In biochemistry, the DNA methyltransferase (DNA MTase, DNMT) family of enzymes catalyze the transfer of a methyl group to DNA. DNA methylation serves a wide variety of biological functions. All the known DNA methyltransferases use S-adenosyl methionine (SAM) as the methyl donor.

The maintenance DNA methyltransferase (DNMT) 1 and the de novo methyltransferases DNMT3A and DNMT3B are all essential for mammalian development. DNA methylation, catalyzed by the DNMTs, plays an important role in maintaining genome stability.

The DNA methyltransferase (DNMT) family comprises a conserved set of DNA-modifying enzymes that have a central role in epigenetic gene regulation. Recent studies have shown that the functions of the canonical DNMT enzymes - DNMT1, DNMT3A and DNMT3B - go beyond their traditional roles of establishing …

2017年10月16日 · DNMTs are important for normal mammalian development, and DNMT mutations are associated with several human diseases, including cancer. The DNA methyltransferase (DNMT) family comprises a...

DNA methyltransferases (DNMTs) are the writers of the epigenome. DNMTs are a highly conserved family of proteins present in nearly all life on earth. In mammals, there are 3 major DNMTs: DNMT1, DNMT3a and DNMT3b. DNMT1 is a maintenance DNMT, while DNMT3a and 3b are de novo DNMTs.

Dnmt1 forms part of the family of DNA methyltransferase enzymes, which consists primarily of DNMT1, DNMT3A, and DNMT3B. This enzyme is responsible for maintaining DNA methylation, which ensures the fidelity of this epigenetic patterns across cell divisions.

DNA methylation is an epigenetic mark that living beings have used in different environments. The MTases family catalyzes DNA methylation. This process is conserved from archaea to eukaryotes, from fertilization to every stage of development, and …

DNA methyltransferase (DNMT) inhibitors can activate silenced genes at low doses and cause cytotoxicity at high doses. The ability of DNMT inhibitors to reverse epimutations is the basis of their use in novel strategies for cancer therapy. In this review, we examined the literature on DNA methyltransferase inhibitors.

2024年12月24日 · DNMT1 (DNA Methyltransferase 1) is a Protein Coding gene. Diseases associated with DNMT1 include Cerebellar Ataxia, Deafness, And Narcolepsy, Autosomal Dominant and Neuropathy, Hereditary Sensory, Type Ie. Among its related pathways are RNA Polymerase I Promoter Opening and Signaling by ALK fusions and activated point mutants.

2025年1月17日 · DNA methylation, catalyzed by DNA methyltransferases (DNMT), plays pivotal role in regulating embryonic development, gene expression, adaption to environmental stress, and maintaining genome integrity. DNMT family consists of DNMT1, DNMT3A, DNMT3B, and the enzymatically inactive DNMT3L.
