Methylation of DNA at cytosine residues plays an important role in regulation of gene expression, genomic imprinting and is essential for mammalian development. Hypermethylation of CpG islands in tumor suppressor genes or hypomethylation of bulk genomic DNA may be linked with development of cancer. To date, 3 families of mammalian DNA methyltransferase genes have been identified which include Dnmt1, Dnmt2 and Dnmt3. Dnmt1 is constitutively expressed in proliferating cells and inactivation of this gene causes global demethylation of genomic DNA and embryonic lethality. Dnmt2 is expressed at low levels in adult tissues and its inactivation does not affect DNA methylation or maintenance of methylation. The Dnmt3 family members, Dnmt3a and Dnmt3b, are strongly expressed in ES cells but their expression is down regulated in differentiating ES cells and is low in adult somatic tissue. Dnmt1 co-purifies with the retinoblastoma (Rb) tumour suppressor gene product, E2F1, and HDAC1. Dnmt1 also cooperates with Rb to repress transcription from promoters containing E2F-binding sites suggesting a link between DNA methylation, histone deacetylase and sequence-specific DNA binding activity, as well as a growth-regulatory pathway that is disrupted in nearly all cancer cells. NB100-56519 recognizes Dnmt1, a 1616 amino acid protein according to GenBank no. NP_001370.

FAQs for DNMT1 Antibody (NB100-56519). (Showing 1 - 1 of 1 FAQs).
Could you please tell me the size of your DNMT1 protein along with Expression System? I am also doing mutant DNMT1 protein expression using the truncated part (650-1602=952 aa), using bacterial expression system (E.coli, BL21(De3). But right now I am getting some problem that, my size of protein is little higher than my accurate size? I use Auto-induction method to express the protein.
As you can see from our testing data, we see bands at around 185-200 kDa. Full details of the samples can be found on the image captions. Dnmt1,UniProt P26358, is also highly phosphorylated and acetylated which can raise the apparent molecular weight to higher than the predicted molecular weight. This is why you are seeing the change in size compared to what you might expect from your truncated protein.
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.
