Urocortin III, mouse TFA is a corticotropin-releasing factor (CRF)-related peptide. Urocortin III preferentially binds and activates CRF-R2[1]. Urocortin III (Ucn3) is a known component of the behavioral stress response system. Urocortin III and CRF-R2 in the medial amygdala regulate complex social dynamics[2].
