| Term | chromosomal 5-methylcytosine DNA demethylation, oxidation pathway | ID (Ontology) | GO:0141167 (Gene Ontology) |
| Definition | An epigenetic cytosine DNA demethylation pathway that starts with the enzymatic oxidation of the 5-methylcytosine (5meC) to generate 5-hydroxymethylcytosine (5hmC), which successively converted to 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC). A DNA glycosylase (e. g. TDG) recognizes the intermediate bases 5fC and 5caC and excises the modified base to initiate its replacement with unmethylated cytosine through base excision repair.[ PubMed:21862972 PubMed:29875631 PubMed:36478523 ] | ||
