Urotensin-II (U-II) is a 11 amino acids peptide ligand encoded by the UTS2 gene. It binds to a class of G protein-coupled receptor known as GPR14 or the urotensin receptor. It has been reported that Urotensin-II is involved in the cardiovascular, nervous, endocrine, pulmonary, renal and metabolic systems. Elevated plasma levels of U-II have been shown in numerous diseased conditions, such as hypertension, atherosclerosis and heart failure. U-II and its receptor represent promising targets for the development of new drugs.
