Functioni

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.6 Publications

Catalytic activityi

Removes damaged bases from DNA, leaving an abasic site.
The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.PROSITE-ProRule annotation

Disruption phenotypei

Perinatal mice show reduced regeneration of neural tissue following ischemic brain damage (stroke), associated with fewer activated microglia and impaired neural stem cell proliferation. Aged mice show deficits in learning and memory, decreased anxiety-like behavior, and changes in hippocampal synapse composition. Otherwise viable and fertile.4 Publications

Expressioni

Tissue specificityi

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.4 Publications

Developmental stagei

Highly expressed in the developing brain at E12-E13 when neurogenesis starts. Expression decreases during later development and is undetectable in adult brain.2 Publications

Inductioni

By mitogen stimulation in splenocytes, and by hypoxic-ischemic injury in the striatum and hippocampus.2 Publications
