Vasopressin receptor

Vasopressin receptors are cell surface receptors "to which vasopressins bind or interact in order to modify the function of the cells. Two types of vasopressin receptor exist, the V1 receptor in the vascular smooth muscle and the V2 receptor in the kidneys. The V1 receptor can be subdivided into V1a and V1b (formerly V3) receptors."[1]

Classification
| Type | Second messenger system | Locations | Actions |
|---|---|---|---|
| AVPR1A | phosphatidylinositol/calcium | liver, kidney, peripheral vasculature, brain | vasoconstriction, gluconeogenesis, platelet aggregation, and release of factor VIII and von Willebrand factor; social recognition[2], circadian tau[3] |
| AVPR1B | phosphatidylinositol/calcium | pituitary gland, brain | adrenocorticotropic hormone secretion in response to stress[4]; social interpretation to olfactory cues[5] |
| AVPR2 | adenylate cyclase/cAMP | apical membrane of the cells lining the collecting ducts of the kidneys (especially the cortical and outer medullary collecting ducts) | insertion of aquaporin-2 (AQP2) channels (water channels). This allows water to be reabsorbed down an osmotic gradient, and so the urine is more concentrated. |
