TAAR9: Lysates

TAAR9/TA3 is an Orphan-A GPCR because the ligand has not been identified. TAAR9/TA3 was identified by degenerate PCR because of its similarity to other trace amine receptors. The close proximity on chromosome 6 and high sequence homology to the other trace amine receptors suggest that TAAR9/TA3 is likely to bind a related or unidentified amine. TAAR9/TA3 has been reported to be expressed only in kidney.
