Description of YML060W: Mitochondrial glycosylase/lyase that specifically excises 7,8-dihydro-8-oxoguanine residues located opposite cytosine or thymine residues in DNA, repairs oxidative damage to mitochondrial DNA, contributes to UVA resistance[1][2][3][4][5]

S. cerevisiae OGG1 gene was first cloned by functional complementation of E.coli fpg mutY double mutant. However, there is no obvious sequence homology betweeen these two proteins. The Ogg1 protein is conserved in eukaryotes, from yeat to mammals.
