Description
Ogg1 encodes the enzyme responsible for the excision of 8-oxoguanine, a mutagenic base byproduct which occurs as a result of exposure to reactive oxygen. 8-hydroxyguanine, a form of oxidative DNA damage induced by free radicals, causes G:C to T:A transversion. In E. coli, three DNA repair enzymes exist to prevent the mutagenic effects of 8-hydroxyguanine. One of these enzymes, MutM, was found to have a functional yeast (yOgg1) and human (hOgg1) homologue. Ogg1 proteins efficiently release the 8-hydroxyguanine opposite the pyrimidine from DNA 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 the susceptibility to cancer development. The Ogg1 gene has been mapped to region 3p26.2, a region showing loss of heterozygosity (LOH) in a variety of cancers. In particular, 3p25-p26 is a common LOH region in lung cancer. Recent work has demonstrated that Ogg plays an important role in CAG expansion, a characteristic of several neurodegenerative diseases. Ogg appears to be responsible for progressive expansion of poly-Q tracts in response to oxidative damage. Thus, Ogg provides a direct link between DNA damage and toxicity in neurons.
