RFRP-1 (human)

RFRP-1 (human) is a gonadotropin-inhibitory hormone (GnIH) homolog. RFRP-1 (human) targets human gonadotropin-releasing hormone (GnRH) neurons and gonadotropes and potently inhibits gonadotropin. RFRP-1 (human) is a potent Neuropeptide FF (NPFF) receptor agonist with EC50s of 0.0011 nM and 29 nM for NPFF2 and NPFF1, respectively[1][2][3].
