Endothelin-1/EDN1 Protein, Human (GST)

Endothelin-1/EDN1, an endothelium-derived vasoconstrictor peptide, acts as a likely ligand for G-protein coupled receptors EDNRA and EDNRB. Its binding initiates a signaling cascade in glomerular mesangial cells involving PTK2B, BCAR1, BCAR3, and GTPases RAP1 and RHOA. Furthermore, Endothelin-1/EDN1 shows binding affinity for the DEAR/FBXW7-AS1 receptor, underscoring its involvement in diverse cellular signaling and vascular regulation. Endothelin-1/EDN1 Protein, Human (GST) is the recombinant human-derived Endothelin-1/EDN1 protein, expressed by E. coli , with N-GST labeled tag.

Endothelin-1/EDN1, a vasoconstrictor peptide derived from the endothelium, serves as a probable ligand for G-protein coupled receptors EDNRA and EDNRB. Upon binding, it activates a signaling cascade involving PTK2B, BCAR1, BCAR3, and GTPases RAP1 and RHOA in glomerular mesangial cells. Additionally, Endothelin-1/EDN1 exhibits binding affinity for the DEAR/FBXW7-AS1 receptor, contributing to its diverse roles in cellular signaling and vascular regulation.

1.Measured by its binding ability in a functional ELISA. Immobilized EDNRB at 5 μg/mL can bind human EDN1 with a linear range of 37035-185619 ng/mL.
2.Measured by its binding ability in a functional ELISA. Immobilized EDNRB at 0.5 μg/mL can bind human EDN1 with a linear range of 213.5-245.4 μg/ml.
