生物活性:
RFRP-3 (Neuropeptide VF(124-131))(human), a human GnIH peptide homolog, is a potent inhibitor of gonadotropin secretion by inhibiting Ca2+?mobilization. RFRP-3(human) is a NPFF1?receptor agonist, it inhibits forskolin-induced production of cAMP with an IC50 of 0.7 nM.
体外研究:
RFRP-3 efficiently inhibits forskolin-induced production of cAMP with an IC50 of 0.7 nM.Scatchard-plot analysis shows that 125I-labelled hRFRP-3 has a single class of high-affinity binding sites for the membrane fractions of CHO cells expressing rat OT7T022, the Kd value and the Bmax values are 0.19 nM and 1.3 pM, respectively.RFRP-3 specifically stimulate cells transfected with a new orphan 7TMR, OT7T022, it binds to OT7T022 as a specific ligand with high affinity (Kd= 0.19 nM).RFRP-3 (10-8?to 10-14M) has no effect on LH and FSH levels alone, but when it combines with GnRH, LH and FSH secretion is significantly reduced by the combination.
