DNMT1 (DNA methyltransferase 1; also MCMT and CXXC-type Zn finger protein 9) is a 190 kDa member of the C5-methyltransferase family of enzymes. It is ubiquitous in expression, and appears during the S-phase of the cell cycle. DNMT1 catalyzes the attachment of a methyl group to the C5 position of CpG cytosines using AdoMet/adenosylmethionine as a co factor. This acts to silence select genes during X chromosome inactivation and tumorigenesis. Human DNMT1 is 1616 amino acids (aa) in length. It contains an N-terminal regulatory, homodimerization and target recognition region (aa 1-1100), a Gly-Lys linker segment (aa 1109-1120) and a catalytic domain (aa 1121-1616). It is acetylated, phosphorylated, and SUMOylated. There are multiple splice variants. There is a deletion of aa 1-336, alternative start sites at Met122 and 62 aa upstream of the standard start site, and a 17 aa substitution for Pro149. Over aa 1381-1587, human DNMT1 shares 87% aa identity with mouse DNMT1.

The role of DNMT3B in the co-incidence of methyltransferase and tumor suppressor expression in malignancies Epigenetics is the process of heritable change in gene activity despite alteration of the hosts DNA sequence, essentially causing a change in a phenotype without a change in the genotype of a host. To change the gene sequence without interfering w... Read full blog post. |

The role of DNMT3A in development Epigenetics is the study of heritable change in gene activity despite alteration of the hosts DNA sequence. Change in gene activity done independently of the DNA sequence is achieved by way of histone and DNA methylation. Gene silencing in DNA ... Read full blog post. |

Controlling Epigenetic Signaling with Dnmt1 and Dnmt3b Dnmt1 belongs to the C5-methyltransferase family that repairs cytosines in dsDNA using a nucleophilic attack mechanism. Dnmt1 is the most abundant mammalian DNA methyltransferase. It is the key methylation maintenance enzyme for both DNA replication/r... Read full blog post. |
