The protein encoded by this gene acts as receptor for arginine vasopressin. This receptor belongs to the subfamily of G-protein coupled receptors which includes AVPR1A, V2R and OXT receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. The receptor is primarily located in the anterior pituitary, where it stimulates ACTH release. It is expressed at high levels in ACTH-secreting pituitary adenomas as well as in bronchial carcinoids responsible for the ectopic ACTH syndrome. A spliced antisense transcript of this gene has been reported but its function is not known. [provided by RefSeq, Jul 2008]
GeneCards Summary for AVPR1B Gene
AVPR1B (Arginine Vasopressin Receptor 1B) is a Protein Coding gene. Diseases associated with AVPR1B include Bronchial Neuroendocrine Tumor and Acth-Independent Macronodular Adrenal Hyperplasia. Among its related pathways are Signaling by GPCR and Peptide ligand-binding receptors. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and protein kinase C binding. An important paralog of this gene is OXTR.
UniProtKB/Swiss-Prot for AVPR1B Gene
Receptor for arginine vasopressin. The activity of this receptor is mediated by G proteins which activate a phosphatidyl-inositol-calcium second messenger system.
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).
