Hydrolysis of the deoxyribose N-glycosidic bond to excise 3-methyladenine, and 7-methylguanine from the damaged DNA polymer formed by alkylation lesions. Belongs to the DNA glycosylase MPG family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
