{{Infobox_gene}}Pyroglutamylated RFamide peptide receptor also known as orexigenic neuropeptide QRFP receptor or G-protein coupled receptor 103 (GPR103) is a protein that in humans is encoded by the QRFPR gene.[1][1]FunctionG protein-coupled receptors (GPCRs, or GPRs) contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.[2]A 26-amino acid RF-amide peptide, P518 functions as a high-affinity ligand of GPR103. Both GPR103 and P518 precursor mRNA exhibited highest expression in brain.[3] The 43-amino acid QRFP peptide, a longer form of the P518 peptide is necessary to exhibit full agonistic activity with GPR103. Intravenous administration QRFP caused release of aldosterone, suggesting that QRFP and GPR103 regulate adrenal function.[4] References1. ^{{cite journal |vauthors=Lee DK, Nguyen T, Lynch KR, Cheng R, Vanti WB, Arkhitko O, Lewis T, Evans JF, George SR, O'Dowd BF | title = Discovery and mapping of ten novel G protein-coupled receptor genes | journal = Gene | volume = 275 | issue = 1 | pages = 83–91 |date=September 2001 | pmid = 11574155 | doi = 10.1016/S0378-1119(01)00651-5 | url = | issn = }}
