Figure. Concentration-dependent activation of EDNRA by ET‐1

Reporter cells were transfected with either the expression plasmid for human endothelin receptor type A (EDNRA) or the mock plasmid and treated with various concentrations of ET‐1. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 5.5 nM.

Endothelin receptors

Endothelin receptors are activated by the endogenous 21 amino-acid peptides endothelins 1-3 (endothelin-1, endothelin-2 and endothelin-3).
