Trace amine-associated receptor 5 (TAAR5)

Olfactory receptor specific for trimethylamine, a trace amine. Additionally triggered at lower level by dimethylethylamine.

Trimethylamine is a bacterial metabolite found in certain animal odors, and to humans it is a repulsive odor associated with bad breath and spoiled food. This receptor is likely mediated by the G(s)-course of G-proteins which activate adenylate cyclase.
