CC -!- FUNCTION: Involved in base excision repair of DNA damaged by oxidation CC or by mutagenic agents. Acts as DNA glycosylase that recognizes and CC removes damaged bases. Has a preference for oxidized purines, such as CC 7,8-dihydro-8-oxoguanine (8-oxoG). Has AP (apurinic/apyrimidinic) lyase CC activity and introduces nicks in the DNA strand. Cleaves the DNA CC backbone by beta-delta elimination to generate a single-strand break at CC the site of the removed base with both 3'- and 5'-phosphates. CC {ECO:0000256|HAMAP-Rule:MF_00103}.
