Enables damaged DNA binding activity and oxidized purine nucleobase lesion DNA N-glycosylase activity. Involved in several processes, including cellular response to cadmium ion; response to estradiol; and response to folic acid. Located in mitochondrion and nucleus. Biomarker of hepatitis; middle cerebral artery infarction; renal cell carcinoma; status epilepticus; and transient cerebral ischemia. Human ortholog(s) of this gene implicated in several diseases, including Graves' disease; angiomyolipoma; carcinoma (multiple); eye disease (multiple); and reproductive organ cancer (multiple). Orthologous to human OGG1 (8-oxoguanine DNA glycosylase). [provided by Alliance of Genome Resources, Apr 2022]
