Cytosine to 5-hydroxymethylcytosine
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 ). Web5-Hydroxymethylcytosine (5-hmC) was discovered back in 1952 and is one of the most important repressive epigenetic modifications. 5-hmC is produced by ten-eleven translocation (TETs) proteins and is an intermediate in 5-mC demethylation process.185 TET proteins can catalyze the oxidation of 5mC at CpG dinucleotides to form 5 …
