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. Recently, it has been shown that naturally occurring mutations of Dnmt3b gene occurs in patients with a rare autosomal recessive disorder, termed ICF (immunodeficiency, centromeric instability, and facial anomalies) syndrome.

This antibody was raised against bacteria expressed recombinant full-length mouse Dnmt3b. The antibody also recognizes human Dnmt3b.

Application Notes
This antibody does not react with Dnmt3a.

Dnmt3b Antibody

Western blot analysis for Dnmt3b using IMG-184A at 2 ug/ml against 10 ug of cell lysates of 293 transfected with mouse Dnmt3a (lane 1) and Dnmt3b (lane 2). A protein band of approximate mol. wt. of 110 kDa is only detected in 293 cells transfected with mouse Dnmt3b cDNA.
