Patent ID: 7625714

Claim:
A method for identifying an odorant receptor ligand, comprising: a) providing i) a cell comprising an odorant receptor, wherein said cell further comprises a first heterologous nucleic acid encoding a polypeptide comprising an amino acid sequence that is at least 80% identical to SEQ ID No. 37, wherein said polypeptide is capable of promoting odorant receptor cell surface localization and odorant receptor functional expression, and a second heterologous nucleic acid encoding a polypeptide comprising an amino acid sequence that is at least 80% identical to SEQ ID No. 38, wherein said polypeptide is capable of promoting odorant receptor cell surface localization and odorant receptor functional expression, ii) at least one test compound; b) exposing said test compound to said cell; and c) detecting the activity of said odorant receptor.
