Kisspeptin, neuropeptide FF, prolactin-releasing peptide and QRFP receptors

Overview « Hide

Kisspeptin (nomenclature agreed by NC-IUPHAR committee on kisspeptin receptors, Kirby et al., 2010 [12]), neuropeptide FF (NPFF), prolactin-releasing peptide (PrP) and QRFP receptors (provisional nomenclature) respond to endogenous peptides with an arginine-phenylalanine-amide (RFamide) motif. kisspeptin-54 (KP54, originally named metastin), kisspeptin-13 (KP13) and kisspeptin-10 (KP10) are biologically-active peptides cleaved from the KISS1 gene product (ENSG00000170498), while a single propeptide precursor (ENSG00000139574) generates the octapeptides NPFF (FLFQPQRF-NH2, neuropeptide FF or F-8-F-amide) and NPSF (SLAAPQRF-NH2, neuropeptide SF) and the octadecapeptide NPAF (AGEGLSSPFWSLAAPQRF-NH2, neuropeptide AF or A-18-F-amide). NPFF and NPAF were originally isolated from bovine brain [30]. The precursor (ENSG00000071677) for PrRP generates 31 and 20-amino-acid versions. QRFP (named after a pyroglutamylated arginine-phenylalanine-amide peptide) is a 43 amino acid peptide derived from ENSG00000188710 and is also known as P518 or 26RFa. RFRP is an RF amide-related peptide [10] derived from a FMRFamide-related peptide precursor (ENSG00000105954), which is cleaved to generate neuropeptide NPSF, neuropeptide RFRP-1, neuropeptide RFRP-2 and neuropeptide RFRP-3 (neuropeptide NPVF).
