Summary: Predicted to enable angiotensin receptor activity; bradykinin receptor binding activity; and protein heterodimerization activity. Involved in regulation of blood pressure. Acts upstream of or within several processes, including blood vessel development; drinking behavior; and regulation of systemic arterial blood pressure by circulatory renin-angiotensin. Predicted to be active in plasma membrane. Is expressed in several structures, including adrenal gland; genitourinary system; heart; liver; and lung. Human ortholog(s) of this gene implicated in several diseases, including COVID-19; artery disease (multiple); chronic kidney disease; neurodegenerative disease (multiple); and sarcoidosis. Orthologous to human AGTR1 (angiotensin II receptor type 1). [provided by Alliance of Genome Resources, Apr 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
