    ZMYND10 functions in a chaperone relay during axonemal dynein assembly

    Girish R Mali, Patricia L Yeyati ... Pleasantine Mill
    Chaperoning defects in axonemal dynein subunits trigger proteostatic clearance of dynein motors opening up the possibility of trialling proteostasis modulators to treat the motile ciliopathy primary ciliary dyskinesia (PCD).

    Filament formation by metabolic enzymes is a specific adaptation to an advanced state of cellular starvation

    Ivana Petrovska, Elisabeth Nüske ... Simon Alberti
    A starvation-induced drop in cytosolic pH promotes assembly of budding yeast glutamine synthetase into enzymatically inactive filaments that function as enzyme storage depots.

    An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae

    Annemarie Kralt, Matthias Wojtynek ... Karsten Weis
    Genetic, proteomic, and structural analyses provide insight into the role of Brl1 during nuclear pore complex biogenesis, suggesting a function in the fusion of outer and inner nuclear membranes.

    A pH-driven transition of the cytoplasm from a fluid- to a solid-like state promotes entry into dormancy

    Matthias Christoph Munder, Daniel Midtvedt ... Simon Alberti
    The cytoplasm behaves as an adaptable fluid that can reversibly transition into a protective solid-like state upon stress.

    The molecular appearance of native TRPM7 channel complexes identified by high-resolution proteomics

    Astrid Kollewe, Vladimir Chubanov ... Thomas Gudermann
    High-resolution proteomics in conjunction with biochemical and electrophysiological experiments revealed that the channel-kinase TRPM7 in rodent brain forms macromolecular complexes containing the metal transporters CNNM1-4 and a small G-protein ARL15.

    Symmetric exchange of multi-protein building blocks between stationary focal adhesions and the cytosol

    Jan-Erik Hoffmann, Yessica Fermin ... Eli Zamir
    In the cytosol, the proteins constituting cell-matrix adhesion sites form multi-protein building blocks which enter and leave these sites unaltered, thereby contributing to their rapid and correct self-assembly.

    Automated structure refinement of macromolecular assemblies from cryo-EM maps using Rosetta

    Ray Yu-Ruei Wang, Yifan Song ... Frank DiMaio
    Extensive benchmarking reveals that errors made when manually building models into near-atomic-resolution cryoEM density may automatically be corrected using an improved Rosetta-based structure refinement method.
