    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.

    Bidirectional helical motility of cytoplasmic dynein around microtubules

    Sinan Can, Mark A Dewitt, Ahmet Yildiz
    Unlike other cytoskeletal motors that produce torque in a specific direction, cytoplasmic dynein generates torque in either direction, resulting in bidirectional helical motility along microtubules.

    The human cytoplasmic dynein interactome reveals novel activators of motility

    William B Redwine, Morgan E DeSantis ... Samara L Reck-Peterson
    Using a proximity-dependent labeling approach in living cells, the human cytoplasmic dynein-1 interactome was identified and a new family of dynein activators, ninein and ninein-like, was discovered.

    Cytoplasmic dynein crosslinks and slides anti-parallel microtubules using its two motor domains

    Marvin E Tanenbaum, Ronald D Vale, Richard J McKenney
    The motor domains of dynein are sufficient to crosslink microtubules and slide them antiparallel to each other.

    A novel mechanism of bulk cytoplasmic transport by cortical dynein in Drosophila ovary

    Wen Lu, Margot Lakonishok ... Vladimir I Gelfand
    Cortical dynein performs bulk cytoplasmic transport by gliding microtubules along the cell cortex and through the ring canals to the oocyte.

    Cytoplasmic dynein-1 cargo diversity is mediated by the combinatorial assembly of FTS–Hook–FHIP complexes

    Jenna R Christensen, Agnieszka A Kendrick ... Samara L Reck-Peterson
    The combinatorial assembly of different adaptor complexes is a mechanism that dynein uses to interact with multiple cargos.

    Chemical structure-guided design of dynapyrazoles, cell-permeable dynein inhibitors with a unique mode of action

    Jonathan B Steinman, Cristina C Santarossa ... Tarun M Kapoor
    Analyses of the chemical structure of ciliobrevins led to dynein inhibitors with improved properties and higher potency.

    Cryo-EM of dynein microtubule-binding domains shows how an axonemal dynein distorts the microtubule

    Samuel E Lacey, Shaoda He ... Andrew P Carter
    Relion was used to solve structures of microtubules decorated with dynein microtubule-binding domains revealing that an axonemal dynein distorts the microtubule cross-sectional curvature.

    Uni-directional ciliary membrane protein trafficking by a cytoplasmic retrograde IFT motor and ciliary ectosome shedding

    Muqing Cao, Jue Ning ... William J Snell
    During cilium-generated signaling, ciliary membrane protein trafficking is unidirectional and ciliary membrane protein composition is regulated through action in the cytoplasm of the retrograde intraflagelllar transport (IFT) motor and shedding of ciliary ectosomes.

    Molecular basis for dyneinopathies reveals insight into dynein regulation and dysfunction

    Matthew G Marzo, Jacqueline M Griswold ... Steven M Markus
    A mutagenesis screen in budding yeast sheds light on dynein regulation and function, and reveals the molecular basis for disease in patients suffering from neuropathies caused by dynein dysfunction.
