This gene encodes a member of the vasopressin/oxytocin family and preproprotein that is proteolytically processed to generate multiple protein products. These products include the neuropeptide hormone arginine vasopressin, and two other peptides, neurophysin 2 and copeptin. Arginine vasopressin is a posterior pituitary hormone that 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). This gene is present in a gene cluster with the related gene oxytocin on chromosome 20.

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 Phospholipase D signaling pathway and Vasopressin-regulated water reabsorption. GO annotations related to this gene include protein kinase activity and signal transducer activity. An important paralog of this gene is OXT.
UniProtKB/Swiss-Prot for AVP Gene
Neurophysin 2 specifically binds vasopressin.
Vasopressin has a direct antidiuretic action on the kidney, it also causes vasoconstriction of the peripheral vessels.
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).
