Arabidopsis Histone Lysine Methyltransferases.
In eukaryotes, changes in chromatin structure regulate the access of gene regulatory sequences to the transcriptional machinery and play important roles in the repression of transposable elements, thereby protecting genome integrity. Chromatin dynamics and gene expression states are highly correlated, with DNA methylation and histone post-translational modifications playing important roles in t...
متن کاملAssay development for histone methyltransferases.
Epigenetic modifications play a crucial role in human diseases. Unlike genetic mutations, however, they do not change the underlying DNA sequences. Epigenetic phenomena have gained increased attention in the field of cancer research, with many studies indicating that they are significantly involved in tumor establishment and progression. Histone methyltransferases (HMTs) are a large group of en...
متن کاملChemical Probes of Histone Lysine Methyltransferases
Growing evidence suggests that histone methyltransferases (HMTs, also known as protein methyltransferases (PMTs)) play an important role in diverse biological processes and human diseases by regulating gene expression and the chromatin state. Therefore, HMTs have been increasingly recognized by the biomedical community as a class of potential therapeutic targets. High quality chemical probes of...
متن کاملHistone H2A ubiquitination inhibits the enzymatic activity of H3 lysine 36 methyltransferases.
Histone H3 lysine 27 (H3K27) methylation and H2A monoubiquitination (ubH2A) are two closely related histone modifications that regulate Polycomb silencing. Previous studies reported that H3K27 trimethylation (H3K27me3) rarely coexists with H3K36 di- or tri-methylation (H3K36me2/3) on the same histone H3 tails, which is partially controlled by the direct inhibition of the enzymatic activity of H...
متن کاملCancers and the NSD family of histone lysine methyltransferases.
Both genetic and epigenetic alterations are responsible for the stepwise initiation and progression of cancers. Only epigenetic aberrations can be reversible, allowing the malignant cell population to revert to a more benign phenotype. The epigenetic therapy of cancers is emerging as an effective and valuable approach to both the chemotherapy and the chemoprevention of cancer. The utilization o...
