catalytic activity:The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.,disease:Defects in OGG1 are a cause of renal cell carcinoma (RCC1) [MIM:144700].,disease:Defects in OGG1 are associated with tumor formation.,function:DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N-methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta-lyase activity that nicks DNA 3' to the lesion.,similarity:Belongs to the type-1 OGG1 family.,tissue specificity:Ubiquitous.,
Nucleus, nucleoplasm . Nucleus speckle . Nucleus matrix . Together with APEX1 is recruited to nuclear speckles in UVA-irradiated cells.; [Isoform 1A]: Nucleus.; [Isoform 2A]: Mitochondrion.
Ubiquitous.
