General Comments
DOT1L is the only known enzyme to methylate lysine 79 of histone 3 (H3K79), an epigenetic mark associated with active transcription.
DOT1L interacts with translocation partners of the mixed lineage leukemia (MLL) gene, KMT2A, and several MLL oncogenic fusion proteins that are commonly found in human leukemia aberrantly recruit Dot1L to ectopic loci. This causes local hypermethylation of H3K79 and misexpression of genes (including HoxA), which drive the leukemic phenotype. DOT1L has become a promising drug target for the development of pharmacological inhibitors with potential to treat MLL, which currently has limited treatment options and a very poor prognosis.
