Agtr2 Gene Summary [Rat]
Enables angiotensin type II receptor activity. Involved in several processes, including cellular response to dexamethasone stimulus; positive regulation of branching involved in ureteric bud morphogenesis; and regulation of secretion. Located in perinuclear region of cytoplasm. Used to study chronic kidney disease; congenital diaphragmatic hernia; glomerulonephritis (multiple); hypertension (multiple); and meconium aspiration syndrome. Biomarker of several diseases, including asthma; congestive heart failure; glomerulosclerosis (multiple); hypertension; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in IgA glomerulonephritis; end stage renal disease; hypoglycemia; intellectual disability; and vesicoureteral reflux. Orthologous to human AGTR2 (angiotensin II receptor type 2). [provided by Alliance of Genome Resources, Jul 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 Agtr2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
