    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.

    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.

    Structural basis for COMPASS recognition of an H2B-ubiquitinated nucleosome

    Evan J Worden, Xiangbin Zhang, Cynthia Wolberger
    The structure of the COMPASS methyltransferase bound to an H2B-ubiquitinated nucleosome provides insights into mechanisms of trans-histone cross-talk and the dynamic role of H2B ubiquitination in stimulating histone methylation.

    Explicit ion modeling predicts physicochemical interactions for chromatin organization

    Xingcheng Lin, Bin Zhang
    The physicochemical interactions among wild-type nucleosomes hold substantial significance and play a role in chromatin folding under physiological salt concentrations.

    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.

    Lysine-14 acetylation of histone H3 in chromatin confers resistance to the deacetylase and demethylase activities of an epigenetic silencing complex

    Mingxuan Wu, Dawn Hayward ... Philip A Cole
    Biochemical approaches reveal that an epigenetic histone deacetylase complex called CoREST is slow to deacetylate histone H3 lysine-14 in nucleosomes, and this inhibits demethylation of histone H3 lysine-4 by the CoREST complex.

    Improving drug discovery using image-based multiparametric analysis of the epigenetic landscape

    Chen Farhy, Santosh Hariharan ... Alexey V Terskikh
    A novel phenotypic screening platform based on immunofluorescent imaging of histone modifications enables accurate identification of cell fates and environmental perturbations.

    A map of human PRDM9 binding provides evidence for novel behaviors of PRDM9 and other zinc-finger proteins in meiosis

    Nicolas Altemose, Nudrat Noor ... Simon R Myers
    In humans, specific sequence features can predict whether meiotic recombination occurs at sites bound by the protein PRDM9, whose DNA-binding zinc-finger domain can unexpectedly bind to gene promoters and to other copies of PRDM9.
