NCIt definition : Endothelin-3 (238 aa, 26 kDa) is encoded by the human EDN3 gene. This protein is
involved in vasoconstriction.;
NCIt note : Endothelin-3 is proteolytically processed N-terminally by prohormone convertases and
C-terminally by Kell blood group glycoprotein to release the biologically active form
of endothelin-3, which is composed of amino acids 97-117 of the proprotein and is
a ligand for endothelin B receptor (EDNRB).;
