WebJun 11, 2009 · Nevertheless, potential hDOT1L inhibitors will need to be used with caution as hDOT1L is the only known H3K79 methyltransferase and its genetic disruption in mice results in embryonic lethality. 41 In … WebAug 3, 2015 · Interestingly, hDot1L can bind both unmodified and ubiquitylated nucleosomes , with only the latter interaction being conducive to H3K79 methylation. The role of H2B-Ub might, therefore, be to prevent nonproductive hDot1L–nucleosome interactions, which dominate in unmodified nucleosomes, through a physical “corralling” …

WebFeb 2, 2016 · Our biochemical studies indicate that this interaction is required for stimulation of hDot1L activity and leads to a repositioning of hDot1L on the nucleosomal surface, which likely places the active site of the enzyme proximal to H3K79. Collectively, our data converge on a possible mechanism for hDot1L stimulation in which H2B-Ub physically ... WebJun 5, 2008 · This establishes that hDot1L(1–416) is able to bind to both ubiquitylated and unmodified nucleosomes under the conditions of our assays, even though efficient methyltransferase activity is only observed on ubiquitylated nucleosomes. Thus it is likely that uH2B, possibly through an allosteric mechanism, allows hDot1L to bind …
WebApr 1, 2016 · The enzymatic activity of hDOT1L is critical to the pathogenesis of MLL, because methyltransferase-deficient hDot1L is capable of suppressing growth of MLL_fusion-transformed cells. hDot1L-mediated H3-K79 methylation of MLL target genes in leukemogenesis implies that the HMTase activity of hDot1L can be targeted for …
