Summary: 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 chromatin; nucleolus; and nucleoplasm. Predicted to be active in nucleus. 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).

What's a GeneRIF?

Interaction with phosphorylated XRCC1 is a requirement for significant APTX recruitment to cellular DNA damage and enzymatic activity in cell extracts.
Title: XRCC1 phosphorylation affects aprataxin recruitment and DNA deadenylation activity.
Study demonstrates a protective role of Aptx in vivo and suggests that its loss results in progressive accumulation of DNA breaks in the nervous system, triggering hallmarks of premature ageing, systemically.
Title: Expression of a pathogenic mutation of SOD1 sensitizes aprataxin-deficient cells and mice to oxidative stress and triggers hallmarks of premature ageing.
aprataxin participates in chromosomal single-strand break repair
Title: Defective DNA ligation during short-patch single-strand break repair in ataxia oculomotor apraxia 1.
neurological disorders associated with APTX mutations may be caused by the gradual accumulation of unrepaired DNA strand breaks resulting from abortive DNA ligation events
Title: The neurodegenerative disease protein aprataxin resolves abortive DNA ligation intermediates.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
