DOT1L is an evolutionarily conserved histone methyltransferase which methylates lysine 79 of histone H3 in the core domain. Unlike other histone methyltransferases, the protein does not contain a SET domain, an evolutionary conserved motif, and it specifically methylates nucleosomal histone H3. The protein was originally identified in S. cerevisiae as a disruptor of telomeric silencing. Analysis of the protein sequence revealed no known functional motif other than a putative SAM binding domain. Recent reports also suggests that the protein interacts with AF10, a mixed lineage leukemia fusion partner involved in acute myeloid leukemia, which results in leukemic transformation in a DOT1L methyltransferase activity-dependent manner. Human DOT1L gene is localized in the chromosomal region 19p13.3.
