Application Notes
This Dnmt3a antibody is useful for Immunohistochemistry on paraffin-embedded sections, Immunoprecipitation, Immunocytochemistry/Immunofluorescence and Western Blot, where a band should be seen at ~120 kDa. NOTE: This antibody does not neutralize the enzymatic activity of its corresponding methyltransferase. In ICC/IF, nuclear and cytoplasmic staining was observed in Ntera-2 cells. In IHC-P, staining was observed in the cytoplasm of mouse testis. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.

Background: DNMT3A

Methylation of cytosine residues is essential for mammalian development by regulating gene expression, gene silencing and genomic imprinting (1). This process is controlled by the enzyme DNA (cytosine-5)-methyltransferase 3A (DNMt3a), which is encoded by the DNMT3A gene and has a predicted molecular weight of 102 kDa. DNA methyltransferases including DNMt3a are involved in de novo cytosine methylation and maintenance of embryonic and somatic cells through the transfer of methyl groups to specific CpG structures in DNA (2). Somatic mutations in DNMT3A are responsible for cytogenetically normal acute myeloid leukemia (CN-AML). Hypermethylation of CpG islands in tumor suppressor genes or hypomethylation of bulk genomic DNA are linked with cancer (3,4). Mutations in the DNMT3A gene have also been found to cause DNMT3A overgrowth syndrome and myelodysplastic syndromes.
