    Condensin controls recruitment of RNA polymerase II to achieve nematode X-chromosome dosage compensation

    William S Kruesi et al.
    C. elegans equalizes the expression of X-chromosome genes between the sexes by reducing the recruitment of RNA polymerase II to promoters of X-linked genes in hermaphrodites, using a chromosome-restructuring complex called condensin.

    Mechanism of ubiquitin ligation and lysine prioritization by a HECT E3

    Hari B Kamadurai et al.
    Structural studies reveal the mechanism by which a HECT E3 ubiquitin ligase carries out E2-to-E3-to-substrate ubiquitin transfer and prioritizes target lysines for ubiquitination.

    A global change in RNA polymerase II pausing during the Drosophila midblastula transition

    Kai Chen et al.
    The first zygotic genes are transcribed without RNA polymerase II pausing from a TATA-enriched promoter.

    The structure of the COPII transport-vesicle coat assembled on membranes

    Giulia Zanetti et al.
    A structure of the complete, membrane bound, COPII coat solved by sub-tomogram averaging reveals the arrangement of all protein subunits on the membrane and suggests a mechanism for coating heterogeneously-shaped carriers.

    Complete dissection of transcription elongation reveals slow translocation of RNA polymerase II in a linear ratchet mechanism

    Manchuta Dangkulwanich et al.
    Quantification of all the major on- and off-pathway kinetic parameters in the transcription elongation cycle reveals that RNA polymerase II translocates slowly in a linear, non-branched Brownian ratchet mechanism.

    The human gut and groundwater harbor non-photosynthetic bacteria belonging to a new candidate phylum sibling to Cyanobacteria

    Sara C Di Rienzi et al.
    Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

    Engineered proteins detect spontaneous DNA breakage in human and bacterial cells

    Chandan Shee et al.
    Fluorescent derivatives of a bacteriophage protein that binds double-stranded ends can trap and label genome-destabilizing double-strand DNA breaks in bacterial and human cells, and illuminate the origins of spontaneous DNA breakage in both.

    Expansion of intestinal Prevotella copri correlates with enhanced susceptibility to arthritis

    Jose U Scher et al.
    The sequencing of microbial genomes reveals that the presence of a particular microbial species in the gut may increase the risk of the autoimmune disease rheumatoid arthritis.

    Hdac6 regulates Tip60-p400 function in stem cells

    Poshen B Chen et al.
    A normally cytoplasmic deacetylase, Hdac6, localizes to the nucleus in embryonic stem cells, where it regulates the essential Tip60-p400 chromatin remodeling complex.
