Description

Amino Acid Sequence

Glu-Thr-Pro-Asp-Cys-Phe-Trp-Lys-Tyr-Cys-Val [Disulfide Bridge: 5-10]

Application

Urotensin II human was used in agonist and antagonist preparation for calcium mobilization assay.[1] 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.[2]

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.

A neuroendocrine peptide of the CRF family; potent vasoconstrictor.

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.[3]The product is also a selective and potent vasoconstrictor agent as well as an agonist for the orphan receptor GPR14.[4]
