Screening assay using G-protein coupled receptor protein OT7T175

A method for screening a compound or a salt thereof that alters the binding between a ligand and a protein, said method comprises:

• contacting a protein with a ligand in the presence of a test compound, and
• comparing the binding between said ligand and said protein to a control sample lacking the test compound and selecting the compound that alters said binding as compared to the control sample,
• wherein said protein is selected from the group consisting of:
• (i) the protein comprising the amino acid sequence of SEQ ID NO:
• 5;
• (ii) the protein encoded by the nucleic acid sequence of SEQ ID NO:
• 6;
• and
• (iii) the protein encoded by the nucleic acid sequence at least 95% homologous to SEQ ID NO:
• 6.
