产品描述

Urotensin I is, 41-aa neuropeptide, acts as an agonist of CRF receptor with pEC50s of 11.46, 9.36 and 9.85 for human CRF1, human CRF2 and rat CRF2α receptors in CHO cells, and Kis of 0.4, 1.8, and 5.7 nM for hCRF1, rCRF2α and mCRF2β receptors, respectively.

Urotensin I is a 41-aa neuropeptide, acts as an agonist of CRF receptor with pEC50s of 11.46, 9.36 and 9.85 for human CRF1, human CRF2 and rat CRF2α receptors in CHO cells[1] and with Kis of 0.4, 1.8, and 5.7 nM for hCRF1, rCRF2α and mCRF2β receptors in cell assay, respectively[2]. Urotensin I exhibits a striking sequence homology with ovine corticotropin-releasing factor and with frog sauvagine, and has potent hypotensive activity and corticotropin-releasing activity[3]. Urotensin I stimulates the release of ACTH from an isolated dispersed goldfish anterior pituitary cell column[4].
