Function DNA-binding protein involved in single-strand DNA break repair, double-strand DNA break repair and base excision repair. Resolves abortive DNA ligation intermediates formed either at base excision sites, or when DNA ligases attempt to repair non-ligatable breaks induced by reactive oxygen species. Catalyzes the release of adenylate groups covalently linked to 5'-phosphate termini, resulting in the production of 5'-phosphate termini that can be efficiently rejoined. Also able to hydrolyze adenosine 5'-monophosphoramidate (AMP-NH(2)) and diadenosine tetraphosphate (AppppA), but with lower catalytic activity.
Subcellular Location Nucleus, nucleoplasm. Nucleus, nucleolus. Upon genotoxic stress, colocalizes with XRCC1 at sites of DNA damage. Colocalizes with MDC1 at sites of DNA double-strand breaks. Interaction with NCL is required for nucleolar localization.; Isoform 12: Cytoplasm.
Involvement in Disease Ataxia-oculomotor apraxia syndrome: An autosomal recessive syndrome characterized by early-onset cerebellar ataxia, oculomotor apraxia, early areflexia and late peripheral neuropathy. The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Widely expressed. In brain, it is expressed in the posterior cortex, cerebellum, hippocampus and olfactory bulb. Isoform 1 is highly expressed in the cerebral cortex and cerebellum, compared to isoform 2.
Subunit Structure Interacts with single-strand break repair proteins XRCC1, XRCC4, ADPRT and p53/TP53. Interacts with NCL. Interacts (via FHA-like domain) with MDC1 (phosphorylated).
Sequence Similarities Contains 1 C2H2-type zinc finger. Contains 1 FHA-like domain. Contains 1 HIT domain.
