Urocortin II, mouse, is a selective and potent endogenous peptide agonist for the type-2 corticotropin-releasing factor (CRF2) receptor, displaying K_i values of 0.66 nM for CRFR2 and >100 nM for CRFR1, signifying its high specificity. It engages CRF2 receptors through mechanisms dependent on cAMP/PKA and Ca2+/CaMKII. Additionally, Urocortin II, mouse is localized in specific regions of the central nervous system, influencing central neurons that process visceral sensory information and regulate autonomic functions [1] [2] [3].
