    Site-specific glycosylation regulates the form and function of the intermediate filament cytoskeleton

    Heather J Tarbet et al.
    The in vivo modification of the canonical intermediate filament protein vimentin with O-linked beta-N-acetylglucosamine affects its function in filament assembly, cell migration and host-pathogen interactions.

    Intermediate Filaments: The sweet side of vimentin

    Natasha T Snider et al.
    A protein modification called O-linked glycosylation regulates the interactions between vimentin molecules under normal conditions, and the ability of Chlamydia bacteria to replicate after they infect cells.

    Formation of retinal direction-selective circuitry initiated by starburst amacrine cell homotypic contact

    Thomas A Ray et al.
    Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.

    Co-translational protein targeting facilitates centrosomal recruitment of PCNT during centrosome maturation in vertebrates

    Guadalupe Sepulveda et al.
    During centrosome maturation, pericentrin is delivered to the centrosome co-translationally by a microtubule- and dynein-dependent process, as pericentrin mRNA is undergoing active translation near the centrosome.

    Free-energy simulations reveal molecular mechanism for functional switch of a DNA helicase

    Wen Ma et al.
    Integration of structural bioinformatics and free-energy simulations reveals how a helicase switches its function from unwinding to rezipping DNA, during which a key metastable conformation is predicted and verified by single-molecule measurements.

    Investigating molecular crowding within nuclear pores using polarization-PALM

    Guo Fu et al.
    The super-resolution fluorescence microscopy approach polarization PALM (p-PALM) reveals that macromolecular crowding and inhomogeneity within nuclear pores generate a structurally and dynamically complex permeability barrier.

    Nonsense mRNA suppression via nonstop decay

    Joshua A Arribere, Andrew Z Fire
    Nonstop mRNA decay degrades mRNAs with a premature stop codon after such mRNAs are targeted by the nonsense-mediated decay machinery.
