Trace amine-associated receptor 2 (TAAR2), formerly known as G protein-coupled receptor 58 (GPR58), is a protein that in humans is encoded by the TAAR2 gene.[5][6][7][8] TAAR2 is coexpressed with G_α proteins;[8] however, as of February 2017, its signal transduction mechanisms have not been determined.[8]

Human TAAR2 (hTAAR2) is expressed in the cerebellum, olfactory sensory neurons in the olfactory epithelium, and leukocytes (i.e., white blood cells), among other tissues.[9][10] hTAAR1 and hTAAR2 are both required for white blood cell activation by trace amines in granulocytes.[11]

A single nucleotide polymorphism nonsense mutation of the TAAR2 gene is associated with schizophrenia.[8][9] TAAR2 is a probable pseudogene in 10–15% of Asians as a result of a polymorphism that produces a premature stop codon at amino acid 168.[8]

3‐iodo‐thyronamine(T1AM) was identified as a nonselective ligand for TAAR2.[10]
