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 GTPγS binding to membrane homogenates from CHO cells transfected with hNPFF2 (EC50 = 240 nM). PrRP (100 nM) increases the release of gonadotropin-releasing hormone , vasoactive intestinal peptide-, and galanin 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.
