Atxn7 Gene Summary [Mouse]
Enables chromatin binding activity. Acts upstream of or within negative regulation of insulin-like growth factor receptor signaling pathway; negative regulation of phosphorylation; and positive regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; peripheral nervous system; and retina. Used to study spinocerebellar ataxia type 7. Human ortholog(s) of this gene implicated in spinocerebellar ataxia type 7. Orthologous to human ATXN7 (ataxin 7).

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 Atxn7 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
