Aptx - aprataxin

Enables DNA 5'-adenosine monophosphate hydrolase activity. Involved in single strand break repair. Acts upstream of or within DNA ligation. Predicted to be located in nucleolus and nucleoplasm. Predicted to be active in nucleus. Predicted to colocalize with chromatin. Is expressed in several structures, including brain; cardiovascular system; genitourinary system; gut; and respiratory system. Human ortholog(s) of this gene implicated in ataxia with oculomotor apraxia type 1 and olivopontocerebellar atrophy. Orthologous to human APTX (aprataxin).
