    An unfolded protein-induced conformational switch activates mammalian IRE1

    G Elif Karagöz, Diego Acosta-Alvear ... Peter Walter
    ER-stress sensing mechanism of the unfolded protein response sensor/transducer IRE1 is conserved from yeast to mammals, where in mammals, unfolded protein binding to IRE1's ER lumenal domain is coupled to its oligomerization and activation through an allosteric conformational change.

    Regulatory coiled-coil domains promote head-to-head assemblies of AAA+ chaperones essential for tunable activity control

    Marta Carroni, Kamila B Franke ... Axel Mogk
    Head-to-head interactions of regulatory coiled-coil domains control activity of the central bacterial AAA+ protein ClpC by promoting formation of a reversible resting state.

    Systematic proteomic analysis of LRRK2-mediated Rab GTPase phosphorylation establishes a connection to ciliogenesis

    Martin Steger, Federico Diez ... Matthias Mann
    Parkinson's kinase LRRK2 phosphorylates a distinct subset of Rabs, and LRRK2-dependent phosphorylation links LRKK2 to ciliogenesis.

    A recombinant BBSome core complex and how it interacts with ciliary cargo

    Björn Udo Klink, Eldar Zent ... Alfred Wittinghofer
    Six BBS proteins form a core BBSome transport vehicle, which is sufficient for recognizing membrane proteins for transport into the ciliary compartment.

    Structure of PINK1 and mechanisms of Parkinson's disease-associated mutations

    Atul Kumar, Jevgenia Tamjar ... Daan MF van Aalten
    The structure of human PINK1 explains structural regulation and clarity on the impact of loss of function disease-associated mutations, which may stimulate future drug discovery efforts for both familial and idiopathic Parkinson's disease.

    Structural insight into TPX2-stimulated microtubule assembly

    Rui Zhang, Johanna Roostalu ... Eva Nogales
    A combination of cryo-electron microscopy of TPX2 bound to microtubules and in vitro reconstitution experiments reveals a novel microtubule interaction mode that explains how TPX2 promotes microtubule nucleation and stabilization.

    A reverse transcriptase ribozyme

    Biswajit Samanta, Gerald F Joyce
    An RNA enzyme is shown to function as a reverse transcriptase, an activity thought to be crucial for the transition from RNA to DNA genomes during the early history of life on Earth.
