GPR103 (G protein-spregnuti receptor 103, piroglutamilisani RF amid peptidni receptor, oreksigenski neuropeptidni QRFP receptor) jeprotein koji je kod čoveka kodiranQRFPRgenom.^[1]^[2]

Funkcija

[uredi |uredi kod]

G protein spregnuti receptori sadrže sedamtransmembranskih domena i prenose ekstracelularne signale putemheterotrimernih G proteina.^[1]

P518, RF-amidni peptid sa 26 aminokiselina, funkcioniše kao ligand visokog afiniteta za GPR103 receptor.iRNK prekursori GPR103 i P518 proteina su visoko izraženi u mozgu.^[3]QRFP peptid sa 43 aminokiselina, što je duži oblik P518 peptida, je neophodan za punuagonističku aktivnosti GPR103 receptora. Intravenozna administracija QRFP peptida uzrokuje oslobađanjealdosterona, iz čega proizilazi da QRFP i GPR103 regulišuadrenalnu funkciju.^[4]
