Background InformationCpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. DNMT3 is a developmentally regulated DNA methyltransferase. DNMT3A2 is a second isoform of DNMT3 that is expressed from an alternative promoter. DNMT3A2 localizes to euchromatin and is thought to function in de novo methylation, rather than maintenance methylation. Binding of DNMT3L (DNMT3-like protein) to DNMT3A2 promotes a dramatic reorganization of DNMT3A2 subunits and leads to the formation of specific complexes with enhanced DNA methyltransferase activity. DNMT3A2 targets endogenous DNMT3L to embryonic stem cell chromatin and induces regional DNA methylation.

Entrez Gene Number
Entrez Gene SummaryCpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase that is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes to the cytoplasm and nucleus and its expression is developmentally regulated. Alternative splicing results in multiple transcript variants encoding different isoforms.

UniProt Number
UniProt SummaryFUNCTION:Required for genome wide de novo methylation and is essential for development. DNA methylation is coordinated with methylation of histones. Ref.10

Catalytic activity S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.

SUBUNIT STRUCTURE: Binds the ZNF238 transcriptional repressor. Interacts with SETDB1. Associates with HDAC1 through its ADD-type zinc-finger By similarity. Interacts with DNMT1 and DNMT3B. Interacts with the PRC2/EED-EZH2 complex.

SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Ref.3

TISSUE SPECIFICITY: Highly expressed in fetal tissues, skeletal muscle, heart, peripheral blood mononuclear cells, kidney, and at lower levels in placenta, brain, liver, colon, spleen, small intestine and lung. Ref.7

Sequence similarities Belongs to the C5-methyltransferase family.

Contains 1 ADD-type zinc finger.

Contains 1 PWWP domain.

CAUTION:It is uncertain whether Met-1 or Met-4 is the initiator
