External Ids for EDN3 Gene
The protein encoded by this gene is a member of the endothelin family. Endothelins are endothelium-derived vasoactive peptides involved in a variety of biological functions. The active form of this protein is a 21 amino acid peptide processed from the precursor protein. The active peptide is a ligand for endothelin receptor type B (EDNRB). The interaction of this endothelin with EDNRB is essential for development of neural crest-derived cell lineages, such as melanocytes and enteric neurons. Mutations in this gene and EDNRB have been associated with Hirschsprung disease (HSCR) and Waardenburg syndrome (WS), which are congenital disorders involving neural crest-derived cells. Altered expression of this gene is implicated in tumorigenesis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

Endothelins are endothelium-derived vasoconstrictor peptides
The endothelin family consists of highly potent vasoconstrictive peptides. Three endogenous isoforms are known to exist, ET-1, ET-2 and ET-3, and two distinct endothelin receptors have so far been cloned in mammals, classified as ETA and ETB receptors. Endothelin receptors are widely expressed in all tissues, which is consistent with their physiological role as vasoactive peptides. They are also localized to non-vascular structures including epithelial cells, glia and neurons. The principle physiological role of endothelin receptors is the maintenance of vascular tone. They also have co-mitogenic activity, potentiating the effects of other growth factors such as PDGF.
