1 . (canceled)
2 . A method of inhibiting growth of a cell which expresses a 158P1D7 protein, comprising:
providing to the cell an antibody or antigen binding fragment thereof that specifically binds to the 158P1D7 protein, which comprises the amino acid sequence of SEQ ID NO: 3, wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 25-45 or 274-285 of SEQ ID NO: 3, and wherein the cell expressing the protein is a bladder cell, whereby growth of the cell that expresses the protein is inhibited.
3 . The method of claim 2 , wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 25-45 of SEQ ID NO: 3.
4 . The method of claim 2 , wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 274-285 of SEQ ID NO: 3.
5 . The method of claim 2 , wherein the cell is a cancer cell.
6 . The method of claim 2 , wherein the antibody fragment is selected from the group consisting of an Fab, F(ab′)2, Fv and sFv.
7 . The method of claim 2 , wherein the antibody or fragment thereof is labeled with an agent.
8 . The method of claim 7 , wherein the agent is a diagnostic agent or a cytotoxic agent.
9 . The method of claim 8 , wherein the cytotoxic agent is selected from the group consisting of radioactive isotopes, chemotherapeutic agents and toxins.
10 . The method of claim 9 , wherein the radioactive isotope is selected from the group consisting of 211 At, 131 I, 125 I, 90 Y, 186 Re, 188 Re, 153 Sm, 212 Bi, 32 P and radioactive isotopes of Lu.
11 . The method of claim 9 , wherein the chemotherapeutic agent is selected from the group consisting of taxol, actinomycin, mitomycin, etoposide, teniposide, vincristine, vinblastine, colchicine, gelonin, and calicheamicin.
12 . The method of claim 9 , wherein the toxin is selected from the group consisting of diphtheria toxin, enomycin, phenomycin, Pseudomonas exotoxin (PE) A, PE40, abrin, abrin A chain, mitogellin, modeccin A chain, and alpha-sarcin.
13 . A method of inhibiting growth of a cancer cell which expresses a 158P1D7 protein, comprising:
providing to the cell an antibody or antigen binding fragment thereof that specifically binds to the 158P1D7 protein, which comprises the amino acid sequence of SEQ ID NO: 3, wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 25-45 or 274-285 of SEQ ID NO: 3, and wherein the cell expressing the protein is a bladder cancer cell, whereby growth of the cancer cell that expresses the protein is inhibited.
14 . The method of claim 13 , wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 25-45 of SEQ ID NO: 3.
15 . The method of claim 13 , wherein the antibody or antigen binding fragment thereof specifically binds to the protein within amino acid residues 274-285 of SEQ ID NO: 3.
16 . The method of claim 13 , wherein the antibody fragment is selected from the group consisting of an Fab, F(ab′)2, Fv and sFv.
17 . The method of claim 13 , wherein the antibody or fragment thereof is labeled with a diagnostic agent or a cytotoxic agent.
18 . The method of claim 17 , wherein the cytotoxic agent is selected from the group consisting of radioactive isotopes, chemotherapeutic agents and toxins.
19 . The method of claim 18 , wherein the radioactive isotope is selected from the group consisting of 211 At, 131 I, 125 I, 90 Y, 186 Re, 188 Re, 153 Sm, 212 Bi, 32 P and radioactive isotopes of Lu.
20 . The method of claim 18 , wherein the chemotherapeutic agent is selected from the group consisting of taxol, actinomycin, mitomycin, etoposide, teniposide, vincristine, vinblastine, colchicine, gelonin, and calicheamicin.
21 . The method of claim 18 , wherein the toxin is selected from the group consisting of diphtheria toxin, enomycin, phenomycin, Pseudomonas exotoxin (PE) A, PE40, abrin, abrin A chain, mitogellin, modeccin A chain, and alpha-sarcin.
