Function

function

Olfactory receptor activated by several primary trace amines, including isoamylamine. Activated by isoamylamine and cyclohexylamine, but not to the corresponding alcohols, isoamylalcohol and cyclohexanol. This receptor is probably mediated by the G(s)-class of G-proteins which activate adenylate cyclase.

Phenotypes & Variants

Disruption phenotype

Mice lacking Taar2, Taar3, Taar4, Taar5, Taar6, Taar7a, Taar7b, Taar7d, Taar7e, Taar7f, Taar8a, Taar8b, Taar8c and Taar9 show no visible phenotype or behavioral deficits. They however show an absence of aversion to low concentrations of amines such as 2-phenylethylamine, isopentylamine, N-methylpiperidine and cadaverine.
