Summary
TAAR1 (trace amine associated receptor 1, HGNC:17734) is a protein-coding gene on chromosome 6q23.2, encoding Trace amine-associated receptor 1 (Q96RJ0). Intracellular G-protein coupled receptor for trace amines, which recognizes endogenous amine-containing metabolites such as beta-phenylethylamine (beta-PEA), 3-iodothyronamine (T1AM), isoamylamine (IAA), cadaverine (CAD), cyclohexylamine (CHA), p-tyramine (p-TYR), trimethylamine….
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.

Function. Intracellular G-protein coupled receptor for trace amines, which recognizes endogenous amine-containing metabolites such as beta-phenylethylamine (beta-PEA), 3-iodothyronamine (T1AM), isoamylamine (IAA), cadaverine (CAD), cyclohexylamine (CHA), p-tyramine (p-TYR), trimethylamine (TMA), octopamine and tryptamine. Also functions as a receptor for various drugs and psychoactive substances, such as amphetamine and methamphetamine. Unresponsive to classical biogenic amines, such as epinephrine and histamine and only partially activated by dopamine and serotonin. Expressed in both the central and peripheral nervous system: TAAR1 activation regulates the activity of several neurotransmitter signaling pathways by (1) decreasing the basal firing rates of the neurons involved and by (2) lowering the sensitivity of receptors to neurotransmitters. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors. TAAR1 is coupled with different G(i)/G(o)-, G(s)- or G(q)/G(11) classes of G alpha proteins depending on the ligand. CAD-binding is coupled to G(i)/G(o) G alpha proteins and mediates inhibition of adenylate cyclase activity. T1AM- or beta-PEA-binding is coupled to G(s) G alpha proteins and mediates activation of adenylate cyclase activity. CHA- or IAA-binding is coupled to G(q)/G(11) G alpha proteins and activates phospholipase C-beta, releasing diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) second messengers. TMA-binding is coupled with all three G(i)/G(o)-, G(s)- or G(q)/G(11) G alpha protein subtypes. Amphetamine-binding is coupled with G(s)- or G(12)/G(13) G alpha protein subtypes.
Subcellular location. Endomembrane system. Endoplasmic reticulum membrane. Cell membrane.
Tissue specificity. Expressed at low level in both the central and peripheral nervous system. Moderately expressed in stomach. Low levels in amygdala, kidney, and lung, and small intestine. Trace amounts in cerebellum, dorsal root ganglia, hippocampus, hypothalamus, liver, medulla, pancreas, pituitary, pontine reticular formation, prostate, skeletal muscle and spleen.
Activity regulation. Activated by SEP-363856 small molecule: IHCH-7179 acts both as an agonist activator for HTR1A and TAAR1.
Similarity. Belongs to the G-protein coupled receptor 1 family.
