Dioxygenase that acts as a DNA demethylase(PubMed:18603530). Requires molecular oxygen, alpha-ketoglutarate and iron(PubMed:18603530). Specifically demethylates DNA methylated on the 6th position of adenine(N(6)-methyladenosine) DNA. N(6)-methyladenosine(m6A) DNA is present at some L1 elements in embryonic stem cells and probably promotes their silencing(By similarity). Also able to repair alkylated single-stranded DNA and RNA containing 3-methylcytosine by oxidative demethylation, but with low activity(PubMed:18603530). Also has DNA lyase activity and introduces double-stranded breaks at abasic sites: cleaves both single-stranded DNA and double-stranded DNA at abasic sites, with the greatest activity towards double-stranded DNA with two abasic sites(PubMed:19959401). DNA lyase activity does not require alpha-ketoglutarate and iron and leads to the formation of an irreversible covalent protein-DNA adduct with the 5' DNA product(PubMed:19959401, PubMed:23577621). DNA lyase activity is not required during base excision repair and class switch recombination of the immunoglobulin heavy chain during B lymphocyte activation. May play a role in placental trophoblast lineage differentiation(By similarity).
