Trace amine-associated receptor 5 is a protein that in humans is encoded by the TAAR5 gene.[5][6][7] In vertebrates, TAAR5 is expressed in the olfactory epithelium.[8]

Human TAAR5 (hTAAR5) is a functional trace amine-associated receptor which acts as an olfactory receptor for tertiary amines.[8][9] Trimethylamine and N,N-dimethylethylamine are full agonists of hTAAR5.[9][10][11] The amber-woody fragrance timberol antagonizes this activity of trimethylamine.[12] 3-Iodothyronamine is an inverse agonist of hTAAR5.[13][14]

We show that [human TAAR5] responds to the tertiary amine N,N-dimethylethylamine and to a lesser extent to trimethylamine, a structurally related agonist for mouse and rat TAAR5 (Liberles and Buck, 2006; Staubert et al., 2010; Ferrero et al., 2012).

While mice produce gender-specific amounts of urinary TMA levels and were attracted by TMA, this odor is repellent to rats and aversive to humans [19], indicating that there must be species-specific functions. ... Furthermore, a homozygous knockout of murine TAAR5 abolished the attraction behavior to TMA [19]. Thus, it is concluded that TAAR5 itself is sufficient to mediate a behavioral response at least in mice. ... Whether the TAAR5 activation by TMA elicits specific behavioral output like avoidance behavior in humans still needs to be examined.
