    Intermolecular epistasis shaped the function and evolution of an ancient transcription factor and its DNA binding sites

    Dave W Anderson, Alesia N McKeown, Joseph W Thornton
    Experimental mapping of the joint sequence space of an ancient transcription factor (TF) and its DNA binding sites reveals that epistasis across the molecular interface permitted the evolution of a new and specific TF-DNA complex.

    Mechanisms governing target search and binding dynamics of hypoxia-inducible factors

    Yu Chen, Claudia Cattoglio ... Xavier Darzacq
    Live-cell single particle tracking reveals the intrinsically disordered regions of transcription factors playing an unanticipated role in the nuclear search and chromatin binding process leading to functional target site selectivity and gene activation.

    Missense mutations in CRX homeodomain cause dominant retinopathies through two distinct mechanisms

    Yiqiao Zheng, Chi Sun ... Shiming Chen
    The integrated analysis of multi-omics and functional evidence both in vitro and in knock-in mouse models reveal novel gain-of-function pathogenic mechanisms of dominant CRX HD missense mutations.

    Enforcement of developmental lineage specificity by transcription factor Oct1

    Zuolian Shen, Jinsuk Kang ... Dean Tantin
    Oct1 replaces Oct4 at critical targets shortly after ESC differentiation to promote expression of lineage-specific genes and repress lineage-inappropriate genes.

    An efficient targeted nuclease strategy for high-resolution mapping of DNA binding sites

    Peter J Skene, Steven Henikoff
    CUT&RUN (Cleavage Under Targets & Release Using Nuclease) profiles antibody-targeted DNA-binding proteins in situ with high resolution and low background, providing a simple, robust and scalable alternative to chromatin immunoprecipitation.

    Nucleosomes influence multiple steps during replication initiation

    Ishara F Azmi, Shinya Watanabe ... Stephen P Bell
    Nucleosomal DNAs assembled or modified by different chromatin remodeling enzymes differentially impact the origin licensing and helicase activation steps of replication initiation.

    Casposase structure and the mechanistic link between DNA transposition and spacer acquisition by CRISPR-Cas

    Alison B Hickman, Shweta Kailasan ... Fred Dyda
    The tetrameric structure of a casposase bound to DNA and its biochemical properties show how a transposase could have evolved to perform CRISPR-Cas spacer acquisition.

    BRCT domains of the DNA damage checkpoint proteins TOPBP1/Rad4 display distinct specificities for phosphopeptide ligands

    Matthew Day, Mathieu Rappas ... Laurence H Pearl
    Structural and biochemical analyses of BRCT domain interactions defines TOPBP1/Rad4 selectivity for phosphorylated motifs, allowing identification of new interactions, and providing insights into assembly of different TOPBP1-scaffolded DNA repair complexes.

    Rhodopsin targeted transcriptional silencing by DNA-binding

    Salvatore Botta, Elena Marrocco ... Enrico Maria Surace
    Photoreceptor genomic binding of a 20 base-pair-long DNA sequence by a synthetic DNA-binding protein turns off Rhodopsin expression.

    A simple mechanism for integration of quorum sensing and cAMP signalling in Vibrio cholerae

    Lucas M Walker, James RJ Haycocks ... David C Grainger
    Overlapping DNA-binding specificity allows global transcription factors to cooperatively bind the same DNA sites and integrate two signals in the control of gene expression.
