GeneCards Summary for HCAR2 Gene
HCAR2 (Hydroxycarboxylic Acid Receptor 2) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors and Hydroxycarboxylic acid-binding receptors. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and nicotinic acid receptor activity. An important paralog of this gene is HCAR3.
UniProtKB/Swiss-Prot Summary for HCAR2 Gene
Acts as a high affinity receptor for both nicotinic acid (also known as niacin) and (D)-beta-hydroxybutyrate and mediates increased adiponectin secretion and decreased lipolysis through G(i)-protein-mediated inhibition of adenylyl cyclase. This pharmacological effect requires nicotinic acid doses that are much higher than those provided by a normal diet. Mediates nicotinic acid-induced apoptosis in mature neutrophils. Receptor activation by nicotinic acid results in reduced cAMP levels which may affect activity of cAMP-dependent protein kinase A and phosphorylation of target proteins, leading to neutrophil apoptosis. The rank order of potency for the displacement of nicotinic acid binding is 5-methyl pyrazole-3-carboxylic acid = pyridine-3-acetic acid > acifran > 5-methyl nicotinic acid = acipimox >> nicotinuric acid = nicotinamide.
