    Structure of the chromatin remodelling enzyme Chd1 bound to a ubiquitinylated nucleosome

    Ramasubramanian Sundaramoorthy, Amanda L Hughes ... Tom Owen-Hughes
    The unwrapping two turns of DNA on Chd1-bound nucleosomes cause the histone H3 tail and ubiquitin to be re-positioned.

    Human cytomegalovirus IE1 protein alters the higher-order chromatin structure by targeting the acidic patch of the nucleosome

    Qianglin Fang, Ping Chen ... Rui-Ming Xu
    Distinct binding of viral proteins to the same region on the nucleosome surface can result in contrasting changes to higher-order chromatin structure in the host cell.

    Synthetic CpG islands reveal DNA sequence determinants of chromatin structure

    Elisabeth Wachter, Timo Quante ... Adrian Bird
    Genomic landmarks, known generically as ‘CpG islands’, program chromatin structure via their richness in the dinucleotide CG and their skewed composition of DNA bases.

    The structure of the core NuRD repression complex provides insights into its interaction with chromatin

    Christopher J Millard, Niranjan Varma ... John WR Schwabe
    An extensive interface between the proteins RBBP4 and MTA1 defines the three-dimensional architecture of the core NuRD complex and determines the recruitment of the complex to chromatin.

    Nucleosome-CHD4 chromatin remodeler structure maps human disease mutations

    Lucas Farnung, Moritz Ochmann, Patrick Cramer
    The structure of the chromatin remodeller CHD4 bound to a nucleosome reveals differences to the known Chd1-nucleosome complex and maps cancer mutations.

    The human leukemia virus HTLV-1 alters the structure and transcription of host chromatin in cis

    Anat Melamed, Hiroko Yaguchi ... Charles RM Bangham
    The human leukemia virus HTLV-1 causes abnormal chromatin looping in tens of thousands of infected T cell clones in each host, and abnormal host transcription both flanking the integrated provirus and at distant loci in cis.

    Structural reorganization of the chromatin remodeling enzyme Chd1 upon engagement with nucleosomes

    Ramasubramanian Sundaramoorthy, Amanda L Hughes ... Tom Owen-Hughes
    Structural models of the chromatin remodeling enzyme Chd1 in solution and when bound to chromatin indicate that conformational changes to both the enzyme and the nucleosome occur upon nucleotide dependent engagement.

    Distinguishing between recruitment and spread of silent chromatin structures in Saccharomyces cerevisiae

    Molly Brothers, Jasper Rine
    Heterochromatin proteins like the SIR complex in budding yeast use different mechanisms for recruitment to nucleation sites and long-range spread to create a domain of transcriptional silencing.

    Structure and dynamics of the chromatin remodeler ALC1 bound to a PARylated nucleosome

    Luka Bacic, Guillaume Gaullier ... Sebastian Deindl
    Analysis of conformational heterogeneity in cryo-EM data by a recently developed deep learning method reveals the structure and dynamics of the oncogenic chromatin remodeler ALC1 bound to a poly-ADP-ribosylated nucleosome.

    Chromatin structure-dependent histone incorporation revealed by a genome-wide deposition assay

    Hiroaki Tachiwana, Mariko Dacher ... Noriko Saitoh
    A new method using permeabilized cells and recombinant histones enables to analyze histone incorporations at the DNA sequence level.
