Human Big ET-1 comprises residues 53-90 of the endothelin precursor (preproendothelin). Compared to the mature endothelin-1 (hET-1), the peptide show less vasoconstrictor activity in vitro, but similar pressor effects in vivo. Former CAS-number 121014-53-7.
Endothelin-1 is one of the there isoforms of endothelin (identified as ET-1, -2, -3) with varying regions of expression and binding to at least four known endothelin receptors, ETA, ETB1, ETB2 and ETC.
Endothelin 1 (swine, human), a synthetic peptide mirroring the sequence of both human and swine Endothelin 1, functions as a robust endogenous vasoconstrictor by interacting with two receptor types, ETA and ETB.
The big endothelins comprise residues 53-90 (human big ET-1) and 53-91 (porcine big ET-1) of the endothelin precursor (preproendothelin). Compared to the mature endothelin-1 (ET-1), both peptides show less vasoconstrictor activity in vitro, but similar pressor effects in vivo. Former CAS-number 121014-54-8.
ENDOTHELIN-1 (ET-1), the principal peptide of the endothelin family, has been shown to have a variety of biological activities in both vascular and nonvascular tissues. The C-terminal fragment, which is a highly conserved sequence in the peptides of t
