General annotation (Comments)
| Function | Methylates CpG residues. Preferentially methylates hemimethylated DNA. Associates with DNA replication sites in S phase maintaining the methylation pattern in the newly synthesized strand, that is essential for epigenetic inheritance. Associates with chromatin during G2 and M phases to maintain DNA methylation independently of replication. It is responsible for maintaining methylation patterns established in development. DNA methylation is coordinated with methylation of histones. Mediates transcriptional repression by direct binding to HDAC2. In association with DNMT3B and via the recruitment of CTCFL/BORIS, involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9 By similarity. |
| Catalytic activity | S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine. |
| Subunit structure | Homodimer. Interacts with HDAC1 and with PCNA. Forms a complex with DMAP1 and HDAC2, with direct interaction. Forms also a stable complex with E2F1, BB1 and HDAC1. Binds MBD2 and MBD3. Component of complexes containing SUV39H1. Interacts with DNMT3A and DNMT3B By similarity. Binds annexin V Potential. Interacts with the PRC2/EED-EZH2 complex. Interacts with UBC9 and BAZ2A/TIP5 By similarity. Binds to CSNK1D. Interacts with BAZ2A/TIP5. Binds to CSNK1D. Interacts with UHRF1; promoting its recruitment to hemimethylated DNA. Interacts with USP7, promoting its deubiquitination By similarity. |
| Subcellular location | |
| Tissue specificity | Isoforms 0 and 8 are highly expressed in placenta, brain, lung, spleen, kidney, heart, and at much lower levels in liver. Isoform 1 is expressed in cerebellum, isoform 2 in muscle and testis, isoform 3 in lung, isoform 4 in spleen and brain, and isoform 5 in brain. |
| Domain | The N-terminal part is required for homodimerization and acts as a regulatory domain. The CXXC-type zinc finger specifically binds to unmethylated CpG dinucleotides, positioning the autoinhibitory linker between the DNA and the active site, thus providing a mechanism to ensure that only hemimethylated CpG dinucleotides undergo methylation By similarity. |
| Post-translational modification | Sumoylated By similarity. Acetylation on multiple lysines, mainly by KAT2B/PCAF, regulates cell cycle G2/M transition. Deacetylation of Lys-1116 and Lys-1354 by SIRT1 increases methyltransferase activity By similarity. Phosphorylation of Ser-151 by CDKs is important for enzymatic activity and protein stability. Phosphorylation of Ser-140 by AKT1 prevents methylation by SETD7 therebye increasing DNMT1 stability By similarity. Methylation at Lys-139 by SETD7 promotes DNMT1 proteasomal degradation By similarity. Ubiquitinated by UHRF1; interaction with USP7 counteracts ubiquitination by UHRF1 by promoting deubiquitination and preventing degradation by the proteasome By similarity. |
| Sequence similarities | Belongs to the C5-methyltransferase family. Contains 2 BAH domains. Contains 1 CXXC-type zinc finger. |
