Arginine vasopressin receptor 1A

Arginine vasopressin receptor 1A (AVPR1A) is a protein that acts as receptor for arginine vasopressin. AVPR1A belongs to the subfamily of G-protein coupled receptors.

Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system.

The activity / genetic variants of the AVPR1 gene might be related to generosity and altruistic behavior.
