[[http://www.uniprot.org/uniprot/APTX_HUMAN APTX_HUMAN]] 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.<ref>PMID:14755728</ref> <ref>PMID:15044383</ref> <ref>PMID:16547001</ref> <ref>PMID:16964241</ref> <ref>PMID:17276982</ref>
