Anti-Vasopressin Receptor V1b (Arg) (AVR-V1b)

Vasopressin (AVP, Arginine-8-Vasopressin), the antidiuretic hormone is cyclic nonapeptide invovled in the homeostasis of body fluid osmolality, blood volume, vascular tone, and blood pressure. Specific actions of AVP include inhibition of diuresis, contraction of smooth muscle, stimulation of liver glycogenesis, and modulation of ACTH release from pituitary. AVP belongs to the family of vasocative and mitogenic peptide invovled in normal and pathological cell growth and differentiation. AVP exerts its action through binding to specific membrane receptors coupled to distinct second messengers. There are 3 types of AVP receptors: V1a, V1b, and V2 subtypes. The V2 receptor stimulates adenyl cyclase and protein Kinase A, V1 activate phospholipase A2.C, and D, resulting into production of IP3 and DAG, the mobilization of intracellular calcium, the influx of extracellular calcium, the activation of protein Kinase C, and protein phosphorylation. The V1a receptors mediate vasoconstriction and hepatic gluconeogenesis platelet aggregation, coagulation factor release. V1a receptors are found in vascular smooth muscle, hepatocytes, blood platelets, lymphocytes and monocyte, type II pneumocytes, adrenal cortex, brain, reproductive organs, retinal epithelium, renal mesangial cells. , Applications:, Suitable for use in Western Blot, Immunohistochemistry and ELISA.
