Neurohypophysial hormone arginine vasopressin (AVP) regulates body fluid homeostasis, causes vasoconstriction, and releases adrenocorticotropic hormone, among other things. Three subtypes of vasopressin receptors—designated V1a, V1b (or V3), and V2—mediate these physiological effects. They are all members of the large family of G-protein-coupled receptors that resemble rhodopsin.
The V1a receptor stimulates hepatic glycogenolysis, platelet aggregation, coagulation factor release, and cell contraction and proliferation. It is expressed in both neuronal and non-neuronal tissues, including the heart. The pituitary gland is the primary site of the V1b receptor subtype, which is responsible for stimulating the release of adrenocorticotropic hormone. The G protein alpha-subunit of the Gαq family (αq, q11, q14, α15/16) is the mechanism by which the V1a and V1b AVP receptors activate phospholipase C-β, raising the levels of calcium and IP3 in cells. On the other hand, the V2 receptor subtype is primarily found in the kidney, where it activates adenylyl cyclase and mediates the anti-diuretic effects of AVP via the heterotrimeric G protein Gs.
