General description
Human DNA methyltransferase 1 (Dnmt1) is a 1616 amino acids protein; the N-terminal two-thirds of the protein is considered to be the regulatory domain, while the C-terminal region contains the catalytic domain.
In humans, the gene encodes a DNA (cytosine-5)-methyltransferase with 1616 amino acids. The N-terminal contains the regulatory domain, while the C-terminal region contains the catalytic domain. Two isoforms of DNMT1 have been isolated, DNMT1a and DNMT1b, the difference residing in 16 extra amino acids within the latter.
Immunogen
synthetic peptide corresponding to amino acids 1581-1595 of rat DNMT1, conjugated to KLH via an N-terminal added lysine residue. The sequence is conserved in human and mouse.
Application
Anti-DNMT1 antibody produced in rabbit has been used in western blot analysis, and staining for confocal laser scanning microscopy.
Biochem/physiol Actions
DNA methyltransferase 1 (Dnmt1) is part of different complexes; it can establish a repressive transcription complex consisting of the histone deacetylase 4 (HDAC4), DNA methyltransferase 1-associated Protein (DMAP1) and DNMT1 itself. Consistent with the role of DNA methylation in gene silencing, DNMT1 can associate with HDAC1 and MECP2 (methyl CpG binding protein 2).
DNMT1 protein is important for the maintenance of methylation, as well as for the novo methylation activities occurring in somatic cells of vertebrates. It establishes a repressive transcription complex at replication foci with histone deacetylase HDAAC4 and DMAP1.

The study of CpG methylation of genomic DNA in neurons has emerged from the shadow of cancer biology into a fundamental investigation of neuronal physiology. This advance began with the discovery that catalytic and receptor proteins related to the insertion

Hypermethylation is associated with the silencing of tumour susceptibility genes in several forms of cancer; however, the mechanisms responsible for this aberrant methylation are poorly understood. The prototypic DNA methyltransferase, DNMT1, has been widely assumed to be responsible for most
