Arginine vasopressin receptor 1B (AVPR1B, vasopressin 3 receptor) is a protein that acts as receptor for arginine vasopressin. AVPR1B belongs to the subfamily of G-protein coupled receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system.

AVPR1B was initially described as a novel vasopressin receptor located in the anterior pituitary, where it stimulates ACTH release (1), especially in synergism with corticotropin releasing factor. Subsequent studies have shown its presence in the brain as well (2),(3).

Inactivation of the Avpr1b in mice (knockout) produces mice with greatly reduced aggression and a reduced ability to recognize recently investigated mice (4). Interestingly, defensive behavior and predatory behaviors appear to normal in these knockout mice (5). There is evidence that social motivation or awareness is reduced in these mice (6). The AVPR1B antagonist, SSR149415, has been shown to have anti-aggressive actions in hamsters (7) and antidepressant and anxiety (anxiolytic)-like behaviors in rats (8).

Various stress-induced elevations of ACTH are blunted in the Avpr1b knockout mouse (9). AVPR1B is expressed at high levels in ACTH-secreting pituitary adenomas as well as in bronchial carcinoids responsible for the ectopic ACTH syndrome.

The expression of this receptor also has an interesting form of self-regulation. Short peptides ("uORFs") of 10-38 amino acids in length encoded in the 5' "untranlated region" of the the Avpr1b gene provide negative feedback on its expression through inhibition of translation (10).

A single nucleotide polymorphism (SNP) has been associated with susceptiblility to depression in man (11).
