Here, we show that the enhancer-specific histone H3 lysine 4 monomethylation (H3K4me1) and the histone methyltransferases MLL3 and MLL4 (MLL3/4) play an active role in this process. We demonstrate that in differentiating mouse embryonic stem cells, MLL3/4-dependent deposition of H3K4me1 at ...
Lysine residues within histones can be mono-, di - or tri-methylated. In Saccharomyces cerevisiae tri-methylation of Lys 4 of histone H3 (K4/H3) correlates with transcriptional activity, but little is known about this methylation state in higher eukaryotes. Here, we examine the K4/H3 ...
Lysine methylation occurs primarily on histones H3 (Lys4, 9, 27, 36, 79) and H4 (Lys20) and has been implicated in both transcriptional activation and silencing. Methylation of these lysine residues coordinates the recruitment of chromatin modifying enzymes containing methyl-lysine binding modules ...
Monomethylation ofhistoneH3-lysine 4 (H3K4me1) plays an important role for neuronal activity-induced transcription at enhancer sequences (Kim et al., 2010). The highermethylationforms of H3K4, H3K4me3 and H3K4me2 are primarily found at the 5′end of genes, with H3K4me3 mostly arranged as dis...
when histone H4 is monomethylated on lysine 20 (H4K20me1), this common histone modification results in the contraction of chromatin. Restricting the chromatin structure prevents transcription from occurring and reduces gene expression. Alternatively, monomethylation of histone H3 on arginine 17 (H3R17...
The nuclear receptor-binding SET domain (NSD) family which represents a phylogenetically distinct subfamily of HKMTases is responsible for the mono-, and dimethylation of the terminal amino group of lysine in Histone 3 lysine 36 (H3K36), generating H3K36me1 and H3K36me2 (Fig. 1A...
Lysine methylation occurs primarily on histones H3 (Lys4, 9, 27, 36, 79) and H4 (Lys20) and has been implicated in both transcriptional activation and silencing (4). Methylation of these lysine residues coordinates the recruitment of chromatin modifying enzymes containing methyl-lysine binding ...

Methylation Motor Protein Regulation RNA modification Histone post-translational modifications Introduction Lysine methylation in core histones—H2A, H2B, H3, and H4—comes in three ‘flavors’: monomethylation (me1), dimethylation (me2), and trimethylation (me3). Different genomic regions harbor distinc...
