Description: 8-hydroxyguanine, a form of oxidative DNA damage induced by free radicals, causesG:C to T:A transversion. In E. coli, three DNA repair enzymes exist to prevent themutagenic effects of 8-hydroxyguanine. One of these enzymes, MutM, was found tohave a functional yeast (yOgg1) and human (hOgg1) homologue.hOgg1 proteins efficiently release the 8-hydroxyguanine opposite the pyrimidine fromDNA and cleave the AP site in a manner similar to bacterial and yeast enzymes. Genetic backgrounds in control of the repair of damaged DNA are involved in thesusceptibility to cancer development. The hOgg1 gene has been mapped to region3p26.2, a region showing loss of heterozygosity (LOH) in a variety of cancers. Inparticular, 3p25-p26 is a common LOH region in lung cancer.Recent work has demonstrated that Ogg plays an important role in CAG expansion, acharacteristic of several neurodegenerative diseases. Ogg appears to be responsiblefor progressive expansion of poly-Q tracts in response to oxidative damage. Thus, Oggprovides a direct link between DNA damage and toxicity in neurons. Alternate Names: anti-8-Oxoguanine DNA-Glycosylase antibody.
