Ar Gene Summary [Rat]
Enables several functions, including androgen binding activity; nuclear androgen receptor binding activity; and nuclear receptor activity. Involved in several processes, including androgen receptor signaling pathway; cellular response to follicle-stimulating hormone stimulus; and regulation of DNA-templated transcription. Located in several cellular components, including axon; dendrite; and nuclear matrix. Used to study hypertension; osteoporosis; prostate adenocarcinoma; prostate cancer; and prostatic hypertrophy. Biomarker of acute kidney failure; androgen insensitivity syndrome; and metabolic dysfunction and alcohol associated liver disease. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; attention deficit hyperactivity disorder; disorder of sexual development (multiple); reproductive organ cancer (multiple); and spinal muscular atrophy (multiple). Orthologous to human AR (androgen receptor). [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 Ar often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
