Bach2 Gene Summary [Mouse]
Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in import into nucleus and negative regulation of transcription by RNA polymerase II. Acts upstream of or within regulation of DNA-templated transcription. Located in nucleus. Is expressed in several structures, including ganglia; limb bud; reproductive system; telencephalon; and urinary system. Human ortholog(s) of this gene implicated in immunodeficiency 60. Orthologous to human BACH2 (BTB domain and CNC homolog 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 mouse Bach2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
