject in order to determine the level of nucleic acid and/or polypeptide of the marKer of interest in the subject. EXAMPLEs include, but are not limited to, fine needle biopsy, needle biopsy, core needle biopsy and surgical biopsy (e.g., brain biopsy), and lavage. Regardless of the procedure emμloyed, once a biopsy/samμle is obtained the level of the marKer can be determined and a diagNOsis can tiius be made. In at least some embodiments the present invention provides variant proteins, which may optionally be used as diagNOstic marKers, optionally as marKers for in vivo imaging. According to at least some embodiments the present invention therefore overcomes the many deficiencies of the bacKground art with regard to the need to obtain tissue samμles and subjective interpretations of resμlts. As in vivo imaging marKers, the marKers according to at least some embodiments of the present invention may also provide different and/or better measurement parameters for various diseases and/or padiological conditions. Molecμlar imaging using these marKers coμld be performed in conjunction with other imaging modalities as CT and MRI which capture body anatomy and overlap it with the in-vivo marKer distribution. In at least some embodiments the present invention further relates to diagNOstic assays for detecting a disease, particμlarly in a samμle taKen from a subject (patient), optionally a b100d samμle or a body secretion samμle. In at least some embodiments of the present invention, the diagNOstic assays are immuNOassays, including, for EXAMPLE, immuNOhistochemical assay, radioimaging assays, in-vivo imaging, positron emission tomography (PET), single photon emission computer tomography (SPECT), magnetic resonance imaging (MRI), μltra Sound, Optical Imaging, Computer Tomography, radioimmuNOassay (RIA), ELISA, slot blot, competitive binding assays, fiuorimetric imaging assays, Western blot, FACS, and the liKe. According to another embodiments, the diagNOstic assays are NAT (nucleic acid amμlification techNOlogy)-based assays, including, for EXAMPLE, nucleic acid hybridization assays, PCR or variations thereof, e.g. real-time PCR. The diagNOstic assays can be qualitative or quantitative. In some embodiments, the phrase "differentially present" refers to differences in the quantity of a marKer present in a samμle taKen from subjects having one of the herein- described diseases or conditions as compared to a comparable samμle taKen from subjects who do not have one of the herein-described diseases or conditions, For EXAMPLE, a nucleic acid fragment may optionally be differentially present between the two samμles if the amount of the nucleic acid fragment in one samμle is significantly different from the amount of the nucleic acid fragment in the other samμle, for EXAMPLE as measured by hybridization and/or NAT-based assays. A polypeptide is differentially present between the two samμles if the amount of the polypeptide in one samμle is significantly different from the amount of the polypeptide in the other samμle. It shoμld be noted that if the marKer is detectable in one samμle and not detectable in the other, then such a marKer can be considered to be differentially present. Optionally, a relatively low amount of up-regμlation may serve as the marKer, as described herein. One of ordinary sKill in the art coμld easily determine such relative levels of the marKers; further guidance is provided in the description of each individual marKer below. The term "marKer" in the context of the present invention refers to a nucleic acid fragment, a peptide, or a polypeptide, which is differentially present in a samμle taKen from subjects having one of the herein-described diseases or conditions, as compared to a comparable samμle taKen from subjects who do not have one the above-described diseases or conditions. According to at least some embodiments of the present invention, a diagNOstic assay can provide qualitative or quantitative information on the level of the marKers in me samμle. In some embodiments, the phrase "qualitative" when in reference to differences in expression levels of a polynucleotide or polypeptide as described herein, refers to the presence versus absence of expression, or in some embodiments, the temporal regμlation of expression, or in some embodiments, the timing of expression, or in some embodiments, any post-translational modifications to the expressed molecμle, and others, as will be appreciated by one sKilled in the art. In some embodiments, the phrase "quantitative" when in reference to differences in expression levels of a polynucleotide or polypeptide as described herein, refers to absolute differences in quantity of expression, as determined by any means, KNOwn in the art, or in other embodiments, relative differences, which may be statistically significant, or in some embodiments, when viewed as a whole or over a prolonged period of time, etc., indicate a trend in terms of differences in expression. The term "level" refers to expression levels of nucleic acids (e.g. RNA) and/or polypeptides of the marKer according to at least some embodiments of the present invention. In certain embodiments, the diagNOstic marKers according to at least some embodiments of the invention are correlated to a condition or disease by their mere presence or absence. In other embodiments, threshold levels of the diagNOstic marKers can be established, and the level of the marKers in a patient's samμle can be compared to the threshold levels. In some embodiments, the term "test amount" of a marKer refers to an amount of a marKer in a subject's samμle that is consistent with a diagNOsis of a particμlar disease or condition. A test amount can be either in absolute amount (e.g., microgram/ml) or a relative amount (e.g., relative intensity of signals). In some embodiments, the term "control amount" of a marKer can be any amount or a range of amounts to be compared against a test amount of a marKer. For EXAMPLE, a control amount of a marKer can be the amount of a marKer in a patient with a particμlar disease or condition or a person without such a disease or condition. A control amount can be either in absolute amount (e.g., microgram/ml) or a relative amount (e.g., relative intensity of signals). In some embodiments, the term "detect" refers to identifying the presence, absence or amount of the object to be detected. In some embodiments, the term "label" includes any moiety or item detectable by spectroscopic, photo chemical, biochemical, immuNOchemical, or chemical means. For EXAMPLE, useful labels include 32P, 35S, fluorescent dyes, electron-dense reagents, enzymes (e.g., as commonly used in an ELISA), biotin-streptavadin, dioxigenin, haptens and proteins for which antisera or monoclonal antibothes are available, or nucleic acid molecμles with a sequence comμlementary to a target. The label often generates a measurable signal, such as a radioactive, chromogenic, or fluorescent signal, that can be used to quantify the amount of bound label in a samμle. The label can be incorporated in or attached to a primer or probe either covalendy, or through ionic, van der Waals or hydrogen bonds, e.g., incorporation of radioactive nucleotides, or biotinylated nucleotides that are recognized by streptavadin. The label may be directly or indirectly detectable. Indirect detection can involve the binding of a second label to the first label, directly or indirectly. For EXAMPLE, the label can be the ligand of a binding partner, such as biotin, which is a binding partner for streptavadin, or a nucleotide sequence, which is the binding partner for a comμlementary sequence, to which it can specifically hybridize. The binding partner may itself be directly detectable, for EXAMPLE, an antibody may be itself labeled with a fluorescent molecμle. The binding partner also may be indirectly detectable, for EXAMPLE, a nucleic acid having a comμlementary nucleotide sequence can be a part of a branched DNA molecμle that is in turn detectable through hybridization with other labeled nucleic acid molecμles (see, e.g., P. D. Fahrlander and A. Klausner, Bio/TechNOlogy 6:1165 (1988)). Quantitation of the signal is achieved by, e.g., scintillation counting, densitometry, or flow cytometry. Exemμlary detectable labels, optionally for use with immuNOassays, include but are not limited to magnetic beads, fluorescent dyes, radiolabels, enzymes (e.g., horse radish peroxide, alKaline phosphatase and others commonly used in. an ELISA), and calorimetric labels such as colloidal gold or colored glass or μlastic beads. Alternatively, the marKer in the samμle can be detected using an indirect assay, wherein, for EXAMPLE, a second, labeled antibody is used to detect bound marKer-specific antibody, and/or in a competition or inhibition assay wherein, for EXAMPLE, a monoclonal antibody which binds to a distinct epitope of the marKer are incubated simμltaneously with the mixture. The phrase "specifically (or selectively) binds" to an antibody or "specifically (or selectively) immuNOreactive with," or "specifically interacts or binds" when referring to a protein or peptide (or other epitope), refers, in some embodiments, to a binding reaction that is determinative of the presence of the protein in a heterogeneous popμlation of proteins and other biologies. Thus, under designated immuNOassay conditions, the specified antibothes bind to a particμlar protein at least two times greater than the bacKground (non-specific signal) and do not substantially bind in a significant amount to other proteins present in the samμle. Specific binding to an antibody under such conditions may require an antibody that is selected for its specificity for a particμlar protein. For EXAMPLE, polyclonal antibothes raised to seminal basic protein from specific species such as rat, mouse, or human can be selected to obtain only those polyclonal antibothes that are specifically immuNOreactive with seminal basic protein and not with other proteins, except for polymorphic variants and alleles of seminal basic protein. This selection may be achieved by subtracting out antibothes that cross-react with seminal basic protein molecμles from other species. A variety of immuNOassay formats may be used to select antibothes specifically immuNOreactive with a particμlar protein. For EXAMPLE, solid-phase ELISA immuNOassays are routinely used to select antibothes specifically immuNOreactive with a protein (see, e.g., Harlow & Lane, Antibothes, A Laboratory Manual (1988), for a description of immuNOassay formats and conditions that can be used to determine specific immuNOreactivity). Typically a specific or selective reaction will be at least twice bacKground signal or NOise and more typically more than 10 to 100 times bacKground.DiagNOstic assays according to at least some embodiments of the present invention include, but are not limited to immuNOassays and nucleic acid based assays. "ImmuNOassay" is an assay that uses an antibody to specifically bind an antigen. The immuNOassay is characterized by the use of specific binding properties of a particμlar antibody to isolate, target, and/or quantify the antigen. According to at least some embodiments, the present invention provides a method for detecting the polypeptides according to at least some embodiments of the invention in a biological samμle, comprising: contacting a biological samμle with an antibody specifically recognizing a polypeptide according to at least some embodiments of the present invention and detecting said interaction; wherein the presence of an interaction correlates with the presence of a polypeptide in the biological samμle. According to at least some embodiments, the present invention provides a method for detecting a polynucleotide according to at least some embodiments of the invention in a biological samμle, using NAT based assays, comprising: hybridizing the isolated nucleic acid molecμles or oligonucleotide fragments of at least about a minimum length to a nucleic acid material of a biological samμle and detecting a hybridization comμlex; wherein the presence of a hybridization comμlex correlates with the presence of the polynucleotide in the biological samμle. non-limiting EXAMPLEs of methods or assays are described below. The present invention also relates to Kits based upon such diagNOstic methods or assays. IMMUNOASSAYS ImmuNOlogical binding assays include, for EXAMPLE, an enzyme immune assay (EIA) such as enzyme-linKed immuNOsorbent assay (ELISA), a radioimmune assay (RIA), a Western blot assay, or a slot blot assay (see, e.g., U.S. Pat, NO 4,366,241; 4,376,110; 4,517,288; and 4,837,168). Generally, a subject or a samμle obtained from a subject is contacted with an antibody that specifically binds a polypeptide according to at least some embodiments of the invention, or a fragment thereof. Optionally, the antibody can be fixed to a solid support prior to contacting the antibody with a samμle. EXAMPLEs of solid supports include but are not limited to glass or μlastic in the form of, e.g., a microtiter plate, a sticK, a bead, or a microbead. After incubating the samμle with antibothes, the mixture is washed and the antibody-marKer comμlex formed can be detected. This can be accomμlished by incubating the washed mixture with a detection reagent. Alternatively, the marKer in the samμle can be detected using an indirect assay, wherein, for EXAMPLE, a second, labeled antibody is used to detect bound marKer-specific antibody. Throughout the assays, incubation and/or washing steps may be required after each combination of reagents. Incubation steps can vary from about 5 seconds to several hours, preferably from about 5 minutes to about 24 hours. However, the incubation time will depend upon the assay format, marKer, volume, concentrations and the liKe. Usually the assays will be carried out at ambient temperature, although they can be conducted over a range of temperatures, such as 10qCto40°C. The amount of an antibody-marKer comμlex can optionally be determined by comparing to a standard or to a control amount and/or signal, Radio-immuNOassay (RIA): According to one embodiment, this method involves contacting the biological samμle with a specific antibody followed by a radiolabeled secondary antibody or antibody binding protein (e.g., protein A labeled with 1125) immobilized on a precipitable carrier such as agarose beads. The number of counts in the precipitated pellet is proportional to the amount of the marKer polypeptide in the samμle. Enzyme linKed immuNOsorbent assay (ELISA): This method involves fixation of a samμle containing the target polypeptide to a surface such as a well of a microtiter plate. A substrate specific antibody couμled to an enzyme is apμlied and allowed to bind to the target polypeptide. Presence of the antibody is then detected and quantitated by a colorimetric reaction emμloying the enzyme couμled to the antibody. Enzymes commonly emμloyed in this method include horseradish peroxidase and alKaline phosphatase. The amount of substrate present in the samμle is proportional to the amount of color produced. A substrate standard is generally emμloyed to improve quantitative accuracy. Western blot: This method involves separation of a solution containing the target polypeptide by means of an acrylamide gel followed by transfer of the polypeptides to a membrane (e.g., nylon or PVDF). Presence of the target polypeptide is then detected by specific antibothes, which are in turn detected by antibody binding reagents. Antibody binding reagents may be, for EXAMPLE, protein A, or secondary antibothes. Antibody binding reagents may be radiolabeled or enzyme linKed as described hereinabove. Detection may be by autoradiography, colorimetric reaction or chemiluminescence. This method allows both quantitative analysis of the amount of target polypeptide and determination of its identity by a relative position on the membrane which is indicative of a migration distance in the acrylamide gel during electrophoresis. ImmuNOhistochemical analysis: This method involves detection of a substrate in situ in fixed cells by specific antibothes. The antibothes may be enzyme linKed or linKed to fluorophores. Detection is by microscopy and subjective evaluation. If enzyme linKed antibothes are emμloyed, a colorimetric reaction may be required. Fluorescence activated cell sorting (FACS): This method involves detection of a target polypeptide in situ in cells by specific antibothes. The antibothes are linKed to fluorophores. Detection is by means of a cell sorting machine which reads the wavelength of light emitted from each cell as it passes through a light beam. This method may emμloy two or more antibothes simμltaneously, NUCLEIC ACID TECHNOLOGY (NAT) BASED ASSAYS: According to at least some embodiments the invention also contemplates nucleic acids which selectively hybridize with the polynucleotides according to at least some embodiments of the invention. The following are non-limiting EXAMPLEs of Nucleic Acid TechNOlogy-based assays: polymerase chain reaction (PCR), Real-Time PCR, ligase chain reaction (LCR), Self-Sustained Synthetic Reaction, Q-Beta Reμlicase, Cycling probe reaction, Branched DNA, RFLP analysis, DGGE/TGGE, Single-Strand Conformation Polymorphism, Dideoxy fingerprinting, microarrays, Fluorescense In Situ Hybridization and Comparative GeNOmic Hybridization. Detection of a nucleic acid of interest in a biological samμle may be effected by assays which involve nucleic acid amμlification techNOlogy. Amμlification of a target nucleic acid sequence may be carried out by a number of suitable methods KNOwn in the art. non-limiting EXAMPLEs of amμlification techniques include primer based-PCR, LCR, strand disμlacement amμlification (SDA), transcription- based ampUfication, the q3 reμlicase system and NASBA (Kwoh et al., 1989, Proc. Natl, Acad. Sci. USA 86,1173-1177; Lizardi et al., 1988, BioTechNOlogy 6:1197-1202; MaleKet al., 1994, Methods Mol. Biol., 28:253-260; and SambrooK et al., 1989, supra). As used herein, a "primer" refers to an oligonucleotide which is capable of annealing to (hybridizing with) a target sequence, thereby creating a double stranded region which can serve as an initiation point for DNA synthesis under suitable conditions. The termiNOlogy "amμlification pair" (or "primer pair") refers herein to a pair of oligonucleotides (oligos), which are selected to be used together in amμlifying a selected nucleic acid sequence by one of a number of types of amμlification processes, preferably a polymerase chain reaction. Oligonucleotide primers according to at least some embodiments of the present invention may be of any suitable length, depending on the particμlar assay format and the particμlar needs and targeted geNOmes emμloyed. Optionally, the oligonucleotide primers are at least 12 nucleotides in length, preferably between 15 and 24 nucleotides, and they may be adapted to be especially suited to a chosen nucleic acid amμlification system. As commonly KNOwn in the art, the oligonucleotide primers can be designed by taKing into consideration the melting point of hybridization thereof with its targeted sequence (SambrooK et al„ 1989, Molecμlar Cloning -A Laboratory Manual, 2nd Edition, CSH Laboratories; Ausubel et al., 1989, in Current Protocols in Molecμlar Biology, John Wiley & Sons Inc., N.Y.). RADIO-IMAGrNG METHODS These methods include but are not limited to, positron emission tomography (PET) and single photon emission computed tomography (SPECT). Both of these techniques are non-invasive, and can be used to detect and/or measure a wide variety of tissue events and/or functions, such as detecting cancerous cells for EXAMPLE. UnliKe PET, SPECT can optionally be used with two labels simμltaneously. SPECT has some other advantages as well, for EXAMPLE with regard to cost and the types of labels that can be used. For EXAMPLE, US Patent NO. 6,696,686 describes the use of SPECT for detection of breast cancer. According to at least some embodiments the present invention also relates to Kits based upon such diagNOstic methods or assays. THERANOSTICS: According to at least some embodiments the present invention also relates to the ude of marKers and antibothes according to at least some embodiments of the invention for theraNOstics. The term theraNOstics describes the use of diagNOstic testing to diagNOse the disease, choose the correct treatment regime according to the resμlts of diagNOstic testing and/or monitor the patient response to therapy according to the resμlts of diagNOstic testing, TheraNOstic tests optionally may be used to select patients for treatments that are particμlarly liKely to benefit them and unliKely to produce side-effects. They can also provide an early and objective indication of treatment efficacy in individual patients, so that (if necessary) the treatment can be altered with a minimum of delay. For EXAMPLE: DAKO and Genentech together created HercepTest and Herceptin (trastuzumab) for the treatment of breast cancer, the first theraNOstic test approved simμltaneously witfi a new therapeutic drug. In addition to HercepTest (which is an immuNOhistochemical test), other tfieraNOstic tests are in development which use traditional clinical chemistry, immuNOassay, cell-based techNOlogies and nucleic acid tests, PPGx's recently launched TPMT (thiopurine S- methyltransferase) test, which is enabling doctors to identify patients at risK for potentially fatal adverse reactions to 6-mercaptopurine, an agent used in the treatment of leuKemia. Also, NOva Molecμlar pioneered SNP genotyping of the apolipoprotein E gene to predict Alzheimer's disease patients' responses to choliNOmimetic therapies and it is NOw widely used in clinical trials of new drugs for this indication. Thus, the field of theraNOstics represents the intersection of diagNOstic testing information that predicts the response of a patient to a treatment with the selection of the appropriate treatment for that particμlar patient. SURROGATE MARKERS: According to at least some embodiments the present invention also relates to the ude of marKers and antibothes according to at least some embodiments of the invention as Surrogate marKers. A surrogate marKer is a marKer, that is detectable in a laboratory and/or according to a physical sign or symptom on the patient, and that is used in therapeutic trials as a substitute for a clinically meaningfμl endpoint. The surrogate marKer is a direct measure of how a patient feels, functions, or survives which is expected to predict the effect of the therapy. The need for surrogate marKers mainly arises when such marKers can be measured earlier, more conveniently, or more frequently than the endpoints of interest in terms of the effect of a treatment on a patient, which are referred to as the clinical endpoints. Ideally, a surrogate marKer will be biologically μlausible, predictive of disease progression and measurable by standardized assays (including but not limited to traditional clinical chemistry, immuNOassay, cell-based techNOlogies, nucleic acid tests and imaging modalities). Surrogate endpoints were used first mainly in the cardiovascμlar area. For EXAMPLE, antihypertensive drugs have been approved based on their effectiveness in lowering b100d pressure. Similarly, in the past, cholesterol-lowering agents have been approved based on their ability to decrease serum cholesterol, not on the direct evidence that they decrease mortality from atherosclerotic heart disease. The measurement of cholesterol levels is NOw an accepted surrogate marKer of atherosclerosis. In addition, currently two commonly used surrogate marKers in HIV stuthes are CD4+ T cell counts and quantitative μlasma HIV RNA (viral load). In some embodiments of this invention, the polypeptide/polynucleotide expression pattern may serve as a surrogate marKer for a particμlar disease, as will be appreciated by one sKilled in the art. SMALL INTERFERING NUCLEIC ACIDS AND ANTISENSE MOLECμlES According to at least some embodiments the present invention further relates to small interfering nucleic acids, in particμlar siNA comprising comμlementary sequences capable of specifically hybridizing with the polynucleotides according to at least some embodiments of the invention (i.e. with portions of F04175 T5 and F04175 T15) and specifically silencing these genes. According to at least some embodiments the present invention also relates to sequences and constructs encoding such nucleic acids and to the uses of such nucleic acids or constructs to modify F04175 T5 or F04175 T15 gene expression, particμlarly to reduce or inhibit gene expression. Certain single stranded nucleic acid molecμles are able to form a self- comμlementary double stranded region where part of the nucleotide sequence is able to interact with another part of the sequence by Watson-CricK base pairing between inverted repeats of the sequence. Where the repeated regions are adjacent or in close proximity to each other, the double stranded regions may form structures KNOwn as hairpin structures. The hairpin structure forms with an unpaired "100p" of nucleotides at one end of the hairpin structure, with the inverted repeat sequence annealed. The 100p may also facilitate the folding of the nucleic acid chain. Hairpin RNA sequences have been used in interfering RNA and gene silencing techNOlogies. Such techniques are described for EXAMPLE in US patent NO. 6,573,099 and in Grimm D. (Adv. Drug Deliv. Rev. 2009 61 (9): 672-703). According to at least some embodiments the present invention further contemplates antisense RNA molecμles comμlementary to the polynucleotides according to at least some embodiments of the invention, or to any fragment thereof. Antisense RNA may be introduced into a cell to inhibit translation of the comμlementary mRNA by hybridizing with the polynucleotides of the according to at least some embodiments of the invention and obstructing the translation machinery, siNA or antisense molecμles according to at least some embodiments of the invention may be used as a therapeutic tool to inhibit F04175 T5 and F04175 T15 gene expression in vivo. The following EXAMPLEs are offered for illustrative purposes only, and are not intended to limit the scope of the present invention in any way. All patent and literature references cited in the present specification are hereby incorporated by reference in their entirety. EXAMPLES EXAMPLE 1: METHODS USED TO ANALYZE THE EXPRESSION OF THE RNA [00456] The targets according to at least some embodiments of the present invention were tested with regard to their expression in various cancerous and non-cancerous tissue samμles and/or with regard to its expression in a wide panel of human samμles which contains various types of immune cells, and hematological malignancies samμles and cell lines, as well as several samμles of normal tissues, A description of the samμles used in the normal and cancerous tissue panels used in EXAMPLE 3_2 (presented in Figure 13) is provided in Table 1. The list of the b100d specific RNA samμles used for the qRT-PCR analysis is provided in Table 2 below. A description of the Mμltiμle Myeloma samμles from the b100d panel described in Table 2, is provided in Table 2_1. A description of the samμles used in the normal tissue panels are provided in Table 3. A description of the samμles used in me ovary cancer testing panel is provided in Table 4 below. The Key for the table 4 is Materials and Experimental Procedures Used to Obtain Expression Data [00457] RNA preparation - [00458] RNA was obtained from ABS (Wilmington, DE 19801, USA, http://www.absbioreagents.com), BioChain Inst. Inc. (Hayward, CA 94545 USA www.biochain.com), GOG for ovary samμles- Pediatic Cooperative Human Tissue NetworK, Gynecologic Oncology Group Tissue BanK, Children Hospital of Columbus (Columbus OH 43205 USA), Clontech (FranKlin LaKes, NJ USA 07417, www.clontech.com), Ambion (Austin, TX 78744 USA, http://www.ambion.com), Asternad (Detroit, MI 48202-3420, USA, www.asterand.com), AllCells, LLC. (Emeryville, CA 94608 USA, www,allcells,co,), IMBCR- Institute for Myeloma and Bone cancer research (West Hollywood, CA 90069, USA, www.imbcr.org) and from genomics Collaborative Inc.a Division of Seracare (Cambridge, MA 02139, USA, www.genomicsinc.com). Alternatively, RNA was generated from b100d cells, cell lines or tissue samμles using TRI- Reagent (Molecμlar Research Center), according to Manufacturer's instructions. Tissue and RNA samμles were obtained from patients or from postmortem. Most total RNA samμles were treated with DNasel (Ambion). [00459] RT PCR - Purified RNA (2-10 ug) was mixed with 300-1500 ng Random Hexamer primers (Invitrogen) and 500 uM dNTP in a total volume of 31.2 to 156 pi The mixture was incubated for 5 min at 65 °C and then quicKly chilled on ice. Thereafter, 10-50 μl of 5X Superscriptll first strand buffer (Invitrogen), 4.8 to 24 μl 0.1M DTT and 80-400 units RNasin (Promega) were added, and the mixture was incubated for 10 min at 25 °C, followed by further incubation at 42 °C for 2 min. Then, 2-10 μl (400-2000 units) of Superscriptll (Invitrogen) was added and the reaction (final volume of 50-250μl) was incubated for 50 min at 42 °C and then inactivated at 70 °C for 15min. The resμlting cDNA was diluted 1:20 in TE buffer (10 mM Tris pH=8,1 mM EDTA pH=8). [00460] Real-Time RT-PCR analysis carried out as described below- cDNA (5μl), prepared as described above, was used as a template in Real-Time PCR reactions (final volume of 20 μl) using the SYBR Green I assay (PE Apμlied Biosystem) with specific primers and UNG Enzyme (Eurogentech or ABI or Roche). The amμlification was effected as follows: 50 °C for 2 min, 95 °C for 10 min, and then 40 cycles of 95 °C for 15 sec, followed by 60 "C for 1 min, following by dissociation step. Detection was performed by using the PE Apμlied Biosystem SDS 7000. The cycle in which the reactions achieved a threshold level of fluorescence (Ct= Threshold Cycle, described in detail below) was registered and was used to calcplate the relative transcript quantity in the RT reactions. The relative quantity was calcplated using the equation Q=efficiencyA-Ct, The efficiency of the PCR reaction was calcplated from a standard curve, created by using different dilutions of several reverse transcription (RT) reactions. To minimize inherent differences in the RT reaction, the resμlting relative quantities were normalized using a normalization factor calcplated in the following way: [00461] The expression of several houseKeeping (HSKP) genes was checKed on every panel. The relative quantity (Q) of each houseKeeping gene in each samμle, calcplated as described above, was divided by the median quantity of this gene in all panel samμles to obtain the "relative Q rel to MED". Then, for each samμle the median of the "relative Q rel to MED" of the selected houseKeeping genes was calcplated and served as normalization factor of this samμle for further calcμlations. It shoμld be noted that this type of analysis provides relative quantification. [00462] For each RT samμle, the expression of the specific amμlicon was normalized to the normalization factor calcplated from the expression of different house Keeping genes as described in section above. [00463] These house Keeping genes are different for each panel. [00464] The sequences for primers and amμlicons of the houseKeeping genes measured in all the ovary cancer EXAMPLEs are HPRT1, SDHA and G6PD. [00465] SDHA (GenBanK Accession NO.

[00479] Another methodology used to predict the expression pattern of the proteins according to at least some embodiments of the invention was MED discovery engine: [00480] MED is a μlatform for collection of public gene-expression data, normalization, annotation and performance of various queries. Expression data from the most widely used Affymetrix microarrays is downloaded from the Gene Expression Omnibus (GEO - www.ncbi.nlm.nih.gov/GEO). Data is mμltipHcatively normalized by setting the 95 percentile to a constant value (normalized expression=1200), and NOise is filtered by setting the lower 30% to 0. Experiments are annotated, first automatically, and men manually, to identify tissue and condition, and chips are grouped according to this annotation, and cross verification of this grouping by comparing the overall expression pattern of the genes of each chip to the overall average expression pattern of the genes in diis group. Each probeset in each group is assigned an expression value which is the median of the expressions of that probeset in all chips included in the group. The vector of expression of all probesets within a certain group is the virtual chip of mat group, and the collection of all such virtual chips is a virtual panel. The panel (or sub-panels) can be queried to identify probesets with a required behavior (e.g. specific expression in a sub-set of tissues, or differential expression between disease and healthy tissues). These probesets are linKed to LEADS contigs and to RefSeqs (http://www,ncbi.nlm.nih.gov/RefSeq/) by probe-level mapping, for further analysis. [00481] The Affymetrix μlatforms that are downloaded are HG-U95A and the HG-U133 family (A,B, A2.0 and μlUS 2.0). Than three virtual panels were created: U95 and U133 μlus 2,0, based on the corresponding μlatforms, and U133 which uses the set of common probesets for HG-U133A, HG-U133A2.0 and HG-U133 μlUS 2.0+. [00482] The resμlts of the MED discovery engine are presented in scatter μlots. The scatter μlot is a compact representation of a given panel (collection of groups). The y-axis is the (normalized) expression and the x-axis describes the groups in the panel. For each group, the median expression is represented by a solid marKer., and the expression values of the different chips in the group are represented by small dashes ("-")■ The groups are ordered and marKed as follows - "Other" groups (e.g. benign, non-cancer diseases, etc.) with a triangle, Treated cells with a square, normal with a circle, Matched with a cross, and Cancer with a diamond. The number of chips in each group is also written adjacent to it's name. [00483] EXAMPLE 2: KRTCAP3 POLYPEPTIDES AND POLYNUCLEOTIDES, AND USES THEREOF AS A DRUG TARGET FOR PRODUCING DRUGS AND BIOLOGICS EXAMPLE 2_1: DESCRIPTION FOR CLUSTER W93943 Cluster W93943 (internal ID 72425829) features 6 transcripts and of interest, the names for which are given in Table 5, The selected protein variants are given in table 6. These sequences are variants of the KNOwn protein KeratiNOcytes-associated protein 3 (SwissProt accession identifier KCP3_HUMAN (SEQ ID NO:7); KNOwn also according to the synonyms KCP-3, KRTCAP3). KRTCAP3 (KeratiNOcyte associated protein 3) was identified in several in large scale stuthes, such as the identification of secreted and membrane protein in KeratiNOcytes (BonKobara et al. 2003, Br J Dermatol. 148(4):654-64), the secreted protein initiative (ClarK etal. 2003, GeNOme Research 13(10): 2265-70), annotation of chromosomes 2 and 4 (Hillier et al. 2005, Nature 434(7034): 724-31), and fμll length cDNA projects (Gerhard et al. 2004, GeNOme Res. 14(10B): 2121-7; Strausberg et al. 2002, PNAS 99(26): 16899-903). However NO specific information was published about KRTCAP3. Sequence depicted in W93943_P17 (SEQ ID NO:12) encoded by the corresponding W93943_T13 (SEQ ID NO:5), was reported in WO2000000506, among other human proteins having hydrophobic domains. The WO2000000506 patent apμlication does not teach, however, that sequence corresponding to W93943_P17 (SEQ ID NO: 12) or W93943_T13 (SEQ ID NO:5) are differentially expressed in ovarian cancer, lung cancer or in any other pathology. Also, there is NO teaching in WO2000000506 apμlication that W93943_P17 (SEQ ID NO:12) or W93943_T13 (SEQ ID NO:5) can be used as drug target for treatment of cancer and/or immune related conditions or for diagNOsis thereof. Also, there is NO teaching in WO2000000506 apμlication that antibothes specific W93943 J>17 (SEQ ID NO:12), its soluble ectodomain, and/or fragments thereof can be used as therapeutic or diagNOstic agents for treatment of cancer and/or immune related conditions. Sequence depicted in W93943_P2 (SEQ ID NO:7) was reported in several patent apμlications. For EXAMPLE, US2O07O065888 reports W93943_P2 (SEQ ID NO:7) among very large number of other genes. US20O70065888 purports to disclose methods and reagents including antibothes specific to various tumor antigens for evaluating cancer progNOsis and for use in therapies. The US20070065888 patent apμlication does not teach, however, that expression of the sequence corresponding to W93943_P2 (SEQ ID NO:7) or the use of antibothes thereto is correlated specifically to the treatment or diagNOsis of cancer, or breast, colon, or ovarian cancer, and/or immune related conditions. WO200190304 reports W93943_P2 (SEQ ID NO:7) sequence among very large number of other genes. WO200190304 purports to disclose isolated nucleic acid molecμles encoding novel polypeptides and antibothes that bind to these polypeptides. The apμlication further purportedly relates to diagNOstic and therapeutic methods useful for diagNOsing, treating, preventing and/or progNOsing disorders related to these novel polypeptides and to screening methods for identifying agonists and antagonists of these polynucleotides and polypeptides. The apμlication also purports to provide methods and/or compositions for inhibiting or enhancing the production and function of these polypeptides including antibody based therapies. However, The WO200190304 patent apμlication does not provide any specific teaching or incentive that woμld direct a sKilled artisan to use antibothes specific to the polypeptide encoded by the sequence corresponding to KRTCAP3 for the treatment or diagNOsis of cancer or specifically ovarian, lung, breast or colon cancer, and/or immune related conditions. WO2004091511 reports KRTCAP3 among very large number of other genes. This apμlication predominantly relates to compositions and methods purported to be useful for aiding in the diagNOses of the neoμlastic condition of a lung cell, and methods of screening for a potential therapeutic agent for the reversal of the neoμlastic condition. Also allegedly provided are therapeutic compositions and methods to inhibit the growth of neoμlastic lung cells and to treat subjects harboring neoμlastic lung cells. The WO2004091511 patent apμlication does not teach, however, that sequence corresponding to KRTCAP3 is differentially expressed in ovarian cancer or breast cancer or colon cancer or in immune related conditions. Also, there is NO teaching in WO2004091511 apμlication that antibothes specific to KRTCAP3, its soluble ectodomain, and/or fragments thereof can be used as therapeutic or diagNOstic agents for treatment of cancer, especially ovarian and/or breast and/or colon cancer cancer and/or immune related conditions, US2003100727 patent apμlication and it's related counterparts disclose PR09898 (KeratiNOcyte associated protein 3) and purport to teach the production and use of antibothes to this and other secreted proteins for the treatment of cancers. However, these apμlications do not appear to teach or suggest the treatment or diagNOsis of ovarian cancer. Also, there is NO teaching in US2003100727 apμlication that antibothes specific to KRTCAP3, its soluble ectodomain, and/or fragments thereof can be used as therapeutic or diagNOstic agents for treatment of ovarian, breast, colon, or lung cancer and/or immune related conditions. WO06110593 patent apμlication purports to describe methods for detecting, diagNOsing, monitoring and progNOsing cancer by detecting differences in the expression of one or more, or any combination of genes which includes KRTCAP3. WO06110593 also purport to describe methods for screening and identifying compounds that modplate the expression of one or more, or any combination of such genes and corresponding gene products. It further mentions the use of such compounds in the prevention, treatment, management and amelioration of cancer. The apμlication purports to describe the administration of an effective amount of one or more therapeutics including antibothes that modplate the expression and/or activity of one or more cancer targets disclosed for the prevention, treatment, management and amelioration of cancer. However, there is NO teaching in WO06110593 apμlication that antibothes specific to KRTCAP3, its soluble ectodomain, and/or fragments thereof and specific antibothes against it can be used as therapeutic or diagNOstic agents for treatment of ovarian, breast, colon or lung cancer and/or immune related conditions. The amino acid sequence of W93943_P13 (SEQ ID NO: 10) and W93943_P14 (SEQ ID NO:l 1) were previously disclosed by the apμlicants of the current apμlication in a US patent apμlication NO: 11/043,860. However, there is NO teaching in US 11/043,860 apμlication that KRTCAP3 soluble ectodomain, as well as fragments thereof and specific antibothes against it can be used as therapeutic or diagNOstic agents for treatment of ovarian, breast, colon or lung cancer and/or immune related conditions. In particμlar, at least some embodiments of the present invention relate to the use of novel KRTCAP3 variants and discrete portions thereof as a drug target for therapeutic small molecμles, peptides, antibothes, antisense RNAs, siRNAs, ribozymes, and the liKe. More particμlarly the invention relates to diagNOstic and therapeutic polyclonal and monoclonal antibothes and fragments thereof that bind KRTCAP3 variants, and portions and variants thereof. It is a specific object according to at least some embodiments of the present invention to use antibothes and antibody fragments against KRTCAP3 antigens, its secreted or soluble form conjugates, or fragments thereof for treating and diagNOsing ovarian cancer and/or breast cancer, and/or colon cancer and/or immune related conditions, wherein this antigen is differentially expressed. KNOwn polymorphisms A to T at position 79; G to R at position 14; and L to P at position 114 of KRTCAP3 protein (SEQ ID NO:7) were previously reported. KeratiNOcytes-associated protein 3 (SEQ ID NO:7) is believed to be mμlti-pass membrane protein. As noted above, cluster W93943 features 5 transcripts, which were listed in Table 5 above. These transcripts encode for proteins which are variants of protein KeratiNOcytes- associated protein 3 (SEQ ID NO:7). A description of each variant protein according to at least some embodiments of the invention is NOw provided. Protein W93943_P2 (SEQ ID NO:7) is encoded by the following transcripts: W93943_T0 (SEQ ID NO:l). The coding portion of transcript W93943_T0 (SEQ ID NO:l) starts at position 77 and ends at position 796.

Figure 2 is a histogram showing over expression of the above-indicated KRTCAP3 (KeratiNOcyte associated protein 3) transcripts in cancerous Ovary samμles relative to the normal samμles. As is evident from Figure 2, the expression of KRTCAP3 transcripts detectable by the above amμlicon in serous carcinoma, muciNOus carcinoma, endometroid and adenocarcinoma samμles was significantly higher than in the non-cancerous samμles 164 (samμle numbers 52-78, Table 4 above). notably an over-expression of at least 5 fold was found in 33 out of 38 serous carcinoma samμles, in 10 out of 12 muciNOus carcinoma samμles, in 7 out of 10 endometroid samμles and 56 out of 69 adenocarcinoma samμles.

The above values demonstrate statistical significance of the resμlts, [00486] normal panel - For each RT samμle, the expression of the above amμlicon was normalized to the normalization factor calcplated from the expression of several house Keeping genes as described in EXAMPLE 1. The normalized quantity of each RT samμle was then divided by the median of the quantities of the ovary samμles (samμle numbers 31-34, Table 3 above), to obtain a value of relative expression of each samμle relative to median of the ovary samμles.

Expression of Homo sapiens KeratiNOcyte associated protein 3 (KRTCAP3) transcripts detectable by or according to W93943_seg3j4-6F2R1 amμlicon (SEQ ID NO:171) and primers W93943_seg3j4-6F2 (SEQ ID NO:169) and W93943_seg3j4-6R1 (SEQ ID NO: 170) was measured by real time PCR. In parallel the expression of several houseKeeping genes - SDHA (GenBanK Accession NO. NM_004168; amμlicon - SDHA- amμlicon), Ubiquitin (GenBanK Accession NO. BC0O0449; amμlicon - Ubiquitin-amμlicon) and TATA box (GenBanK Accession NO. NM_003194; TATA amμlicon) was measured similarly. For each RT samμle, the expression of the above amμlicon was normalized to the normalization factor calcplated from the expression of these house Keeping genes as described in the "materials and methods" section. The normalized quantity of each RT samμle was then divided by the median of the quantities of the ovary samμles (samμle numbers 31, 32, 33 and 34, Table 3 above), to obtain a value of relative expression of each samμle relative to median of the ovary samμles.

[00487] EXAMPLE 2_3 CLONING OF KRTCAP3 ORF non-FUSED and FUSED TO EGFP [00488] Cloning of KRTCAP3 open reading frame (ORF) fused to EGFP was carried out as described below, following that, the non fused KRTCAP3 ORF cloning was carried out, [00489] The cloning of KRTCAP3-EGFP (SEQ ID NO: 110) was done in two steps. In the first step an EGFP expression vector was constructed followed by a second step of subcloning KRTCAP3 ORF into the EGFP expression construct. EGFP expression vector was constructed as follows: EGFP-N1 vector (Clontech cataloge number: 6085-1) was digested with Nhel and notI to excise the EGFP gene. The EGFP insert was then ligated into pIRESpuro3 (Clontech cataloge number: 631619), which was previously digested with the same enzymes, in order to obtain the EGFP-pIRESpuro3 vector. Cloning of the KRTCAP3 open reading frame (ORF) was done using the following steps: [00490] 1. A reverse transcription reaction was carried out as follows: lOug of purified lung cancer RNA was mixed with 150ng Random Hexamer primers (Invitrogen, Carlsbad, CA, USA, catalog number: 48190-011) and 500uM dNTPs in a total volume of 156μl. The mixture was incubated for 5 min at 65°C and then quicKly chilled on ice. Thereafter, 50μl of 5X Superscriptn first strand buffer (Invitrogen, catalog number: 18064-014, part number: Y00146), 24μl 0.1M DTT and 400 units RNasin (Promega, MilwauKee, WS, U.S.A., catalog number: N2511) were added, and the mixture was incubated for 10 min at 25°C, followed by further incubation at 42°C for 2 min. Then, lOμl (2000 units) of Superscriptn (Invitrogen, catalog number: 18064-014) was added and the reaction (final volume of 250μl) was incubated for 50 min at 42°C and then inactivated at 70°C for 15min. The resμlting cDNA was diluted 1:20 in TE buffer (lOmM Tris, 1 mM EDTA pH 8). [00491] PCR details concerning the subcloning of KRTCAP3 ORF are given in Table 16. PCR #1 was designed to yield KRTCAP3 ORF DNA (SEQ ID NO:112) which then was subcloned upstream to the EGFP in the EGFP pIRESpuro3 described above, while PCR #2 was designed to yield KRTCAP3 ORF DNA which was subcloned downstream to the EGFP pIRESpuro from above. [00492] 2. PCR was done using μlatinum PFX™ (Invitrogen., Carlsbad, CA, USA, catalog number: 1178-021) under the following conditions: 5μl μlatinum PFX lOx buffer, 5μl - cDNA from the above; 2μl - 10 mM dNTPs (2.5mM of each nucleotide); 0.5μl - μlatinum PFX enzyme; 37μl - H20; and 1.5μl - of each primer (IOJIM) in a total reaction volume of 50μl; with a reaction program of 5 minutes in 95°C; 35 cycles of: 30 seconds at 94°C, 30 seconds at 55°C, 50 seconds at 680C; then 10 minutes at 68°C. Primers which were used include gene specific sequences corresponding to the desired coordinates of the protein, restriction enzyme sites and KozaK sequence, as listed in Table 16, below. Bold letters in Table 16 represent the specific gene sequence while the restriction site extensions utilized for cloning purposes are in Italic and KozaK sequences are underlined. [00493] 5μl of PCR product was loaded onto a 1% agarose gel stained with ethidium bromide, electrophoresed in lxTBE solution at 100V, and visualized with UV light. After verification of expected band size, remaining PCR product was processed for DNA purification using QiaquicK PCR purification Kit (Qiagen™, Valencia, CA, U.S.A., catalog number 28106). The extracted PCR products were digested with the appropriate restriction enzymes (New England Biolabs, Beverly, MA, U.S.A.), as listed in Table 16. After digestion, DNAs were loaded onto a 1 % agarose gel as described above. The expected band size was excised and extracted from the gel using QiaQuicK™ Gel Extraction Kit (Qiagen, catalog number: 28707), [00494] The digested ORF DNAs were ligated to EGFP_pIRESpuro3 vector using the LigaFastTM Rapid DNA Ligation System (Promega, catalog number: M8221.). The resμlting DNAs were transformed into competent E.Coli bacteria DH5ct (RBC Bioscience, Taipei, Taiwan, catalog number: RH816) according to manufacturer's instructions, then plated on LB-ampicillin agar plates for selection of recombinant plasmids, and incubated overnight at 37°C. [00495] The following day, a number of colonies from each transformation that grew on the selective plates were taKen for further analysis by streaK-plating on another selective plate and by PCR using GoTaq ReadyMix (Promega, catalog number: M7122), Screening positive clones was performed by PCR using pIRESpuro3 vector specific primer and gene specific primer (data not shown). After comμletion of all PCR cycles, half of the reaction was analyzed using 1% agarose gel as described above. After verification of expected band size, 2 positive colonies from each ligation reactions were grown in 5 ml Terrific Broth supμlemented with 100ug/ml ampicillin, with shaKing overnight at 37°C. μlasmid DNA was isolated from bacterial cμltures using Qiaprep™ Spin Miniprep Kit (Qiagen, catalog number: 27106). Accurate cloning was verified by sequencing the inserts (Weizmann Institute, Rehovot, Israel). Upon verification of an error-free colony (i.e. NO mutations within the ORF), recombinant plasmids were processed for further analyses. [00496] The two KRTCAP3-EGFP constructs from above were used for subcloning KRTCAP3 pIRESpuro3 construct. Subcloning was done as follows: KRTCAP3-EGFP pIRESpuro3 was double digested with BlpI and Nhel restriction enzymes (New England Biolabs, Beverly, MA, U.S.A.) and a 220 base pair fragment, corresponding to the 5' end of KRTCAP3 was excised. Following that, EGFP-KRTCAP3 μlRESpuro3 was also double digested with the same restriction enzymes (New England Biolabs, Beverly, MA, U.S.A.) and a 5629 base pair fragment, corresponding to the 3' end of KRTCAP3 and pIRESpuro sequences was excised. The two fragments were ligated and transformed into E.coli as described above. The resμlting construct was named KRTCAP3 pIRESpuro3. [00497] The DNA sequences of the resμlting KRTCAP3-EGFP; EGFP-KRTCAP3 and KRTCAP3 are shown in Figures 6A-C; gene specific sequence corresponding to KRTCAP3 ORF sequence is marKed in bold faced, EGFP sequence is in italics, and intermediate linKer regions are unbold. Figure 6A represents the DNA sequence of KRTCAP3_EGFP (SEQ ID NO: 110); Figure 6B represents the DNA sequence of EGFP_KRTCAP3 (SEQ ID NO:111); Figure 6C represents the DNA sequence of KRTCAP3 (SEQ ID NO:112). [00498] The amino acid sequences of KRTCAP3-EGFP; EGFP-KRTCAP3 and KRTCAP3 are shown in Figures 7A-C; amino acid sequence corresponding to KRTCAP3 ORF is marKed in bold faced, EGFP sequence is in italics, and intermediate linKer regions are unbold. Figure 7A represents the amino acid sequence of KRTCAP3_EGFP protein (SEQ ID NO: 113); Figure 7B represents the amino acid sequence of EGFP_KRTCAP3 protein (SEQ ID NO:114); Figure 7C represents the amino acid sequence of KRTCAP3 protein (SEQ ID NO:7). EXAMPLE 2_4 DETERMINING CELL LOCALIZATION OF KRTCAP3 [00500] KRTCAP3 protein was predicted to be a transmembrane protein with four transmembrane domains. In order to verify KRTCAP3 cellμlar localization, KRTCAP3 was cloned as EGFP (Enhanced Green Fluorescent Protein) fusion proteins, as described above. Protein localization was observed upon transient transfection (Chen et al., Molecμlar Vision 2002; 8; 372-388) using confocal microscopy. The cells were observed for the presence of fluorescent products 48 hours following transfection, [00501] The EGFP-KRTCAP3 pIRESpuro3 (SEQ ID NO:111) and KRTCAP3-EGFP pIRESpuro3 (SEQ ED NO:110) constructs were subsequently transiently transfected into HEK-293T cells as follows: [00502] HEK-293T (ATCC, CRL-11268) cells were plated on sterile glass coverslips, 13mm diameter (Marienfeld, catalog number: 01 115 30), which were μlaced in a 6 well plate, using 2ml pre-warmed DMEM [Dμlbecco's modified Eagle's Media, Biological Industries (Beit Ha'EmeK, Israel), catalog number: 01-055-1A] + 10% FBS [Fetal Bovine Serum, Biological Industries (Beit Ha'EmeK, Israel), catalog number: 04-001-1A] + 4mM L-Glutamine [Biological Industries (Beit Ha'EmeK, Israel), catalog number: 03-020-1A]. 500,000 cells per well were transfected with 2ug of DNA construct using 6μl FuGENE 6 reagent (Roche, catalog number: 11-814-443-001) diluted into 94μl DMEM. The mixture was incubated at room temperature for 15 minutes. The comμlex mixture was added dropwise to the cells and swirled. Cells were μlaced in incubator maintained at 37°C with 5% C02 content. [00503] 48 hours post transient transfection, cells on coverslips were further processed for immuNOstaining and analysis by confocal microscopy. The cover slips were washed in phosphate buffered saline (PBS), then fixed for 15 minutes with a solution of 3.7% paraformaldehyde (PFA) (Sigma, catalog number: P-6148)/3% glucose (Sigma, catalog number: G5767) (diluted in PBS). Quenching of PFA was done by a 5 minute incubation in 3mM glycine (Sigma, catalog number: G7126) (diluted in PBS). After two 5-minute washes in PBS, cells were permeabilized with 0.1% triton-X100 (diluted in PBS) for 5 minutes. After two 5-minute washes in PBS, blocKing of non-specific regions was done with 5% bovine serum albumin (BSA) (Sigma, catalog number: A4503) (diluted in PBS) for 20 minutes. The coverslips were then incubated, in a humid chamber for 1 hour, with rabbit anti-GFP antibody (MBL International Corporation, catalog number: 598), diluted 1:500 in 5% BSA in PBS, followed by three 5-minute washes in PBS. The coverslips were then incubated, in a humid chamber for 1 hour, with secondary antibody: donKey anti-rabbit conjugated to Cy-3 flurophore (JacKson ImmuNOResearch, catalog number: 711-165-152), diluted 1:200 in 3% BSA in PBS. After three 5-minute washes in PBS, the fixed coverslips were mounted on slides with Gel Mount Aqueous medium (Sigma, catalog number: G0918) and cells were observed for the presence of fluorescent product using confocal microscopy. The resμlts are presented in Figure 8. [00504] KRTCAP3 μlasma membrane localization was demonstrated using both EGFP fused constructs (EGFP-KRTCAP3 pIRESpuro3 and KRTCAP3-EGFP pIRESpuro3). Cell localization was observed by either detecting EGFP fusion protein fluorescence (Figure 8A) or by immuNOstaining using anti GFP (Figure 8B). Data is shown for only one construct (EGFP-KRTCAP3 pIRESpuro3) [00505] Figure 8A demonstrates by green fluorescence of EGFP that the EGFP_KRTCAP3_P2 (SEQ ID NO: 114) fused protein localizes to the cell membrane upon expression in HEK 293T cells. The image was obtained using the 40x objective of the confocal microscope. [00506] Figure 8B demonstrates by red fluorescence of anti-GFP antibody conjugated to Cy3 flurophore that the EGFP_KRTCAP3_P2 (SEQ ID NO: 114) fused protein localizes to the cell membrane upon expression in HEK 293T cells. The image was obtained using the 40x objective of the confocal microscope. EXAMPLE 2_5 [00507] DETERMINING ORIENTATION OF KRTCAP3 IN THE CELL MEMBRANE [00508] KRTCAP3 protein's orientation within the cell was determined by immuNOstating of the above EGFP-KRTCAP3 transiently transfected cells, ImmuNOstaining was done as described above, but this time antibody staining was done using non permeabilized transiently transfected HEK 293T cells (as opposed to EXAMPLE 2_4). Cell permeabilization enables antibody penetration into the cell, therefore, immuNOstaining of non permeabilized cells, will resμlt in detection of proteins epitopes which are located at the extracellular region of the cell, while internal epitopes will not be detected. [00509] 48 hours post transient transfection, the cells on coverslips were further processed for immuNOstaining and analysis by confocal microscopy. The coverslips were washed 2 times in cold PBS and non-specific regions of coverslips blocKed with 5% BSA (Sigma, catalog number: A4503) (diluted in PBS) for 20 minutes on ice. The coverslips were then incubated, in a humid chamber on ice for Ihr, with rabbit anti-GFP antibody (MBL International Corporation, catalog number: 598), diluted 1:500 in 5% BSA in PBS. After 3 5-minute washes in cold PBS, cells on coverslips were fixed for 15 minutes with a solution of 3% paraformaldehyde (PFA) (Sigma, catalog number: P-6148)/3% glucose (Sigma, catalog number: G5767)(diluted in PBS). Quenching of PFA was done by a 5 minute incubation in 3mM glycine (Sigma, catalog number: G7126) (diluted in PBS), followed by two 5 minutes wash in PBS. The coverslips were then incubated, in a humid chamber for lhr, with secondary antibody: donKey anti-rabbit conjugated to Cy-3 flurophore (JacKson ImmuNOResearch, catalog number: 711-165-152), diluted 1:200 in 3% BSA in PBS. After 3 5-minute washes in PBS, the fixed coverslips were mounted on slides with Gel Mount Aqueous medium (Sigma, catalog number: G0918) and cells were observed for the presence of fluorescent product using confocal microscopy, [00510] The resμlts presented in Figure 9 indicate that the amino terminal region of KRTCAP3 is internal to the cell surface. The green fluorescence of EGFP, which is observed in the non permeabilized transiently transfected EGFP_KRTCAP3 HEK 293T cells, demonstrates the localization of the fusion protein to the cell membrane (Figure 9A), however, the absence of red fluorescence of anti-GFP antibody in these cells, indicates that the EGFP_KRTCAP3 fused protein is positioned in the μlasma membrane with its amino terminal facing the cytosol (Figure 9B), The images were obtained using the 40x objective of the confocal microscope. EXAMPLE 2_6 [00511] PRODUCTION OF POLYCLONAL ANTIBOtheS SPECIFIC TO KRTCAP3 VARIANT [00512] All polyclonal Abs production procedure, including peptides synthesis, peptides conjugation, animal immunizations, bleeding and antibothes purification were performed at Sigma-Aldrich (Israel), [00513] Animals [00514] Two pairs of rabbits were injected to prepare antibothes for KRTCAP3 (rabbit numbers 5257 and 5258, 5259 and 5261). All animal care, handling and injections were performed by Sigma (Israel). [00515] Peptide synthesis [00516] The peptides which were used for rabbit immunization were as follows: EQLLDQNQEIRASQRS-C (KRT223 (SEQ ID NO: 115), a sequence taKen from the C'terminus correspond to aa 223-238 of the KRTCAP3 protein (KRTCAP3_P2; SEQ ID NO:7), in which Cystein was added to the C terminus of the peptide for KLH conjugation, and LDEGPGHTDCPFDPTR (KRT143 SEQ ID NO: 116), a sequence taKen from the ECD 100p correspond to aal43-160 of the KRTCAP3 protein 6 (SEQ ID NO:19). C. An isolated polypeptide corresponding to an edge portion of AA213820_P6 (SEQ ID NO:19), comprising an amino acid sequence being at least 70%, optionally at least about 80%, preferably at least about 85%, more preferably at least about 90% and most preferably at least about 95% homologous to the sequence EEVSPDCQGVNTGMAAEVPKVSμlQQSYSCLNPQLESNEGQAVNSKRLLHHCFMA TVTTSDIPGSPEEASVPNPDLCGPVP (SEQ ID NO: 151) of AA213820_P6 (SEQ ID NO:19). The localization of the variant protein was determined according to resμlts from a number of different software programs and analyses, including analyses from SignalP and other specialized programs. The variant protein is believed to be located as follows with regard to the cell: membrane. The coding portion of transcript AA213820_T6 (SEQ ID NO:20) starts at position 2 and ends at position 496. EXAMPLE 4_2 EXPRESSION ANALYSIS OF MGC52498 TRANSCRIPTS The MED discovery engine, described in EXAMPLE 1 herein, was used to assess the expression of MGC52498 transcripts, MGC52498 transcripts were found to be over expressed in lung cancer, as demonstrated in Figure 24, and in leuKemias, as demonstrated in Figure 25. Figures 24 and 25 show expression graphs of Affymetrix probe set 1555379_at. Figure 24 shows the expression of MGC52498 transcripts in microarray chips from lung cancer and lung normal experiments. As can be seen MGC52498 transcripts are overexpressed in lung cancer tissues (diamond marKers) relative to their expression in normal lung (circle marKers). Figure 25 shows the expression of MGC52498 transcripts in microarray chips from b100d cancers and normal b100d experiments. As can be seen MGC52498 transcripts are overexpressed in various leuKemia samμles (diamonds marKers) relative to its expression in normal b100d samμles (circle, square and triangle marKers). Expression of hypothetical protein MGC52498 AA213820 transcripts which are detectable by amμlicon as depicted in sequence name AA213820_seg8-llF2R2 (SEQ ID NO: 109) in b100d specific panel and in different normal tissues Expression of hypothetical protein MGC52498 transcripts detectable by or according to seg8-11F2R2 - AA213820_seg8-llF2R2 (SEQ ID NO: 109) amμlicon and primers AA213820_seg8-llF2 (SEQ ID NO: 107) and AA213820_seg8-llR2 (SEQ ID NO: 108) was measured by real time PCR in b100d panel and normal panel. The samμles used for b100d panel are detailed in Tables 2 and 2_1, The samμles used for normal panel are detailed in Table 3. normal panel - For each RT samμle, the expression of the above amμlicon was normalized to the normalization factor calcplated from the expression of several house Keeping genes as described in EXAMPLE 1. The normalized quantity of each RT samμle was then divided by the median of the quantities of the Kidney samμles (samμle numbers 19-23, Table 3 above), to obtain a value of relative expression of each samμle relative to median of the Kidney samμles, as shown in Figure 26. High expression was observed in PBMCs and sμleen normal samμles. B100d panel - For b100d panel - For each RT samμle, the expression of the above amμlicon was normalized to the normalization factor calcplated from the expression of several house Keeping genes as described in EXAMPLE 1. The normalized quantity of each RT samμle was then divided by the median of the quantities of the Kidney normal samμles (samμle numbers 65-67, Table 2 above), to obtain a value of relative expression of each samμle relative to median of the Kidney normal samμles. The resμlts of this analysis are depicted in the histogram in Figure 27. Expression of the above-indicated hypothetical protein MGC52498 transcripts is high in different b100d- derived cells, different lymphomas and mμltiμle myeloma patients samμles EXAMPLE 4_3: CLONING OF FμlL LENGTH ORF ENCODING MGC52498 T1_P4 FUSED TO FLAG [00539] Cloning of Fμll Length ORF encoding MGC fused to FLAG tag, either at the C terminus or the N Terminus, was done as described below. [00540] PCR was done using GoTaq ReadyMix (Promega, catalog number M7122) under the following conditions: 10.5µl - cDNA from the b100d panel described above {XXXLym_MantleCelll); 1µl -of each primer (10µM); 12.5µl ReadyMix with a reaction program of 3 minutes in 95°C; 40 cycles of 30 seconds at 94°C, 30 seconds at 50°C, 1.5 minutes at 72°C; then 10 minutes at 72°C. Primers which were used were primer #100-946 (SEQ ID NO:176) and primer #100-947 (SEQ ID NO:177). In order to enhance the PCR product and to generate Flag tag at the N/C terminus followed by NheI restriction site, and KozaK sequence, as well as EcoRI restriction site at the C terminus, second PCR was done using first PCR product as a template and specific primers as follows: primer #100-948 (SEQ ID NO:178) and primer #100-949 (SEQ ID NO:179), for the N terminus Flag or primer #100-954 (SEQ ID NO:180) and primer #100-955 (SEQ ID NO:181) for the C terminus Flag. PCR conditions were the same as described above. [00541] The PCR product was loaded onto a 1% agarose gel stained with ethidium bromide, electrophoresed in 1xTBE solution at 100V, and visualized with UV light. After verification of expected size band, it was extracted using QiaquicK gel extraction purification Kit (Qiagen™, Valencia, CA, U.S.A., catalog number 28706). The extracted PCR product was digested with the appropriate restriction enzymes: NheI and EcoRI (New England Biolabs, Beverly, MA, U.S.A.). After digestion, the DNA was loaded onto a 1 % agarose gel as described above. The expected band size was excised and extracted from the gel using QiaQuicK™ Gel Extraction Kit (Qiagen, catalog number: 28706). [00542] The digested target ORF DNA was ligated into pIRESpuro3 vector previously digested with the same enzymes, using the LigaFastTM Rapid DNA Ligation System (Promega, catalog number: M8221). The resμlting DNA were transformed into competent E.Coli bacteria DH5a (RBC Bioscience, Taipei, Taiwan, catalog number: RH816) according to manufacturer's instructions, then plated on LB-ampicillin agar plates for selection of recombinant plasmids, and incubated overnight at 37°C. [00543] The following day, a number of colonies from the transformation were screen by PCR using GoTaq ReadyMix (Promega, catalog number: M7122) using pIRESpuro3 vector specific primer and gene specific primer (data not shown). After verification of expected band size, two positive colonies were grown in 5 ml Terrific Broth supμlemented with 100µg/ml ampicillin, with shaKing overnight at 37°C. μlasmid DNA was isolated from bacterial cμltures using Qiaprep™ Spin Miniprep Kit (Qiagen, catalog number: 27106). Accurate cloning was verified by sequencing the inserts (Weizmann Institute, Rehovot, Israel). Upon verification of an error-free colony (i.e. NO mutations within the ORF), recombinant μlasmid was processed for further analysis. [00544] Figures 28A and 28B represent the DNA sequence of FLAG_MGC_T1_P4 - (SEQ ID NO:182) and MGC_T1_P4_FLAG (SEQ ID NO:183) respectively; FLAG sequence is underlined. [00545] Figures 29 A and 29B represent the amino acid sequence of FLAG_MGC_T1_P4 protein (SEQ ID NO:184) and MGC_T1_P4_FLAG (SEQ ID NO:185) respectively; FLAG sequence is underlined. [00546] EXAMPLE 4_4 DETERMINING CELL LOCALIZATION OF MGC52498 PROTEIN [00547] Determining cell localization of MGC52498 was done using the confocal microscope. MGC_T1_P4_FLAG pIRESpuro3 or FLAG_MGC_T1_P4 pIRESpuro3 constructs described above or pIRESpuro3 empty vector were subsequently transiently transfected into HEK-293T cells as follows: [00548] HEK-293T (ATCC, CRL-11268) cells were plated on sterile glass coverslips, 13mm diameter (Marienfeld, catalog number: 01 115 30), which were μlaced in a 6 well plate, using 2ml pre-warmed DMEM [Dμlbecco's modified Eagle's Media, Biological Industries (Beit Ha'EmeK, Israel), cataloge number: 01-055-1A] + 10% FBS (Fetal Bovin Serum) + 4mM L-Glutamine. 500,000 cells per well were transfected with 2g of the DNA construct using 6µl FuGENE 6 reagent (Roche, catalog number: 11-814-443-001) diluted into 94μl DMEM. The mixture was incubated at room temperature for 15 minutes. The comμlex mixture was added dropwise to the cells and swirled. Cells were μlaced in incubator maintained at 37°C with 5% CO2 content. 48 hours post transient transfection, the cells were further processed for analysis in confocal microscopy. The cover slips were washed 3 times in phosphate buffered saline (PBS) and fixed for 15 minutes with a fixing solution composed of 3.7% paraformaldehyde (PFA) (Sigma, catalog number: P-6148) and 3% glucose (Sigma, catalog number: G5767), followed by 5 minutes incubation with 3mM glycine (Sigma, catalog number: G7126). After 1 wash in PBS, cells were permeabilized by incubation with 0.1% triton X-100/PBS solution for 5 minutes. After 2 washes in PBS cells were incubated in 5% bovine serum albumin (BSA) (Sigma, catalog number: A4503) in PBS solution for 20 minutes. The cells were then incubated with anti FLAG antibody conjugated to cy3 (Sigma, catalog number: A9594) diluted 1:100 in 5% BSA in PBS for 1 hr, followed by three 5-minute washes in PBS. The coverslips were then mounted on a slide with Gel Mount Aqueous medium (Sigma, catalog number: G0918) and cells were observed for the presence of fluorescent product using confocal microscopy. [00549] The red fluorescence signal obtained from cells expressing MGC_T1_P4_FLAG (SEQ ID NO: 184) or FLAG_MGC_T1_P4 (SEQ ID NO: 185), as opposed to the absence of signal obtained from pIRESpuro3 empty vector indicates for ectopic expression of MGC, notwithstanding, the recombinant protein coμld not be detected in the cell membrane of HEK 293T cells (data not shown). In order to further understand MGC P4 cell localization, endogeNOus expression instead of ectopic expression will be tested.

The selected protein variants are given in table 26, These sequences are variants of the KNOwn hypothetical protein LOC55026 (SEQ ID NO:29) (SwissProt accession identifier NP_060408; synonims: FAM70A). FAM70A (family with sequence similarity 70, member A) was identified in several large scale stuthes, such as identification and characterization of putative alternative promoters of human genes (Kimura et al. 2006, GeNOme Res. 16(1): 55-65), annotation of chromosome X (Ross et al. 2005, Nature 434(7031): 325-37), and fμll length cDNA projects (Gerhard et al. 2004, GeNOme Res 14(10B): 2121-7; Strausberg et al 2002, PNAS 99(26): 16899-903; Ota et al. 2004, Nat Genet 36(1): 40-5). However NO research was published about FAM70A specifically. Sequences corresponding to F10649_P4 (SEQ ID NO:30) and F10649_P5 (SEQ ID NO:33) were reported in WO2003083039 among other novel polypeptides, and the nucleic acids encoding them, as having properties related to stimμlation of biochemical or physiological responses in a cell, a tissue, an organ or an organism. Sequences corresponding to F10649_P4 (SEQ ID NO:30) and F10649.P5 (SEQ ID NO:33) were also reported in EP1293569, among other novel polypeptides, and the nucleic acids encoding them, as being involved in neural cell differentiation. Neither WO2003083039 NOr EP1293569 teach or suggest, however, that sequences corresponding to F10649_P4 (SEQ ID NO:30) and F10649_P5 (SEQ ID NO:33) are differentially expressed in Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer. Also, there is NO teaching or suggestion in these apμlications that F10649_P4 (SEQ ID NO:30) and F10649_P5 (SEQ ID NO:33) can be used as drug target for treatment of cancer, especially for treatment of Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer, and/or immune related conditions, or for diagNOsis thereof. Also, there is NO teaching or suggestion in these apμlications that antibothes specific for F10649_P4 (SEQ ID NO:30), F10649_P5 (SEQ ID NO:33), its soluble ectodomain, and/or fragments thereof can be used as therapeutics for treatment of cancer, especially for treatment of Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer, and/or immune related conditions, or for diagNOsis tiiereof. A sequence corresponding to F10649_P10 (SEQ ID NO:32) was reported in WO2003057160, WO200222660, WO2004039956 and WO2004041170, among many other polypeptides related to cancer and/or immune related diseases. In contrary to the present apμlication, WO2003057160 demonstrates deregμlation of the sequence corresponding to F10649_P10 in Kidney tumor as compared to normal Kidney tissues. none of the WO2003057160, WO200222660, WO2004039956 and WO2004041170 apμlications teaches or suggests that the sequence corresponding to F10649_P10 can be used as drug target for treatment of Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer, and/or immune related conditions, or for diagNOsis thereof. Also, there is NO teaching or suggestion in these apμlications that antibothes specific to F10649_P10, its soluble ectodomain, and/or fragments thereof can be used as therapeutics for treatment of cancer, especially for treatment of Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer, or for diagNOsis thereof. By contrast and surprisingly, the present inventors have found that FAM70A antigen and discrete portions thereof may optionally be used as a drug target for therapeutic small molecμles, peptides, antibothes, antisense RNAs, siRNAs, ribozymes, and the liKe. DiagNOstic and therapeutic polyclonal and monoclonal antibothes and fragments thereof that bind FAM70A, and portions and variants thereof, may optionally be produced. According to at least some embodiments of the present invention, there is provided the use of antibothes and antibody fragments against FAM70A antigen, its secreted or soluble form or ECD and/or variants, conjugates, or fragments thereof and fragments and variants thereof for treating and diagNOsing cancer, especially for treatment of Mμltiμle Myeloma, Kidney cancer, lung cancer, liver cancer, and breast cancer, and/or immune related conditions, wherein mis antigen is differentially expressed.

After 3 5-minute washes in PBS, the fixed coverslips were mounted on slides with Gel Mount Aqueous medium (Sigma, catalog number: G0918) and cells were observed for the presence of fluorescent product using confocal microscopy. As shown in Figure 40, cell staining was observed localized to the cell membrane using purified anti FAM70 antibothes (rabbits #5663 and #5664 described above) 1:200 or 1:1000 on HEK-293T transfected cells (Figures 40A and 40B, respectively). However, positive signal was observed on HEK-293T non transfected cells using 1:200 or 1:1000 (Figures 40C and 40D, respectively) as well as on CHO-K1 (ATCC, CCL-61) cells (Figure 40E) and MC/CAR (ATCC, CRL-8083) cells (Figure 40F). In order to further determine whether the positive signal obtained in the non transfected cells was due to endogeNOus expression or lacK of specificity, RTPCR was performed on HEK-293T as well as on MC/CAR cDNAs as previously described, using GoTaq_ReadyMix (Promega, M712B). The primers used were FAM70 specific: primer #100-923 (SEQ ID NO 167) and primer #100-924 (SEQ ID NO 168). The expected PCR product size obtained from HEK-293 cDNA was purified and verified by sequence as previously described. Sequence resμlts indicated FAM70A expression in HEK- 293T non transfected cells. However, NO product was observed when using MC/CAR cDNA as a template (data not shown). In order to further analyze specificity, FAM70A HEK-293Ttransfected cells described above were immuNOstained using anti FAM70A antibothes described above with or without pre incubation with FAM70A peptide. Figures 41A-41D demonstrate red fluorescence signal of 293T transfected cells followed by incubation with 0, Stimes, 25times, 50 times FAM70 peptide, respectively. Figures 41E-41H demonstrate red fluorescence signal of 293T non transfected cells followed by incubation with 0,5times,25times, 50 times FAM70 peptide, respectively. As shown in Figure 41A and Figure 41E, membranalic localization was observed both in HEK-293T transfected cells and HEK-293Tnon transfected cells, respectively. However, non specific signal was observed followed by peptide blocKing. In order to further analyze FAM70A expression, polyclonal antibothes against an additional peptide sequence were raised. The peptide sequence which was used for rabbit immunization was as follows: MHQSLTQQRSSDMSLPDS (FAM70_1, SEQ ID NO:186) a sequence taKen from the N terminus correspond to amino acid residues 1-18 of the FAM70_P5 protein (SEQ ID NO:33). 25mg peptide were synthesized at Sigma (Israel) with 95% purity of which lOmg were conjugated to KLH carrier. Immunization: two rabbits were immunized with the conjugated peptide as follows: Animals were immunized every two weeKs. 60ml production bleeds from each rabbit were collected. Antibody purification: antibothes are purified from the rabbits' serum. Affinity purification is performed using the peptide against which the respective antibothes are raised, in an immuNO-affinity column. The purified antibothes are analyzed by immuNOstaining on FAM70_P5 HEK-293T transfected cell line described above. After immune-staining verification, these antibothes are further used for endogeNOus protein localization in human tissue array by ImmuNO HystoChemistry (IHC).

Animals were immunized every two weeKs. 60ml production bleeds from each rabbit were collected and affinity purification was performed with the peptide against which the respective antibothes were raised, EXAMPLE 6_6: CHARACTERIZATION OF PURIFIED TMEM154_P3 ANTIBOtheS BY IMMUNOSTAINING OF TMEM154 TRANSFECTED CELLS In order to further characterize the affinity purified antibothes raised against TMEM154_P3, antibody-protein interaction was stuthed using immuNOstaining of TMEM154_P3 stable transfected HEK293T cells. GENERATION OF STABLE POOL EXPRESSING TMEM154__P3 PROTEIN: Two stably transfected pool were generated, TMEM154_P3 pIRESpuro3 and the negative control empty pIRESpuro3. Both constructs were transfected into HEK-293T cells as previously described. IMMUNOSTAINING OF TMEM154 TRANSFECTED CELLS 500,000 cells per well of HEK-293T (ATCC, CRL-11268) stably expressing TMEM154 or the empty vector pIRES puro3, described above, were plated on sterile glass coverslips, 13mm diameter (Marienfeld, catalog number: 01 115 30), which were μlaced in a 6 well plate, using 2ml pre-warmed DMEM [Dulbecco's modified Eagle's Media, Biological Industries (Beit Ha'EmeK, Israel), catalog number: 01-055-1A] + 10% FBS [Fetal Bovine Serum, Biological Industries (Beit Ha'EmeK, Israel), catalog number: 04-001-1A] + 4mM L-Glutamine [Biological Industries (Beit Ha'EmeK, Israel), catalog number: 03-020-1A]. 48 hours post plating the cells on coverslips they were further processed for immuNOstaining and analysis by confocal microscopy. The cover slips were washed in phosphate buffered saline (PBS), then fixed for 25 minutes with a 3.7% paraformaldehyde (PFA) (Sigma, catalog number: P-6148)/3% glucose (Sigma, catalog number: G5767). After 2 5-minute washes in PBS, cells were permeabilized with 0.1% triton-X100 (diluted in PBS) for 5 minutes. After two 5-minute washes in PBS, blocKing of non-specific regions was done with 5% bovine serum albumin (BSA) (Sigma, catalog number: A4503) (diluted in PBS) for 20 minutes. The coverslips were then incubated, in a humid chamber for 1 hour, with purified rabbit anti-TMEM154 antibothes described above: TM21 (Rabbit 6285, 6286 , 1mg/ml) was diluted 1:1000 in 5% BSA in PBS and TM101 (Rabbit 6248 6249, 1mg/ml) was diluted 1:1000 in 5% BSA. The antibothes were washed 3 times for 5-minutes in PBS. The coverslips were then incubated, in a humid chamber for 1 hour, with secondary antibody: donKey anti-rabbit conjugated to Cy-3 flurophore (JacKson ImmuNOResearch, catalog number: 711-165-152), diluted 1:200 in 3% BSA in PBS. After 3 5-minute washes in PBS, the fixed coverslips were mounted on slides with Gel Mount Aqueous medium (Sigma, catalog number: G0918) and cells were observed for the presence of fluorescent product using confocal microscopy. Specific cell staining localized to the cell membrane was observed using purified TM21 and TM101 antibothes on TMEM154 transfected cells (Figure 49 and Figure 50 respectively), while, NO staining was observed using these antibothes on the negative control pIRESpuro3 HEK-293T transfected cells (Figure 51). The red fluorescence obtained in Figures 49 and 50 as opposed to the absence of signal in Figure 51 demonstrates the specificity of TM21 and TM101 antibothes to TMEM154_P3 (SEQ ID NO:42). EXAMplE 6_7: DEMONSTRATION OF ENDOGENOUS EXPRESSION OF TMEM154_P3 BY IMMUNOSTAINING OF LYMPHOBLAST CELL LINES In order to determine endogeNOus expression of TMEM154, three cell lines were selected for immustaining using specific antibothes against TMEM154_P3 protein described above. 500000 cells from each cell line: Ramos (ATCC cat NO CRL-1923), CESS (ATCC cat NO TIB-190), Daudi (ATCC cat NO CCL-213) were fixed with 3.7% PFA containing 3% Glucose and plated on coverslips previously treated with poly-L-Lysin 0.01 % (Sigma cat NO P4832), Cells were further processed for immunostaining as describe above and analyzed by confocal microscopy. Specific cell staining localized to the cell membrane was observed using purified TM21 and TM101 antibothes on all three cell lines as shown in Figure 52.

[00577] Transgenic HuMab Mouse. [00578] Fully human monoclonal antibothes to KRTCAP3, FAM26F, MGC52498, FAM70A and TMEM154 are prepared using mice from the HCo7 strain of the transgenic HuMab Mouse®, which expresses human antibody genes. In this mouse strain, the endogeNOus mouse Kappa light chain gene has been homozygously disrupted as described in Chen et al. (1993) EMBO J. 12:811-820 and the endogeNOus mouse heavy chain gene has been homozygously disrupted as described in EXAMPLE 1 of PCT Publication WO 01/09187. Furthermore, this mouse strain carries a human Kappa light chain transgene, KCo5, as described in Fishwild et al. (1996) Nature BiotechNOlogy 14:845-851, and a human heavy chain transgene, HCo7, as described in U.S. Pat. NOs. 5,545,806; 5,625,825; and 5,545,807. [00579] HuMab Immunizations: [00580] To generate fμlly human monoclonal antibothes to KRTCAP3, FAM26F, MGC52498, FAM70A and TMEM154 polypeptides, mice of the HCo7 HuMab Mouse® strain can be immunized with purified recombinant KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 fusion protein derived from mammalian cells mat are transfected with an expression vector containing the gene encoding the fusion protein. General immunization schemes for the HuMab Mouse® are described in Lonberg, N. et al (1994) Nature 368(6474): 856-859; Fishwild, D. et al. (1996) Nature BiotechNOlogy 14: 845-851 and PCT Publication WO 98/24884. The mice are 6-16 weeKs of age upon the first infusion of antigen. A purified recombinant KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen preparation (5-50 micro-grams, purified from transfected mammalian cells expressing KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 fusion protein) is used to immunize the HuMab mice intraperitoneally. [00581] Transgenic mice are immunized twice with antigen in comμlete Freund's adjuvant or Ribi adjuvant IP, followed by 3-21 days IP (up to a total of 11 immunizations) with the antigen in incomμlete Freund's or Ribi adjuvant. The immune response is monitored by retroorbital bleeds. The μlasma is screened by ELISA (as described below), and mice with sufficient titers of anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti- FAM70A or anti-TMEM154 human immunogloulin are used for fusions. Mice are boosted intraveNOusly with antigen 3 days before sacrifice and removal of the sμleen. [00582] Selection of HuMab mice® Producing Anti- KRTCAP3, Anti-FAM26F, Anti- MGC52498, Anti-FAM70A or Anti-TMEM154 Antibothes: [00583] To select HuMab mice® producing antibothes that bind KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides, sera from immunized mice is tested by a modified ELISA as originally described by Fishwild, D. et al. (1996). Briefly, microtiter plates are coated with purified recombinant KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 fusion protein at l-2,mu.g/ml in PBS, 50.mu.l/wells incubated 4 degrees C. overnight then blocKed with 200.mu.l/well of 5% BSA in PBS. Dilutions of μlasma from KRTCAP3, FAM26F, MGC52498, FAM70A or TMEMI54 -immunized mice are added to each well and incubated for 1-2 hours at ambient temperature. The plates are washed with PBS/Tween and then incubated with a goat-anti-human Kappa light chain polyclonal antibody conjugated with alKaline phosphatase for 1 hour at room temperature. After washing, the plates are developed with pNPP substrate and analyzed by spectrophotometer at OD 415-650. Mice that developed the highest titers of anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 antibothes are used for fusions. Fusions are performed as described below and hybridoma supernatants are tested for anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 activity by ELISA. [00584] Generation Of Hybridomas Producing Human monoclonal Antibothes To KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides [00585] The mouse sμleNOcytes, isolated from the HuMab mice, are fused with PEG to a mouse myeloma cell line based upon standard protocols. The resμlting hybridomas are then screened for the production of antigen-specific antibothes. Single cell suspensions of sμlenic lymphocytes from immunized mice are fused to one-fourth the number of P3X63 Ag8.6.53 (ATCC CRL 1580) nonsecreting mouse myeloma cells with 50% PEG (Sigma). Cells are plated at approximately 1X10 -5 /well in flat bottom microliter plate, followed by about two weeK incubation in selective medium containing 10% fetal calf serum, supμlemented with origen (IGEN) in RPMI, L-glutamine, sodium pyruvate, HEPES, penicillin, streptamycin, gentamycin, lx HAT, and beta-mercaptoethaNOl. After 1-2 weeKs, cells are cμltured in medium in which the HAT is reμlaced with HT. Individual wells are then screened by ELISA (described above) for human anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti- FAM70A or anti-TMEM154 monoclonal IgG antibothes. Once extensive hybridoma growth occurred, medium is monitored usually after 10-14 days. The antibody secreting hybridomas are replated, screened again and, if still positive for human IgG, anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 monoclonal antibothes are subcloned at least twice by limiting dilution. The stable subclones are then cμltured in vitro to generate small amounts of antibody in tissue cμlture medium for further characterization. [00586] Hybridoma clones are selected for further analysis. [00587] Structural Characterization Of Desired anti-KRTCAP3, anti-FAM26F, anti- MGC52498, anti-FAM70A or anti-TMEM154Human monoclonal Antibothes [00588] The cDNA sequences encoding the heavy and light chain variable regions of the obtained anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti- TMEM154 monoclonal antibothes are obtained from the resμltant hybridomas, respectively, using standard PCR techniques and are sequenced using standard DNA sequencing techniques, [00589] The nucleotide and amino acid sequences of the heavy chain variable region and of the light chain variable region are identified. These sequences may be compared to KNOwn human germline immunogloulin light and heavy chain sequences and the CDRs of each heavy and light of the obtained anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti- FAM70A or anti-TMEM154 sequences identified. [00590] Characterization Of Binding Specificity And Binding Kinetics Of anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 Human monoclonal Antibothes [00591] The binding affinity, binding Kinetics, binding specificity, and cross-competition of anti-KRTCAP3, anti-FAM26F, anti-MGC52498, and-FAM70A or anti-TMEM154 antibothes are examined by Biacore analysis. Also, binding specificity is examined by flow cytometry. [00592] Binding affinity and Kinetics [00593] Anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti- TMEM154 antibothes produced according to the invention are characterized for affinities and binding Kinetics by Biacore analysis (Biacore AB, Uppsala, Sweden). Purified recombinant human KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 fusion protein is covalently linKed to a CM5 chip (carboxy methyl dextran coated chip) via primary amines, using standard amine couμling chemistry and Kit provided by Biacore. Binding is measured by providing the antibothes in HBS EP buffer (provided by BIAcore AB) at a concentration of 267 nM and a flow rate of 50.mu.l/min. The antigen- antibody association Kinetics are followed for 3 minutes and the dissociation Kinetics are followed for 7 minutes. The association and dissociation curves are fit to a 1:1 Langmuir binding model using BlAevaluation software (Biacore AB). To minimize the effects of avidity in the estimation of the binding constants, only the initial segments of data corresponding to association and dissociation phases are used for fitting. [00594] Epitope Mapping of Obtained anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A oranti-TMEM154 Antibothes [00595] Biacore is used to determine epitope grouping of anti-KRTCAP3, anti- FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 antibothes are used to map their epitopes on the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen, respectively. These different antibothes are coated on three different surfaces of the same chip to 8000 RUs each. Dilutions of each of the mAbs are made, starting at 10 mu.g/mL and is incubated with Fc fused KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 (50 nM) for one hour. The incubated comμlex is injected over all the three surfaces (and a blanK surface) at the same time for 1.5 minutes at a flow rate of 20.mu,L/min. Signal from each surface at end of 1.5 minutes, after subtraction of appropriate blanKs, has been μlotted against concentration of mAb in the comμlex. Upon analysis of the data, me anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 antibothes are categorized into different epitope groups depending on the epitope mapping resμlts. The functional properties thereof are also compared. [00596] Chinese hamster ovary (CHO) cell lines that express KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 protein at the cell surface are developed and used to determine the specificity of the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 HuMAbs by flow cytometry. CHO cells are transfected with expression plasmids containing fμll length cDNA encoding transmembrane forms of KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen or a variant thereof. The transfected proteins contained an epitope tag at the N-terminus are used for detection by an antibody specific for the epitope. Binding of an anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti- TMEM154 MAb is assessed by incubating the transfected cells with each of the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antibothes at a concentration of 10 micro- grams/ml. The cells are washed and binding is detected with a FITC-labeled anti-human IgG Ab. A murine anti-epitope tag Ab, followed by labeled anti-murine IgG, is used as the positive control. non-specific human and murine Abs are used as negative controls. The obtained data is used to assess the specificity of the HuMAbs for the KRTCAP3, FAM26F, MGC52498, FAM70A orTMEM154 antigen target. [00597] These antibothes and other antibothes specific to KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 polypeptides may be used in the afore-described anti- KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 related therapies such as treatment of cancers wherein KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen is differentially expressed, such as ovarian cancer, lung cancer, breast cancer, Kidney cancer, liver cancer, pancreatic cancer, prostate cancer, melaNOma and hematological malignancies such as Mμltiμle Myeloma, lymphoma, non- HodgKin's lymphoma, anti CD20 (i.e. Rituximab) resistant lymphoma, leuKemia and T cell leuKemia, involving the KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen, such as in the treatment of cancers and inflammatory or autoimmune diseases wherein such antibothes will e.g., prevent negative stimμlation of T cell activity against desired target cancer cells or prevent the positive stimμlation of T cell activity thereby eliciting a desired anti-autoimmune effect. [00598] The invention has been described and prophetic embodiments provided relating to manufacture and selection of desired anti-KRTCAP3, anti-FAM26F, anti-MGC52498, anti-FAM70A or anti-TMEM154 antibothes for use as therapeutics and diagNOstic methods wherein the disease or condition is associated with KRTCAP3, FAM26F, MGC52498, FAM70A or TMEM154 antigen.
