    Dissecting the sharp response of a canonical developmental enhancer reveals multiple sources of cooperativity

    Jeehae Park, Javier Estrada ... Angela H DePace
    The sharp expression pattern driven by a classic, simple animal enhancer is determined by multiple molecular mechanisms, not only cooperative binding of the activating transcription factor as was previously thought.

    Ion counting demonstrates a high electrostatic field generated by the nucleosome

    Magdalena Gebala, Stephanie L Johnson ... Dan Herschlag
    First experimental studies on the ion atmosphere around a nucleosome provide a quantitative analysis of the molecule's electrostatic properties.

    A ribosome assembly stress response regulates transcription to maintain proteome homeostasis

    Benjamin Albert, Isabelle C Kos-Braun ... David Shore
    Ribosome assembly is monitored to promote proteostatis through a system whereby unassembled ribosomal proteins lead to activation of heat shock factor 1 and inactivation of the RP gene activator Ifh1.

    Communication between distinct subunit interfaces of the cohesin complex promotes its topological entrapment of DNA

    Vincent Guacci, Fiona Chatterjee ... Douglas E Koshland
    The interface formed where Smc3p and Mcd1p bind each other regulates cohesin DNA binding and cohesion by a mechanism independently from its putative role as a DNA exit gate.

    Determining cellular CTCF and cohesin abundances to constrain 3D genome models

    Claudia Cattoglio, Iryna Pustova ... Anders S Hansen
    Absolute quantification of CTCF and cohesin reveals quantitative constraints on 3D genome organization and illuminates the molecular architecture of the cohesin complex.

    Transcriptome maps of general eukaryotic RNA degradation factors

    Salma Sohrabi-Jahromi, Katharina B Hofmann ... Patrick Cramer
    Mapping of 30 general RNA degradation factors onto the yeast transcriptome provides the global distribution of factors for RNA turnover and surveillance in a eukaryotic cell.

    Protein quality control in the nucleolus safeguards recovery of epigenetic regulators after heat shock

    Maria Azkanaz, Aida Rodríguez López ... Vincent van den Boom
    Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.

    A combination of transcription factors mediates inducible interchromosomal contacts

    Seungsoo Kim, Maitreya J Dunham, Jay Shendure
    A pooled mutational scanning approach for 3D chromosome conformation reveals how multiple transcription factors can jointly specify condition-specific genome conformations.

    Asymmetry between the two acidic patches dictates the direction of nucleosome sliding by the ISWI chromatin remodeler

    Robert F Levendosky, Gregory D Bowman
    Unlike Chd1, ISWI remodelers preferentially shift asymmetric nucleosomes toward the side possessing a wild type acidic patch, regardless of DNA lengths flanking the nucleosome.
