Receptor for 3-OH-octanoid acid mediates a negative feedback regulation of adipocyte lipolysis to counteract prolipolytic influences under conditions of physiological or pathological increases in beta-oxidation rates. Acts as a low affinity receptor for nicotinic acid. This pharmacological effect requires nicotinic acid doses that are much higher than those provided by a normal diet.,GPR109B,HCA3,HM74,PUMAG,Puma-g,HCAR3,G protein signaling,G protein signaling_G-Protein-Coupled Receptors(GPCR),Signal Transduction,HCAR3
