GPR3

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]

gollark: We're using humor differential generators? I thought it used humor-contrahumor annihilation.
gollark: The orbital fusion tugship thingy™ is actually departing, so there soon won't be any vessels around for megameters to do drone strikes.
gollark: Electric charge.
gollark: It also probably won't horribly overheat much.
gollark: The osmarks.tk™ solar-orbital broadcast station beams osmarks.tk™ and also 45000Ec/s around the system, and it can serve 4 million requests per second with no* latency!
