FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a G-protein coupled receptor activated by trace amines. The encoded protein responds little or not at all to dopamine, serotonin, epinephrine, or histamine, but responds well to beta-phenylethylamine, p-tyramine, octopamine, and tryptamine. While primarily functioning in neurologic systems, there is evidence that this gene is involved in blood cell and immunologic functions as well. This gene is thought to be intronless.

PHENOTYPE: Mice homozygous for a null mutation display decreased prepulse inhibition and increased sensitivity to amphetamines. Mice homozygous for another knock-out allele exhibit increased sensitivity to MDMA-induced hyperthermia, brain dopamine and serotonin levels, and induced hyperactivity. [provided by MGI curators]
