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.

1 GO annotations of cellular component

Name Definition
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.

4 GO annotations of molecular function

Name Definition
DNA (cytosine-5-)-methyltransferase activity Catalysis of the reaction
DNA binding Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
promoter-specific chromatin binding Binding to a section of chromatin that is associated with gene promoter sequences of DNA.
zinc ion binding Binding to a zinc ion (Zn).

1 GO annotations of biological process

Name Definition
methylation The process in which a methyl group is covalently attached to a molecule.
