a DNA methyltransferase required for genome wide de novo methylation and essential for development. DNA methylation is coordinated with methylation of histones. Prefers CpG methylation to CpA, CpT, and CpC methylation. Methylates CpG sites at a rate much slower than DNMT1, but greater than DNMT3b. Methylation is coordinated with methylation of histones. Binds the ZNF238 transcriptional repressor. Interacts with SETDB1 and DNMT1. Can co-localize with heterochromatin protein (HP1 ) and methyl-CpG binding protein (MeCBP). Associates with HDAC1 through its ADD-type zinc-finger. 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.
