General description【一般描述】 | 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. The DNMT1 gene is mapped to human chromosome 19p13.2. |
Application【应用】 | Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. DNMT1 Active human has been used in RNA electrophoretic mobility shift assay. 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. |
Biochem/physiol Actions【生化/生理作用】 | 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. |
