Nucleosomes are preferred as substrate compared to free histones. Binds to DNA. Publication Abstract from PubMed Mixed lineage leukemia (MLL) gene rearrangement induces leukemic transformation by ectopic recruitment of disruptor of telomeric silencing 1-like protein (DOT1L), a lysine histone methyltransferase, leading to local hypermethylation of H3K79 and misexpression of genes (including HoxA), which drive the leukemic phenotype. A weak fragment-based screening hit identified by SPR was cocrystallized with DOT1L and optimized using structure-based ligand optimization to yield compound 8 (IC50 = 14 nM). This series of inhibitors is structurally not related to cofactor SAM and is not interacting within the SAM binding pocket but induces a pocket adjacent to the SAM binding site.
