Enables endothelin receptor activity. Involved in several processes, including cellular response to mechanical stimulus; glomerular filtration; and positive regulation of cytosolic calcium ion concentration. Located in T-tubule and nuclear membrane. Colocalizes with membrane raft. Used to study hypertension; myocardial infarction; portal hypertension; pulmonary emphysema; and pulmonary hypertension. Biomarker of several diseases, including hyperhomocysteinemia; impotence; obstructive sleep apnea; renal fibrosis; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in hypertension (multiple); lung disease; mandibulofacial dysostosis with alopecia; migraine; and obstructive sleep apnea. Orthologous to human EDNRA (endothelin receptor type A). [provided by Alliance of Genome Resources, Apr 2022]
