    Dynamic multifactor hubs interact transiently with sites of active transcription in Drosophila embryos

    Mustafa Mir, Michael R Stadler ... Michael B Eisen
    The probability of transcription factors binding to their target sites is choreographed through the formation of dynamic multi-protein hubs that transiently interact with actively transcribing genes.

    C. elegans GLP-1/Notch activates transcription in a probability gradient across the germline stem cell pool

    ChangHwan Lee, Erika B Sorensen ... Judith Kimble
    Analyzing the readout of Notch signaling with single RNA precision reveals that active transcription sites are the most accurate measure of Notch-dependent transcriptional activation.

    Constitutive turnover of histone H2A.Z at yeast promoters requires the preinitiation complex

    Michael Tramantano, Lu Sun ... Ed Luk
    The transcription machinery is required for the disassembly of the promoter-proximal H2A.Z nucleosome, contributing to the constitutive histone turnover at yeast promoters.

    Synthetic and genomic regulatory elements reveal aspects of cis-regulatory grammar in mouse embryonic stem cells

    Dana M King, Clarice Kit Yee Hong ... Barak A Cohen
    The independent effects of transcription factor binding sites are large regardless of sequence context, but the interactions between sites are context dependent.

    CDK9-dependent RNA polymerase II pausing controls transcription initiation

    Saskia Gressel, Björn Schwalb ... Patrick Cramer
    CDK9 inhibition in human cells uncovers that Pol II pause duration regulates the frequency of productive transcription initiation.

    Genome-wide dynamics of Pol II elongation and its interplay with promoter proximal pausing, chromatin, and exons

    Iris Jonkers, Hojoong Kwak, John T Lis
    The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.

    Intrinsic control of muscle attachment sites matching

    Alexandre Carayon, Laetitia Bataillé ... Jean-Louis Frendo
    Making a link between deletion of transcription cis-regulatory elements by CrispR/Cas9, obtention of mutants with single muscle morphology defects and their impact on locomotion.

    The mechanism of variability in transcription start site selection

    Libing Yu, Jared T Winkelman ... Richard H Ebright
    Variability in bacterial transcription start site selection involves DNA “scrunching” and “anti-scrunching,” which may represent a general mechanism for start site selection in all organisms.

    Mouse B2 SINE elements function as IFN-inducible enhancers

    Isabella Horton, Conor J Kelly ... Edward B Chuong
    An epigenomic analysis in mouse macrophages reveals that a highly abundant transposable element exhibits activity as an immune inducible regulatory element.

    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.
