Urotensin II (U-II) is a cyclic heptapeptide that functions both as a potent vasoconstrictor and a neurotransmitter/ neuromodulator.
U-II circulates in the plasma as a zymogen, and is activated by the urotensin converting enzyme.
U-II is the endogenous ligand for the G-protein coupled receptor 14 (GPR14), recently renamed the UT receptor.
Changes in the expression of U-II and its receptor have been associated with cardiovascular and renal diseases, including atherosclerosis, myocardial infarction, and diabetic nephropathy.
