DNA methylation of cytosine, 5-methylcytosine (5mC), is important for ... 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 ).
