    Histone H2B ubiquitylation represses gametogenesis by opposing RSC-dependent chromatin remodeling at the ste11 master regulator locus

    Philippe Materne, Enrique Vázquez ... Damien Hermand
    Building on previous work (Materne et al., 2015), it is shown that the ubiquitylation of histone H2B represses cell differentiation by opposing chromatin remodeling at the promoter of the master regulator of gametogenesis, ste11

    Different promoter affinities account for specificity in MYC-dependent gene regulation

    Francesca Lorenzin, Uwe Benary ... Elmar Wolf
    Differences in promoter affinity and MYC levels explain distinct expression profiles induced by physiological and oncogenic MYC.

    Single-molecule imaging of chromatin remodelers reveals role of ATPase in promoting fast kinetics of target search and dissociation from chromatin

    Jee Min Kim, Pat Visanpattanasin ... Carl Wu
    Chromatin remodeling enzymes perform target search by utilizing ATP-binding and hydrolysis to facilitate 1D-diffusion on and rapid detachment from chromatin in living yeast.

    The chromatin remodelers RSC and ISW1 display functional and chromatin-based promoter antagonism

    Timothy J Parnell, Alisha Schlichter ... Bradley R Cairns
    A combination of genetics, expression, genomic localization, and genomic nucleosome profiling demonstrates antagonism between two chromatin remodelers that reveal different mechanisms at different promoter architectures.

    Chromatin is an ancient innovation conserved between Archaea and Eukarya

    Ron Ammar, Dax Torti ... Corey Nislow
    Similarities in the way that nucleosomes are organized into chromatin in archaea and eukaryotes suggest that chromatin might have been involved in gene regulation before its role in DNA packaging evolved.

    Requirements for RNA polymerase II preinitiation complex formation in vivo

    Natalia Petrenko, Yi Jin ... Kevin Struhl
    The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.

    Transcription of a 5’ extended mRNA isoform directs dynamic chromatin changes and interference of a downstream promoter

    Minghao Chia, Amy Tresenrider ... Folkert Jacobus van Werven
    Expression of a 5' extended mRNA isoform represses transcription of a downstream promoter.

    Role of the pre-initiation complex in Mediator recruitment and dynamics

    Elisabeth R Knoll, Z Iris Zhu ... Randall H Morse
    Genome-wide recruitment of Mediator and Pol II is reduced in yeast lacking the Med2-Med3-Med15 tail module triad, and Mediator association with gene promoters depends on Pol II, Taf1, and TBP.

    Promoter-specific changes in initiation, elongation, and homeostasis of histone H3 acetylation during CBP/p300 inhibition

    Emily Hsu, Nathan R Zemke, Arnold J Berk
    CBP/p300 acetylation of histone H3 at promoters and enhancers stimulates transcriptional elongation through recruitment of the super-elongation complex and BRD4.

    The nucleosomal barrier to promoter escape by RNA polymerase II is overcome by the chromatin remodeler Chd1

    Peter J Skene, Aaron E Hernandez ... Steven Henikoff
    The ATP-dependent chromatin remodeler Chd1 controls nucleosome turnover to allow RNA Polymerase to transcribe in vivo.
