UniProtKB accession:  Q08214

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bifunctional DNA N-glycosylase with associated apurinic/apyrimidinic (AP) lyase function that catalyzes the first step in base excision repair (BER), the primary repair pathway for the repair of oxidative DNA damage. The DNA N-glycosylase activity releases the damaged DNA base from DNA by cleaving the N-glycosidic bond, leaving an AP site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination. Primarily recognizes and repairs oxidative base damage of pyrimidines, but also purine-derived lesions, alkylation damage as well as abasic sites. Can also repair the oxidation products of 8-oxoguanine.
