ProteomicsTwo DOT1 enzymes cooperatively mediate efficient ubiquitin-independent histone H3 lysine 76 tri-methylation in kinetoplastids
In higher eukaryotes, a single DOT1 histone H3 lysine 79 (H3K79) methyltransferase processively produces H3K79me2/me3 from me0 through histone H2B mono-ubiquitin interaction. The early-branched kinetoplastid Trypanosoma brucei harbors the essential H3K76 di-methyltransferase DOT1A and the non-essent...

ProteomicsA Chemical Acetylation based Mass Spectrometry Platform for Histone Profiling
Here we present a strategy for the identification and quantitation of histone methylation that utilizes nondeuterated acetic anhydride to fully acetylate all free lysine residues prior to digestion with trypsin and analysis by LC-MS/MS.

ProteomicsPhosphorylation of methyltransferase Set2p and demethylase Jhd1p and its association with histone H3K36 methylation and stress response pathways in Saccharomyces cerevisiae
Histone lysine methylation is a key epigenetic modification that regulates eukaryotic transcription. In Saccharomyces cerevisiae, it is controlled by a reduced but evolutionarily conserved suite of methyltransferase (Set1p, Set2p, Dot1p, and Set5p) and demethylase (Jhd1p, Jhd2p, Rph1p, and Gis1p) en...

ProteomicsMus musculus brown adipose tissue histone proteoforms
Histones were isolated from brown adipose tissue and liver from mice housed at 28, 22, or 8 C. Quantitative top- or middle-down approaches were used to quantitate histone H4 and H3.2 proteoforms. See published article for complimentary RNA-seq and RRBS datasets.

GenomicsAF9 Links Histone Acetylation to DOT1L-Mediated H3K79 Methylation
The recognition of modified histones by “reader” proteins constitutes a key mechanism regulating gene expression in the chromatin context. Compared with the great variety of readers for histone methylation, few protein modules that recognize histone acetylation are known. Here we show that the evolu...

TranscriptomicsReplicative senescence of mesenchymal stem cells causes DNA methylation changes which correlate with repressive histone marks
Cells in culture undergo replicative senescence. In this study, we analyzed functional, genetic and epigenetic sequels of long‐term culture in human mesenchymal stem cells (MSC). Already within early passages the fibroblastoid colony‐ forming unit (CFU‐f) frequency and the differentiation potential ...

GenomicsEffects of DNA Methylation on Nucleosome Stability
Methylation of DNA at CpG dinucleotides represents one of the most important epigenetic mechanisms involved in the control of gene expression in vertebrate cells. In this report, we conducted high-throughput nucleosome reconstitution experiments on 572 KB of human DNA and 668 KB of mouse DNA that wa...

ProteomicsNon-histone lysine methylation of grape berry
To gain a comprehensive understanding of non-histone methylation during grape berry ripening. A 4D-label free quantitative proteomics approach was used to study the non-histone methylation of lysine during grape berry development and ripening. The ‘Kyoho’ grape berries at EL 31, EL 33, EL 35 and EL ...

ProteomicsComplete loss of H3K9 methylation dissolves mouse heterochromatin organization
Histone H3 lysine 9 (H3K9) methylation is a central epigenetic modification that defines heterochromatin from unicellular to multicellular organisms. In mammalian cells, H3K9 methylation can be catalyzed by at least six distinct SET domain enzymes: Suv39h1/Suv39h2, Eset1/Eset2 and G9a/Glp. We used m...

GenomicsMaintenance of DNA methylation in embryonic stem cells depends on the histone H3K9 methyltransferases (Dnmt3ab KO Methyl-Seq)
During mammalian development DNA methylation patterns need to be reset in primordial germ cells (PGC) and preimplantation embryos. However, many retro-transposons and imprinted genes are resistant to such global epigenetic reprogramming via hitherto undefined mechanisms. Here, we report that some of...
