5mC marks are placed on genomic DNA via DNA methyltransferases (DNMTs). There are 5 DNMTs in humans: DNMT1, DNMT2, DNMT3A, DNMT3B, and DNMT3L, and in algae and fungi 3 more are present (DNMT4, DNMT5, and DNMT6). DNMT1 contains the replication foci targeting sequence (RFTS) and the CXXC domain which catalyze the addition of 5mC marks. RFTS directs D… WebJul 19, 2024 · The dynamic methylation status of 5mC is maintained by the antagonistic action of TET and TDG. On one hand, 5mC is stepwise oxidized by TET proteins to produce 5hmC, 5fC, and 5caC. On the other hand, TDG acts on 5fC and 5caC as a glycosylase to regenerate unmodified cytosine (C) through the BER pathway (Figure 2 ).
