TAAR1
TAAR1
TAAR1 (pronounced "T-A-A-R-1", /tiː eɪ eɪ ɑːr wʌn/), also known as Trace Amine-Associated Receptor 1, is a protein that in humans is encoded by the TAAR1 gene.
Etymology
The term TAAR1 is an acronym derived from "Trace Amine-Associated Receptor 1". The term "trace amine" refers to the group of chemical compounds that are found in the body in trace amounts, and "associated receptor" refers to the protein that these trace amines bind to.
Function
TAAR1 is a high-affinity receptor for amphetamine, methamphetamine, dopamine, and other trace amines. Trace amines are a group of rare endogenous amines that, in concert with their associated receptors, are believed to play a major role in regulation of brain function, especially in the areas of emotion, motivation, and reward.
