Background:

Urocortin, human, a 40-aa neuropeptide, acts as a selective agonist of endogenous CRF2 receptor, with Kis of 0.4, 0.3, and 0.5 nM for hCRF1, rCRF2α and mCRF2β, respectively.

Urocortin, human is a selective agonist of CRF2 receptor, with Kis of 0.4, 0.3, and 0.5 nM for human CRF1, rat CRF2α and mouse CRF2β receptors in cell assay, respectively[1].

Urocortin (0.01 to 10 μg) decreases food intake in both food-deprived and non-deprived rats and such a effect also observed in mice after 1 μg of Urocortin i.c.v. administration. Urocortin has the potential of inducing anxiogenic behavior[2].
