Methylcytosine dioxygenase.
based on mapping to UniProt D2W6T1
DNA 5-methylcytosine + 2-oxoglutarate + O(2) = DNA 5-hydroxymethylcytosine + succinate + CO(2).
-!- Dioxygenase that catalyzes the conversion of the modified genomic base 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC). -!- Might initiate a process leading to cytosine demethylation through deamination into 5-hydroxymethyluracil (5hmU) and subsequent replacement by unmethylated cytosine by the base excision repair system. -!- Methylation at the C5 position of cytosine bases is an epigenetic modification of the mammalian genome which plays an important role in transcriptional regulation.
