What is "urotensin-ii"

Urotensin-II (U-II) is a peptide ligand that is the strongest known vasoconstrictor. Because of the involvement of the UII system in multiple biological systems such as the cardiovascular, nervous, endocrine, and renal, it represents a promising target for the development of new drugs.

In humans, Urotensin-2 is encoded by the UTS2 gene.
