N-Glycosylase/DNA Lyase, 8-Oxoguanine DNA Glycosylase, DNA-(Apurinic or Apyrimidinic Site) Lyase, AP Lyase, OGG1, MMH, MUTM, OGH1
Human N-Glycosylase/DNA Lyase(OOG1) is a DNA repair enzyme, which belongs to the type-1 OGG1 family. OOG1 incises DNA at 8-oxoG residues, and excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N-methylformamidopyrimidine (FAPY) from damage DNA. It has a beta-lyase activity that nicks DNA 3 to the lesion. OOG1 together with APEX1 is recruited to nuclear speckles in UVA-irradiated cells. The OGG1 gene mutations may be caused Renal cell carcinoma.
