General annotation (Comments)
| Function | Methylates CpG residues. Preferentially methylates hemimethylated DNA. 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. Ref.14 |
| Catalytic activity | S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine. |
| Enzyme regulation | Allosterically regulated. The binding of 5-methylcytosine-containing DNA to the N-terminal parts of DNMT1 causes an allosteric activation of the catalytic domain by a direct interaction of its Zn-binding domain with the catalytic domain. Ref.10 |
| Subunit structure | Interacts with HDAC1 and with PCNA. Binds MBD2 and MBD3. Component of complexes containing SUV39H1. Interacts with DNMT3A and DNMT3B By similarity. Forms a complex with DMAP1 and HDAC2, with direct interaction. Interacts with the PRC2/EED-EZH2 complex. |
| Subcellular location | Nucleus. Cytoplasm. Note: It is nucleoplasmic through most of the cell cycle and associates with replication foci during S-phase. In germ cells, spermatogonia, preleptotene and leptotene spermatocytes all express high levels of nuclear protein, while the protein is not detected in pachytene spermatocytes, despite the fact they expressed high levels of mRNA. In females, the protein is not detected in non-growing oocytes, in contrast to the growing oocytes. During the growing, the protein is no longer detectable in nuclei but accumulates to very high levels first throughout the cytoplasm. At the time of ovulation, all the protein is cytoplasmic and is actively associated with the oocyte cortex. After fecondation, in the preimplantation embryo, the protein remains cytoplasmic and after implantation, it is exclusively nuclear in all tissue types. Isoform 2 is sequestered in the cytoplasm of maturing oocytes and of preimplantation embryos, except for the 8-cell stage, while isoform 1 is exclusively nuclear. Ref.14 |
| Tissue specificity | Isoform 1 is expressed in embryonic stem cells and in somatic tissues. Isoform 2 is expressed in oocytes, preimplantation embryos, testis and in skeletal muscle during myogenesis. |
| Developmental stage | In germ cells, it is present at high levels in spermatogonia and spermatocytes until the pachytene stage, where it falls to undetectable levels. The transient drop at the pachytene stage coincides with the disappearance of the 5.2 kb mRNA and the accumulation of a larger 6.0 kb mRNA. Oocytes accumulate very large amounts of Dnmt1 protein during the growth phase. |
| Miscellaneous | There are three 5' exons, one specific to the oocyte (1c), one specific to the pachytene spermatocyte and also found in skeletal muscle (1b) and one found in somatic cells (1a). Three differents mRNAs can be produced which give rise to two different translation products: isoform 1 (mRNAs-1a) and isoform 2 (mRNA-1b or -1c). |
| Sequence similarities | Belongs to the C5-methyltransferase family. Contains 2 BAH domains. Contains 1 CXXC-type zinc finger. |
