The enzyme that copies methylation marks onto newly made DNA, keeping genes silenced. Azacitidine and decitabine trap and destroy it, waking silenced tumour suppressor genes in blood cancers. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Maintenance DNA methyltransferase acting at hemimethylated CpG sites after replication; covalently trapped by incorporated azacytosine.
| Cancer | Prevalence | Measure | Note | Source |
|---|---|---|---|---|
| Metastatic cancer | all% | Housekeeping enzyme present in every dividing cell (methylation maintenance during replication); not a selection marker, which is why these drugs are given by cancer type rather than by test. |
