Urocortin III (human) (TFA)

Urocortin III (human) TFA is a corticotropin-releasing factor (CRF) -related peptide. Urocortin III (human) TFA preferentially binds and activates CRF-R2 and has a discrete central nervous system and peripheral distribution. Urocortin III (human) TFA potently binds to type 2 CRF receptors, specifically mCRF2β (Ki = 13.5 nM) and rCRF2α (Ki = 21.7 nM), while demonstrating negligible affinity for hCRF1 (Ki >100 nM) . Urocortin III (human) TFA mediates somatostatin-dependent negative feedback control of Insulin (human) (HY-P0035) secretion[1][2].
