Agtr1b Gene Summary [Rat]
Predicted to enable angiotensin type I receptor activity. Involved in several processes, including angiotensin-activated signaling pathway; cellular response to dexamethasone stimulus; and positive regulation of branching involved in ureteric bud morphogenesis. Predicted to be active in plasma membrane. Biomarker of hypertension and renovascular hypertension. 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]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Agtr1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
