DNMT3B (DNA methyltransferase 3B; also DNA MTase HsaIIIB) is a 95-110 kDa member of the C5-methyltransferase family of enzymes. It is ubiquitously expressed in the embryo, and found associated with nuclear pericentric heterochromatin. Pericentric heterochromatin is chromatin composed of satellite repeats that lie adjacent to the centromere. DNA (cytosine-guanine dinucleotides) associated with this area undergos methylation, contributing to gene repression and proper chromosome segregation. Human DNMT3B is 853 amino acids (aa) in length. It contains a PWWP (Pro-Trp-Trp-Pro) domain that binds DNA (aa 225-283), a ADD (ATRX, DNMT3, DNMT3L) domain that contains a Zn-finger and binds to an unmethylated histone H3 tail (aa 423-555), and a class I AdoMet-MTase catalytic region that uses S-adenosyl-L-homocysteine as a substrate for methyl transfer (aa 577-847). There are at least five isoform variants. All show a deletion of aa 365-375. In addition, a second contains an alternative start site 12 aa upstream of the standard site, a third shows a deletion of aa 745-807, a fourth contains a Ser substitution for aa 744-853, while a fifth possesses a 45 aa substitution for aa 768-853. Over aa 1-355, human DNMT3B shares 73% aa sequence identity with mouse DNMT3B.
