Enables alkylbase DNA N-glycosylase activity. Acts upstream of or within base-excision repair. Predicted to be located in cytosol and nucleoplasm. Is expressed in several structures, including early conceptus; gonad; hemolymphoid system gland; musculature; and placenta. Orthologous to human MPG (N-methylpurine DNA glycosylase).
