Aptx Gene Summary [Rat]

Predicted to enable several functions, including DNA binding activity; double-stranded RNA binding activity; and hydrolase activity, acting on ester bonds. Predicted to be involved in regulation of protein stability and single strand break repair. Predicted to be located in chromatin; nucleolus; and nucleoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in ataxia with oculomotor apraxia type 1 and olivopontocerebellar atrophy. Orthologous to human APTX (aprataxin).

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