Application

Urotensin II human was used in agonist and antagonist preparation for calcium mobilization assay. The product can also be used as a test compound for studying the impact of dihydropyridine calcium antagonist amlodipine in human internal mammary artery and clinical implications.

Biochem/physiol Actions

A neuroendocrine peptide of the CRF family that was originally isolated from fish brain but is also found in mammalian brain and spinal motor neurons. It is a potent vasoconstrictor. It may be a mediator of stress-induced anorexia.
Human urotensin II is a vasoactive neuropeptide that belongs to CRF family and stimulates arterial smooth muscle contraction, actin stress fiber formation and proliferation via small GTPase RhoA and there downstream effector Rho-kinase activation.The product is also a selective and potent vasoconstrictor agent as well as an agonist for the orphan receptor GPR14.

Graft spasm remains challenging in CABG (coronary artery bypass grafting) surgery. We investigated the inhibitory effect of a dihydropyridine calcium antagonist amlodipine on the vasoconstriction mediated by potassium chloride (KCl), human urotensin-II (hU-II), and U46619 in human internal mammary artery

Urotensin-II (U-II) is a vasoactive 'somatostatin-like' cyclic peptide which was originally isolated from fish spinal cords, and which has recently been cloned from man. Here we describe the identification of an orphan human G-protein-coupled receptor homologous to rat GPR14 and
