Arginine Vasopressin Induced Protein 1 (AVPI1)

Arginine vasopressin-induced protein 1 is a protein encoded by the AVPI1 gene.One of the most important roles of AVP is to regulate the body"""s retention of water; it is released when the body is dehydrated and causes the kidneys to conserve water, thus concentrating the urine, and reducing urine volume. In high concentrations, it also raises blood pressure by inducing moderate vasoconstriction. In addition, it has a variety of neurological effects on the brain, having been found, for example, to influence pair-bonding in voles. The high-density distributions of vasopressin receptor AVPr1a in prairie vole ventral forebrain regions have been shown to facilitate and coordinate reward circuits during partner preference formation, critical for pair bond formation .
