    Cryo-EM reveals species-specific components within the Helicobacter pylori Cag type IV secretion system core complex

    Michael J Sheedlo et al.
    The structure of a Type IV secretion system provides a framework for understanding assembly of a protein-injection machine.

    The His-Gly motif of acid-sensing ion channels resides in a reentrant ‘loop’ implicated in gating and ion selectivity

    Nate Yoder, Eric Gouaux
    The amino terminus of acid-sensing ion channel 1a forms a reentrant 'loop' that frames the lower pore and harbors a conserved 'His-Gly' motif implicated in gating and ion selectivity mechanisms.

    Live-cell single-molecule tracking highlights requirements for stable Smc5/6 chromatin association in vivo

    Thomas J Etheridge et al.
    In vivo single-molecule imaging demonstrates that Smc5/6 chromatin association depends on ATP hydrolysis and dsDNA binding, requires Nse6 and is modulated by Brc1 after DNA damage.

    Structural analysis of the Legionella pneumophila Dot/Icm type IV secretion system core complex

    Clarissa L Durie et al.
    The structure of the Legionella pneumophilaType IV secretion system provides the detailed molecular model of this complex molecular machine required for pathogenesis.

    Dynamic action of the Sec machinery during initiation, protein translocation and termination

    Tomas Fessl et al.
    The complex process of protein translocation across membranes has been dissected into multiple key steps and the distributions of translocation rates indicate stochastic nature of the reaction.

    Regulation of the Drosophila ID protein Extra macrochaetae by proneural dimerization partners

    Ke Li, Nicholas E Baker
    Developmental genetic and cell culture studies indicate that the Inhibitor of DNA-binding protein Extra macrochaetae (Emc), previously thought to determine where bHLH proteins can act, is itself regulated by those bHLH dimerization partners at the level of protein stability.

    Ambra1 spatially regulates Src activity and Src/FAK-mediated cancer cell invasion via trafficking networks

    Christina Schoenherr et al.
    Ambra1 is a Src "spatial rheostat".

    A novel DNA primase-helicase pair encoded by SCCmec elements

    Aleksandra Bebel et al.
    SCCmec genomic islands encode a novel primase-helicase pair in which priming ability is conferred upon an A-family DNA polymerase domain by a novel protein cofactor.

    SMOC can act as both an antagonist and an expander of BMP signaling

    J Terrig Thomas et al.
    SMOC inhibits BMP signaling locally, but also expands the range of BMP signaling by competing for heparan sulfate binding sites.
