TranscriptomicsComparative histone modification profiling revealed developmentally regulated acetylation on upstream promoters of C4 genes and potential C4 regulators
We analysed genome-wide histone H3 lysine 4 trimethylation and histone H3 lysine 9 acetylation, two modifications typically associated with active genes, in meristematic cells at the base and expanding cells in the maturing zone of the maize (Zea mays) leaf. These data were compared to transcript le...

ProteomicsFast light changes promote distinct responses of plastid protein acetylation marks
Protein acetylation is a key recurring co- and posttranslational modification. How different types of acetylation respond to the same environmental stress is unknown. A member of the newly discovered family of plastid acetyltransferases (GNAT2), which is featuring both lysine- and N-terminal acetyl...

ProteomicsIntegrated lysine acetylation stoichiometry and proteomics analysis in human cells
Lysine acetylation is a widespread posttranslational modification that targets a large number of biological pathways. Recent studies reveal that lysine acetylation sites exhibit mainly low stoichiometry. Here we explored three sample preparation methods, the use of detergents for the chemical acetyl...

GenomicsIdentification of 67 histone marks and histone lysine crotonylation as a new type of histone modification
We report the identification of 67 previously undescribed histone modifications, increasing the current number of known histone marks by about 70%. We further investigated one of the marks, lysine crotonylation (Kcr), confirming that it represents an evolutionarily-conserved histone posttranslationa...

ProteomicsGlobal profiling of acetylation reveals a new family with dual-specific lysine and N-terminal acetyltransferase activity in the plastids of Arabidopsis
Protein acetylation is a universally conserved modification occurring on N-termini (N--acetylation, NTA) and on internal lysines residues (-lysine-acetylation, KA). So far, NTA and KA were known to be supported by distinct families of enzymes (NATs and KATs, respectively), despite most of them sha...

GenomicsH3K36ac is an evolutionary conserved histone modification that marks active genes in plants
In eukaryotic cells, DNA is tightly packed in the nucleus in chromatin which has histones as its main protein component. Histones are subject to a large number of distinct post-translational modifications, whose sequential or combinatorial action affects genome function. Here, we report the identifi...

TranscriptomicsChromatin immunoprecipitation genome wide map of nucleosome acetylation and methylation in Yeast
Genomes are packaged into nucleosomes whose position and modification state can profoundly influence regulation of gene expression. We have established new ChIP-based high-resolution genome-wide maps of histone acetylation and methylation that take into account changes in nucleosome occupancy at act...

TranscriptomicsTranscription profiling of mouse embryoic fibroblasts expressing wild type MyoD or its non-acetylatable version MyoD RRR to investigate how MyoD acetylation may contribute to differential gene activation.
The transcription factor MyoD can coax na?e fibroblasts or otherwise committed cells to adopt the skeletal muscle phenotype by activating the muscle gene expression program. Activation of muscle gene expression occurs in quantal steps with not all the target genes of MyoD being activated at the same...

GenomicsTranscriptional regulation by H3K122 acetylation in the lateral surface of the histone octamer
We characterize the acetylation of H3K122 for the first time. Towards this we mapped the genomic distribution of H3K122Ac, identified the enzyme introducing H3K122Ac, and addressed the functional contribution H3K122Ac to transcription. We found that H3K122Ac is associated with chromatin marks and ge...
