    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.

    Regulation of mitochondria-dynactin interaction and mitochondrial retrograde transport in axons

    Catherine M Drerup, Amy L Herbert ... Alex V Nechiporuk
    Actr10, a dynactin pointed end protein, is essential for mitochondrial interaction with the dynein-dynactin retrograde motor and subsequent transport.

    Localised dynactin protects growing microtubules to deliver oskar mRNA to the posterior cortex of the Drosophila oocyte

    Ross Nieuwburg, Dmitry Nashchekin ... Daniel St Johnston
    Dynactin acts as an anti-catastrophe factor that extends microtubule growth; posteriorly elucidating a new essential step in oskar mRNA localisation and providing a novel mechanism by which motor-dependent transport can amplify the polarity of MT networks.

    The role of scaffold reshaping and disassembly in dynamin driven membrane fission

    Martina Pannuzzo, Zachary A McDargh, Markus Deserno
    Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.

    Dynamic clustering of dynamin-amphiphysin helices regulates membrane constriction and fission coupled with GTP hydrolysis

    Tetsuya Takeda, Toshiya Kozai ... Kohji Takei
    A new approach using combination of electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM) clearly demonstrates dynamics of dynamin-amphiphysin complexes during membrane constriction and fission suggesting a novel 'clusterase' model of the dynamin-mediated membrane fission.

    Dynamin phosphorylation controls optimization of endocytosis for brief action potential bursts

    Moritz Armbruster, Mirko Messa ... Timothy A Ryan
    The recycling of transmitter vesicles at synapses shows calcium-dependent regulation that depends on the phosphorylation status of an enzyme called dynamin.

    NuMA recruits dynein activity to microtubule minus-ends at mitosis

    Christina L Hueschen, Samuel J Kenny ... Sophie Dumont
    At mitosis, NuMA recruits dynein-dynactin to microtubule minus-ends, enabling robust microtubule clustering and the emergence of spindle poles.

    Structural inhibition of dynamin-mediated membrane fission by endophilin

    Annika Hohendahl, Nathaniel Talledge ... Aurélien Roux
    The BAR protein endophilin spaces out turns of the dynamin helix, blocking its active conformational change and membrane fission.

    Uncoupling of dynamin polymerization and GTPase activity revealed by the conformation-specific nanobody dynab

    Valentina Galli, Rafael Sebastian ... Aurélien Roux
    Uncoupling of dynamin polymerization and GTPase activity can be induced with dynamin, which allows in vivo visualization of its activity at endocytic pits.

    Cardiolipin targets a dynamin-related protein to the nuclear membrane

    Usha Pallabi Kar, Himani Dey, Abdur Rahaman
    A single amino acid residue is critical for cardiolipin interaction specificity and nuclear membrane recruitment of a dynamin-related protein.
