Prolactin-Releasing Peptide (1-31) (human)

Prolactin releasing peptide (PrRP) is a 31-amino acid neuropeptide involved in regulating food intake. It is found in the hypothalamus, medulla, and pituitary in rats. PrRP is an agonist of the G-protein coupled receptors GPR10/hGR3 and neuropeptide FF receptor (hNPFF2, Kis = 1 and 19 nM, respectively). It stimulates calcium mobilization in HEK293 cells expressing GPR10 (EC50 = 1.5 nM) and radiolabeled GTPgammaS binding to membrane homogenates from CHO cells transfected with hNPFF2 (EC50 = 240 nM). PrRP (100 nM) increases the release of gonadotropin-releasing hormone (GnRH, Cay-24762), vasoactive intestinal peptide (VIP, Cay-24996), and galanin (Cay-24456) from rat medial basal hypothalamic explants. It increases plasma levels of luteinizing hormone, follicle stimulating hormone, and testosterone in male rats when administered at an intracerebroventricular dose of 5 nmol. PrRP reduces food intake in fasted rats to 58.4, 53.4, and 55.4% of control levels when administered at doses of 1, 5, and 10 nmol, respectively.Formal Name: L-seryl-L-arginyl-L-threonyl-L-histidyl-L-arginyl-L-histidyl-L-seryl-L-methionyl-L-alpha-glutamyl-L-isoleucyl-L-arginyl-L-threonyl-L-prolyl-L-alpha-aspartyl-L-isoleucyl-L-asparaginyl-L-prolyl-L-alanyl-L-tryptophyl-L-tyrosyl-L-alanyl-L-seryl-L-arginylglycyl-L-isoleucyl-L-arginyl-L-prolyl-L-valylglycyl-L-arginyl-L-phenylalaninamide.
