Predicted to enable angiotensin type I receptor activity. Involved in several processes, including cellular response to hormone stimulus; positive regulation of branching involved in ureteric bud morphogenesis; and response to estrogen. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Biomarker of hypertension and renovascular hypertension. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; COVID-19; artery disease (multiple); chronic kidney disease; and sarcoidosis. Orthologous to human AGTR1 (angiotensin II receptor type 1). [provided by Alliance of Genome Resources, Apr 2022]
