這個基因編碼的蛋白質是一種核酸內切酶iii家族的dna n-糖基化酶。與大腸桿菌中的類似蛋白質一樣，編碼的蛋白質在含有氧化嘧啶殘基的dna底物上具有dna糖苷酶活性，并且具有無嘌呤/無嘧啶裂解酶活性。
The protein encoded by this gene is a DNA N-glycosylase of the endonuclease III family. Like a similar protein in E. coli, the encoded protein has DNA glycosylase activity on DNA substrates containing oxidized pyrimidine residues and has apurinic/apyrimidinic lyase activity.
