G-protein coupled receptor 3 is a protein that in humans is encoded by the GPR3 gene.[5][6] The protein encoded by this gene is a member of the G protein-coupled receptor family of transmembrane receptors and is involved in signal transduction.

Function

GPR3 activates adenylate cyclase in the absence of ligand.[7] GPR3 is expressed in mammalian oocytes where it maintains meiotic arrest and is thought to be a communication link between oocytes and the surrounding somatic tissue.[8] It has been proposed that sphingosine 1-phosphate (S1P) and sphingosylphosphorylcholine (SPC) are GPR3 ligands,[9][10] however this result was not confirmed in a β-arrestin recruitment assay.[11]

Mice lacking GPR3 were found to develop late-onset obesity owing to decreased UCP-1 expression in brown adipose tissue and reduced thermogenic capacity.[12]
