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 anti-depressant- and anxiety (anxiolytic)-like behaviors in rats[8].

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