This gene encodes a precursor protein consisting of arginine vasopressin and two associated proteins, neurophysin 2 and a glycopeptide, copeptin. Arginine vasopressin is a posterior pituitary hormone which is synthesized in the supraoptic nucleus and paraventricular nucleus of the hypothalamus. Along with its carrier protein, neurophysin 2, it is packaged into neurosecretory vesicles and transported axonally to the nerve endings in the neurohypophysis where it is either stored or secreted into the bloodstream. The precursor is thought to be activated while it is being transported along the axon to the posterior pituitary. Arginine vasopressin acts as a growth factor by enhancing pH regulation through acid-base transport systems. It has a direct antidiuretic action on the kidney, and also causes vasoconstriction of the peripheral vessels. This hormone can contract smooth muscle during parturition and lactation. It is also involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of water excretion and cardiovascular functions. Mutations in this gene cause autosomal dominant neurohypophyseal diabetes insipidus (ADNDI). [provided by RefSeq, Mar 2010]
GeneCards Summary for AVP Gene
AVP (Arginine Vasopressin) is a Protein Coding gene. Diseases associated with AVP include diabetes insipidus, neurohypophyseal and hereditary central diabetes insipidus. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include receptor binding and protein kinase activity. An important paralog of this gene is OXT.

Vasopressin receptors are a group of G-protein-coupled receptors that mediate vasoconstriction, antidiuresis and ACTH release. They are currently divided into three subtypes, V1A, V1B and V2 and are closely related to oxytocin receptors (OT). V1A is coupled to Gq/11 proteins and is found at high density on smooth muscle cells. It is involved in regulation of blood pressure through arterial vasoconstriction and has been found to stimulate VEGF secretion. V1B is located in the hypothalamus, where it controls ACTH secretion, and in the pancreas, where it is involved in insulin release. V2 is coupled to Gs proteins and is found exclusively on the basolateral membrane of collecting duct cells in the kidney, where it regulates water excretion.
