Atn1 Gene Summary [Mouse]
Enables transcription coactivator activity and transcription corepressor activity. Involved in cell migration and maintenance of cell polarity. Acts upstream of or within several processes, including determination of adult lifespan; male gonad development; and negative regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and integumental system. Human ortholog(s) of this gene implicated in dentatorubral-pallidoluysian atrophy and schizophrenia. Orthologous to human ATN1 (atrophin 1). [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 Atn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
