    Structural basis for cytoplasmic dynein-1 regulation by Lis1

    John P Gillies, Janice M Reimer ... Samara L Reck-Peterson
    A 3.1 Å structure of cytoplasmic dynein-1 in complex with its regulator Lis1 reveals the interfaces between dynein and Lis1, all of which are important for dynein function in vitro and in vivo.

    Modelling dynamics in protein crystal structures by ensemble refinement

    B Tom Burnley, Pavel V Afonine ... Piet Gros
    A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

    Lis1 regulates dynein by sterically blocking its mechanochemical cycle

    Katerina Toropova, Sirui Zou ... Andres E Leschziner
    Structural and functional studies reveal how a ubiquitous regulator of dynein keeps the microtubule-based motor in a persistent track-bound state.

    Antiviral function and viral antagonism of the rapidly evolving dynein activating adaptor NINL

    Donté Alexander Stevens, Christopher Beierschmitt ... Matthew D Daugherty
    Evolution-guided functional analyses identify an activating adaptor of the dynein intracellular transportation machinery, NINL, as a novel component of the antiviral immune response and reveal a mechanism by which viruses antagonize NINL function in a species-specific manner.

    Filopodial dynamics and growth cone stabilization in Drosophila visual circuit development

    Mehmet Neset Özel, Marion Langen ... P Robin Hiesinger
    Long-term live imaging in intact developing Drosophila brains reveals a role for N-Cadherin-mediated fast filopodial dynamics and growth cone stabilization during neural circuit assembly.

    Kazrin promotes dynein/dynactin-dependent traffic from early to recycling endosomes

    Ines Hernandez-Perez, Javier Rubio ... María Isabel Geli
    Kazrin, a protein widely expressed in vertebrates whose depletion causes defects in cell adhesion and migration, is recruited to early endosomes and promotes dynein/dynactin-dependent traffic of endocytosed cargo to the recycling endosomes.

    β-cell intrinsic dynamics rather than gap junction structure dictates subpopulations in the islet functional network

    Jennifer K Briggs, Anne Gresch ... Richard KP Benninger
    The functional network of β-cells in the pancreatic islet, which has been used to identify important subpopulations of β-cells implicated in diabetes progression, is indicative of intrinsic dynamics rather than structural communication, implying islet robustness.

    Cortical dynein pulling mechanism is regulated by differentially targeted attachment molecule Num1

    Safia Omer, Samuel R Greenberg, Wei-Lih Lee
    Dynein-dependent microtubule-cortex interactions – "side-on" versus "end-on" pulling – are regulated by cortical ER and mediated by distinct pools of cortical anchor that are differentially localized along the cell periphery.

    Fusion surface structure, function, and dynamics of gamete fusogen HAP2

    Juan Feng, Xianchi Dong ... Timothy A Springer
    Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.

    A Ras-like domain in the light intermediate chain bridges the dynein motor to a cargo-binding region

    Courtney M Schroeder, Jonathan ML Ostrem ... Ronald D Vale
    The dynein light intermediate chain is a member of the G protein superfamily and links the motor to several intracellular cargo adaptors.
