The protein encoded by this gene is a G protein-coupled receptor which activates a phosphatidylinositol-calcium second messenger system. Its ligand, endothelin, consists of a family of three potent vasoactive peptides: ET1, ET2, and ET3. Studies suggest that the multigenic disorder, Hirschsprung disease type 2, is due to mutations in the endothelin receptor type B gene. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]
GeneCards Summary for EDNRB Gene
EDNRB (Endothelin Receptor Type B) is a Protein Coding gene. Diseases associated with EDNRB include Waardenburg Syndrome, Type 4A and Hirschsprung Disease 2. Among its related pathways are Peptide ligand-binding receptors and Interleukin-3, 5 and GM-CSF signaling. GO annotations related to this gene include G-protein coupled receptor activity and type 1 angiotensin receptor binding. An important paralog of this gene is NMBR.
UniProtKB/Swiss-Prot for EDNRB Gene
Non-specific receptor for endothelin 1, 2, and 3. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.
The endothelinB receptor (ETB receptor) is a member of the endothelin receptor group of G-protein-coupled receptors that also includes ETA. They are located primarily in vascular endothelial cells where they play a role in vasoconstriction, vasodilation and cell proliferation.
