Trace amine-associated receptor 5 is a protein that in humans is encoded by the TAAR5 gene.[3][4][5] In vertebrates, TAAR5 is expressed in the olfactory epithelium.[6]

Human TAAR5 (hTAAR5) is a functional trace amine-associated receptor which acts as an olfactory receptor for tertiary amines.[6][7] Trimethylamine (TMA) and N,N-dimethylethylamine are full agonists of hTAAR5.[7][8][9] The amber-woody fragrance timberol antagonizes this activity of TMA.[10] 3-Iodothyronamine acts as an inverse agonist at hTAAR5.[11]
