| Application: | DNMT1 (DNA methyltransferase 1) has been used for RNA electrophoretic mobility shift assay (REMSA) to determine the role of extra-coding RNAs (ecRNAs) in controlling neuronal DNA methylation, through interaction with DNA methyltransferases. |
| Application: | Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. |

| Biochem/physiol Actions: | DNMT1 (DNA methyltransferase 1) is the predominant enzyme that is responsible for maintaining the level of DNA methylation. It is responsible for replicating CpG methylation patterns from parent to daughter DNA strands, thus, creating heritable methylation signatures through cell division. It, therefore, maintains epigenetic state of DNA. Abnormalities in the expression of this protein are linked with the progression and prognosis of multiple cancers, such as hepatocellular carcinoma, pancreatic, lung and bladder cancers. Up-regulation of this protein in GC (gastric cancer) with less differentiation, advanced stage and increased rate of mortality. Upregulation of the DNMT1 gene indicates poor prognosis in malignant cancers including renal cell carcinoma, lymphoma, pancreatic and and bladder cancer. |
| General description: | DNMT1 (DNA methyltransferase 1) is a member of the DNMT enzyme family which also includes DNMT2, DNMT3A, and DNMT3B. It is a multidomain protein composed of 1616 amino acids. It has a methyltransferase domain in its C-terminal, which shows sequence homology to bacterial methyltransferases. |
| General description: | The DNMT1 gene is mapped to human chromosome 19p13.2. |
| Physical form: | Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20 and 10% glycerol. |
| Preparation Note: | Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles. |
| Unit Definition: | One unit is defined as the amount of enzyme required to methylate 1 pmol of DNA substrate/min at 37°C. |
