Function

DNA glycosylase which prefers single-stranded DNA (ssDNA), or partially ssDNA structures such as bubble and fork structures, to double-stranded DNA (dsDNA). In vitro, displays strong glycosylase activity towards the hydantoin lesions spiroiminodihydantoin (Sp) and guanidinohydantoin (Gh) in both ssDNA and dsDNA; also recognizes FapyA, FapyG, 5-OHU, 5-OHC, 5- OHMH, Tg and 8-oxoA lesions in ssDNA. No activity on 8-oxoG detected. Also shows weak DNA-(apurinic or apyrimidinic site) lyase activity. In vivo, appears to be the primary enzyme involved in removing Sp and Gh from ssDNA in neonatal tissues. Seems to be an important facilitator of cell proliferation in certain populations, for example neural stem/progenitor cells and tumor cells, suggesting a role in replication-associated DNA repair. {ECO:0000269PubMed:20185759, ECO:0000269PubMed:22065741, ECO:0000269PubMed:22569481, ECO:0000269PubMed:22959434, ECO:0000269PubMed:23305905, ECO:0000269PubMed:23313161}.

Disease Associations

Tissue Specificity

Expressed in testis, thymus, spleen and bone marrow. In young mice, expressed at higher levels in thymocytes than splenocytes. At E12, abundant in the subventricular zone (SVZ) of the lateral ventricles. At E17.5 and P0, expression is limited to distinct cells in the cortical SVZ, in cells of the secondary matrix, the dentate gyrus migratory route and the dentate gyrus. {ECO:0000269PubMed:16428305, ECO:0000269PubMed:19170771, ECO:0000269PubMed:19426544, ECO:0000269PubMed:23305905}.
