Big Endothelin-3 (Human, 1-41 Amide) Acetate

CAS: 133551-97-0

Big Endothelin-3 (Human, 1-41 Amide) is a precursor molecule of the Endothelin-3 (ET-3) peptide, that belongs to the large family of endothelin peptides which activate the G-protein coupled receptors ETA and ETB. However ET-3 has lower affinity for the ETA receptors compared to Endothelin-1 (ET-1) and Endothelin-2 (ET-2), whereas all three endothelins have similar affinity for ETB receptors. As ETB receptors make up around 90% of the endothelin receptors found in the cerebral cortex in humans, ET-3 can be nicknamed the ‘brain endothelin’. Also through ET-3’s activation of ETB receptors, ET-3 is involved in the development of the enteric nervous system which controls within the gut, blood flow, secretion and intestinal motility. This product has disulfide bonds between Cys1-Cys15 and Cys3-Cys11.

Big Endothelin-3 (1-41) amide (human) trifluoroacetate salt

CAS: 133551-97-0

Big endothelin-3 is a peptide that is a potent inhibitor of the endothelin receptor. It has been shown to inhibit the binding of endothelin to its receptors and antagonize the effects of endothelin on cells. Big endothelin-3 is a research tool for studying protein interactions, activators, and ligands. This product is the ammonium acetate salt form.
