RF(Arg-Phe)amide family 26 amino acid peptide, also known as P518, is a human protein.{{cite web | title = Entrez Gene: P518 RF(Arg-Phe)amide family 26 amino acid peptide| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=347148}}

The 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.{{cite journal | vauthors = Jiang Y, Luo L, Gustafson EL, Yadav D, Laverty M, Murgolo N, Vassileva G, Zeng M, Laz TM, Behan J, Qiu P, Wang L, Wang S, Bayne M, Greene J, Monsma F, Zhang FL | title = Identification and characterization of a novel RF-amide peptide ligand for orphan G-protein-coupled receptor SP9155 | journal = J. Biol.

Intravenous administration QRFP caused release of aldosterone, suggesting that QRFP and GPR103 regulate adrenal function.{{cite journal | vauthors = Fukusumi S, Yoshida H, Fujii R, Maruyama M, Komatsu H, Habata Y, Shintani Y, Hinuma S, Fujino M | title = A new peptidic ligand and its receptor regulating adrenal function in rats | journal = J.
