Recombinant Human Trace amine-associated receptor 1 (TAAR1), Truncated

Uniprot Id

Q96RJ0

Target Species

Human

Target Name

TAAR1

Target Full Name

Trace amine-associated receptor 1

Target Function

Receptor for trace amines, including beta-phenylethylamine (b-PEA), p-tyramine (p-TYR), octopamine and tryptamine, with highest affinity for b-PEA and p-TYR. Unresponsive to classical biogenic amines, such as epinephrine and histamine and only partially activated by dopamine and serotonin. Trace amines are biogenic amines present in very low levels in mammalian tissues. Although some trace amines have clearly defined roles as neurotransmitters in invertebrates, the extent to which they function as true neurotransmitters in vertebrates has remained speculative. Trace amines are likely to be involved in a variety of physiological functions that have yet to be fully understood. The signal transduced by this receptor is mediated by the G(s)-class of G-proteins which activate adenylate cyclase

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

G-protein coupled receptor 1 family

Target Tissue Specificity

Detected in low levels in discrete regions within the central nervous system and in several peripheral tissues. Moderately expressed in stomach. Low levels in amygdala, kidney, and lung, and small intestine. Trace amounts in cerebellum, dorsal root gangli

Target Synonyms

TAAR1; TA1; TAR1; TRAR1; Trace amine-associated receptor 1; TaR-1; Trace amine receptor 1

Target Background

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.
