    Sumoylation of the human histone H4 tail inhibits p300-mediated transcription by RNA polymerase II in cellular extracts

    Calvin Jon A Leonen, Miho Shimada ... Champak Chatterjee
    Chemically sumoylated histone H4 shows negative biochemical crosstalk with gene-activating histone acetylation and methylation marks, and directly inhibits RNA polymerase II-mediated gene transcription.

    A synthetic biology approach to probing nucleosome symmetry

    Yuichi Ichikawa, Caitlin F Connelly ... Paul D Kaufman
    A novel system for expression of asymmetric nucleosomes in vivo enables mechanistic studies on histone modification readouts in the cell.

    SUV39 SET domains mediate crosstalk of heterochromatic histone marks

    Alessandro Stirpe, Nora Guidotti ... Thomas Schalch
    Clr4, a highly conserved SUV39 histone methyltransferase, requires its SET domain to sense histone H3K14 ubiquitination in order to maintain heterochromatin and H3K9 methylation.

    Independent manipulation of histone H3 modifications in individual nucleosomes reveals the contributions of sister histones to transcription

    Zhen Zhou, Yu-Ting Liu ... Jin-Qiu Zhou
    A yeast genetic model for studying the function of sister histones in chromatin dynamics.

    Telomere dysfunction cooperates with epigenetic alterations to impair murine embryonic stem cell fate commitment

    Mélanie Criqui, Aditi Qamra ... Lea Harrington
    Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.

    The conformation of the histone H3 tail inhibits association of the BPTF PHD finger with the nucleosome

    Emma A Morrison, Samuel Bowerman ... Catherine A Musselman
    The BPTF PHD finger is inhibited from binding the methylated H3 tails in the context of the nucleosome due to their robust interaction with the nucleosomal DNA, which can be modulated by additional histone PTMs.

    Crosstalk within a functional INO80 complex dimer regulates nucleosome sliding

    Oliver Willhoft, Elizabeth A McCormack ... Dale B Wigley
    Regulation of the INO80 chromatin remodelling complex differs from those identified in other chromatin remodellers and involves a C-terminal domain of the Ino80 subunit.

    Structural basis for PRC2 decoding of active histone methylation marks H3K36me2/3

    Ksenia Finogenova, Jacques Bonnet ... Jürg Müller
    Nucleosome binding by PRC2 threads H3K27 into its active site via an interaction network set in register by unmodified H3K36.

    Histone H3 threonine 11 phosphorylation by Sch9 and CK2 regulates chronological lifespan by controlling the nutritional stress response

    Seunghee Oh, Tamaki Suganuma ... Jerry L Workman
    Histone H3T11 phosphorylation regulates chronological lifespan by linking nutritional stress-response signals to chromatin.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo, Fabio Mohn ... Robert Schneider
    The acetylation of histones at specific sites close to DNA can regulate transcription.
