Hydroxycarboxylic acid receptor 3

Hydroxycarboxylic acid receptor 3 (HCA₃), also known as niacin receptor 2 (NIACR2) and GPR109B,[3] is a protein which in humans is encoded by the HCAR3 gene.[4][5] HCA₃, like the other hydroxycarboxylic acid receptors HCA₁ and HCA₂, is a G_i/o-coupled G protein-coupled receptor (GPCR).[6][7] The primary endogenous agonists of HCA₃ are 3-hydroxyoctanoic acid and kynurenic acid.[6][7][8] HCA₃ is also a low-affinity biomolecular target for niacin (aka nicotinic acid).[9]
