Endothelin-3 (human, rat) (trifluoroacetate salt)

Endothelin-3 is a peptide vasoconstricter and a ligand of the endothelin (ET) receptors ETA and ETB (Kbs = 1.05 and 1.49, respectively). It induces beta-arrestin recruitment in CHO-K1 cells expressing human ETA and ETB (pD2s = 7.31 and 9.44, respectively). Endothelin-3 increases blood pressure in spontaneously hypertensive and normotensive rats when administered at doses of 310 and 955 pmol/kg, respectively. It also stimulates migration and adhesion of enteric neural crest cells (ENCCs) to the embryonic gut in mice via interaction with ETB. Mutations in the endothelin-3 gene, Edn3, induce distal aganglionosis caused by failed colonization of ENCCs in the hindgut and lack of ENCC migration to the ileo-caecal junction in mice.Formal Name: L-cysteinyl-L-threonyl-L-cysteinyl-L-phenylalanyl-L-threonyl-L-tyrosyl-L-lysyl-L-alpha-aspartyl-L-lysyl-L-alpha-glutamyl-L-cysteinyl-L-valyl-L-tyrosyl-L-tyrosyl-L-cysteinyl-L-histidyl-L-leucyl-L-alpha-aspartyl-L-isoleucyl-L-isoleucyl-L-tryptophan cyclic (1->15),(3->11)-bis(disulfide), 2,2,2-trifluoroacetate.
