Descriptions

The mouse DNA methyltransferase-1 (DNMT1), composed of a replication foci-targeting domain (RFD), a DBA-binding CXXC domain, a pair of bromo-adjacent homology (BAH) domains, and a C-terminal catalytic domain bound to DNA-containing unmethylated CpG sites, mediates maintenance of genomic methylation patterns. The CXXC specifically binds to unmethylated CpG dinucleotide and positions the CXXC-BAH1 linker between the DNA and the active site of DNMT1, preventing de novo methylation. Therefore, unmethylated CpG dinucleotides are occluded from the active site to ensure that only hemimethylated CpG dinucleotides undergo methylation.

Functions

Description
EC Number 2.1.1.37 Methyltransferases
Subcellular Localization
  • Nucleus
  • Cytoplasm
  • 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

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
heterochromatin A compact and highly condensed form of chromatin that is refractory to transcription.
neuronal cell body The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
pericentric heterochromatin Heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by methylated H3 histone at lysine 9 (H3K9me2/H3K9me3).
protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
replication fork The Y-shaped region of a replicating DNA molecule, resulting from the separation of the DNA strands and in which the synthesis of new strands takes place. Also includes associated protein complexes.
