Bioactivity
Urocortin III (human) is a corticotropin-releasing factor (CRF) -related peptide that primarily interacts with and activates the CRF receptor type 2 (CRF-R2), showing a specific distribution in the central nervous system and periphery. It selectively binds to type 2 CRF receptors with dissociation constants (Ki values) of 13.5 nM for mouse CRF2β, 21.7 nM for rat CRF2α, and >100 nM for human CRF1, indicating a strong preference for CRF-R2 over CRF1. Additionally, Urocortin III (human) plays a crucial role in the somatostatin-dependent negative feedback mechanism regulating the secretion of Insulin (human) .
