Application

Urocortin III human can be used as a test compound for studying the impacts of melanocortin agonist on in vitro α-subunit secretion.

Biochem/physiol Actions

Urocortin III belongs to corticotropin-releasing hormone family with high affinity for the type 2 corticotropin-releasing factor (CRFR2) receptor. It stimulates insulin and glucagon secretion.Urocortin III also possesses cardioprotective property and has minimal impact on the hypothalamic stress axis. It is, therefore, utilized for treating ischemic heart disease.
Selective ligand with high affinity for CRF2 Receptors

Corticotropin-releasing factor (CRF) receptor type 2beta (CRFR2beta) is expressed in the heart. Urocortin (Ucn)-I activation of CRFR2beta is cardioprotective against ischemic reperfusion (I/R) injury by stimulation of the ERKs1/2 p42, 44. However, by binding CRF receptor type 1, Ucn-I can
