Esr2 Gene Summary [Rat]
Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; estrogen response element binding activity; and steroid binding activity. Involved in several processes, including brain development; regulation of transcription by RNA polymerase II; and reproductive structure development. Located in mitochondrion; perikaryon; and perinuclear region of cytoplasm. Part of protein-DNA complex. Used to study several diseases, including hypertension (multiple); obesity; peritonitis; prostate carcinoma in situ; and transient cerebral ischemia. Biomarker of asthma; brain ischemia; colitis; cystitis; and osteoporosis. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autoimmune disease (multiple); bone disease (multiple); hypospadias; and neurodegenerative disease (multiple). Orthologous to human ESR2 (estrogen receptor 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 Esr2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
