Background: HM74A/PUMA-G/GPR109A

HM74A/GPR109A (also known as PUMA-G in mouse) is a 50-55 kDa 7-transmembrane protein member of a small subfamily within the GPCR #1 family. It is expressed on or in a wide variety of cells, including microglia, neutrophils, islet beta -cells, macrophages, adipocytes, retinal pigment epithelium and keratinocytes. Although HM74A is noted for its ability to bind niacin, it natural ligand is beta -hydroxybutyrate. Thus it may naturally act as a negative regulator of fatty acid release by fat, which is converted to ketone bodies by the liver, and which feedback on adipocytes. Full-length human HM74A shares 95% amino acid (aa) sequence identity with human HM74 and 81% aa sequence identity with mouse HM74A.
