DNMT3A Products

Description

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.
