Function 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. Has also 8-oxo-7,8-dihydroguanine (8-oxoG) DNA glycosylase activity. Acts preferentially on DNA damage opposite guanine residues in DNA. Is able to process lesions in nucleosomes without requiring or inducing nucleosome disruption. {ECO:0000269|PubMed:10882850, ECO:0000269|PubMed:11328882, ECO:0000269|PubMed:11380260, ECO:0000269|PubMed:11695910, ECO:0000269|PubMed:12140329, ECO:0000269|PubMed:12144783, ECO:0000269|PubMed:12519758, ECO:0000269|PubMed:14734554, ECO:0000269|PubMed:1553383
