Background: Endothelin-3

Endothelin-1, -2, and -3 are encoded by three separate genes as prepropolypeptides that are cleaved to yield the secreted and inactive big endothelins. Big  
Endothelin-3 is further cleaved by Kell blood group antigen endopeptidases to generate the 21 amino acid (aa) bioactive mature peptide. It interacts primarily with the 7TM receptor EDNRB to induce a variety of effects including bronchoconstriction, arteriolar vasoconstriction, gall bladder contraction, insulin and norepinephrine release, and the maintenance and development of melanocytes and neural crest progenitors. Mature human Endothelin-3 shares 100% aa sequence identity with mouse and rat Endothelin-3.
