a) culturing the host cell of claim 14 under conditions for expression of protein; and b) recovering the protein from the host cell culture.
- 16. A protein or a portion thereof produced by the method of claim 15.
- 17. A method for using a protein to screen a plurality of molecules or compounds to identify at least one ligand which specifically binds the protein, the method comprising:
a) combining the protein of claim 16 with the plurality of molecules or compounds under conditions to allow specific binding; and b) detecting specific binding between the protein and a molecule or compound, thereby identifying a ligand which specifically binds the protein.
- 18. The method of claim 17 wherein the plurality of molecules or compounds is selected from agonists, antagonists, antibodies, DNA molecules, small molecule drugs, immunoglobulins, inhibitors, mimetics, peptide nucleic acids, peptides, pharmaceutical agents, proteins, RNA molecules, and ribozymes.
- 19. An antagonist identified by the method of claim 16.
- 20. An isolated antibody which specifically binds to a protein of claim 16.
- 21. The antibody of claim 20, wherein the antibody is selected from a polyclonal antibody, a monoclonal antibody, a chimeric antibody, a recombinant antibody, a humanized antibody, a single chain antibody, a Fab fragment, an F(ab′)2 fragment, an Fv fragment; and an antibody-peptide fusion protein.
- 22. A method of using a protein to prepare and purify a polyclonal antibody comprising:
