Trace amine-associated receptor GudangMovies21 Rebahinxxi LK21
Trace amine-associated receptors (TAARs), sometimes referred to as trace amine receptors (TAs or TARs), are a class of G protein-coupled receptors that were discovered in 2001. TAAR1, the first of six functional human TAARs, has gained considerable interest in academic and proprietary pharmaceutical research due to its role as the endogenous receptor for the trace amines phenethylamine, tyramine, and tryptamine – metabolic derivatives of the amino acids phenylalanine, tyrosine and tryptophan, respectively – ephedrine, as well as the synthetic psychostimulants, amphetamine, methamphetamine and methylenedioxymethamphetamine (MDMA, ecstasy). In 2004, it was shown that mammalian TAAR1 is also a receptor for thyronamines, decarboxylated and deiodinated relatives of thyroid hormones. TAAR2–TAAR9 function as olfactory receptors for volatile amine odorants in vertebrates.
Animal TAAR complement
The following is a list of the TAARs contained in selected animal genomes:
Human – 6 genes (TAAR1, TAAR2, TAAR5, TAAR6, TAAR8, TAAR9) and 3 pseudogenes (TAAR3, TAAR4P, TAAR7P)
Chimpanzee – 3 genes and 6 pseudogenes
Mouse – 15 genes and 1 pseudogene
Rat – 17 genes and 2 pseudogenes
Zebrafish – 112 genes and 4 pseudogenes
Frog – 3 genes and 0 pseudogenes
Medaka – 25 genes and 1 pseudogenes
Stickleback – 25 genes and 1 pseudogenes
Human trace amine-associated receptors
Six human trace amine-associated receptors (hTAARs) – hTAAR1, hTAAR2, hTAAR5, hTAAR6, hTAAR8, and hTAAR9 – have been identified and partially characterized. The table below contains summary information from literature reviews, pharmacology databases, and supplementary primary research articles on the expression profiles, signal transduction mechanisms, ligands, and physiological functions of these receptors.
