Trace amine-associated receptor

Trace amine-associated receptor (pronounced: /treɪs ˈeɪmiːn əˈsoʊʃieɪtɪd rɪˈsɛptər/), often abbreviated as TAAR, is a class of G protein-coupled receptors that was discovered in the early 2000s. The term "trace amine" refers to the fact that these receptors are activated by compounds present in the body at very low ('trace') concentrations.

Etymology

The term "trace amine-associated receptor" is derived from the fact that these receptors are activated by trace amines, which are compounds present in the body at very low ('trace') concentrations. The term "receptor" refers to the fact that these proteins receive signals from outside the cell and initiate a response inside the cell.

Function

Trace amine-associated receptors are found in various parts of the body, including the brain, heart, and lungs. They are involved in a variety of physiological processes, including regulation of neurotransmitter release, cardiovascular function, and respiratory function.

Related Terms

G protein-coupled receptor: A large family of receptors that trace amine-associated receptors belong to.
Neurotransmitter: Chemicals that transmit signals from a neuron to a target cell across a synapse.
Cardiovascular: Pertaining to the heart and blood vessels.
Respiratory: Pertaining to the process of respiration, or breathing.
