    NuMA-microtubule interactions are critical for spindle orientation and the morphogenesis of diverse epidermal structures

    Lindsey Seldin, Andrew Muroyama, Terry Lechler
    A newly identified microtubule binding activity of NuMA is required for orienting the mitotic spindle.

    Loss of the transcription factor Meis1 prevents sympathetic neurons target-field innervation and increases susceptibility to sudden cardiac death

    Fabrice Bouilloux, Jérôme Thireau ... Frédéric Marmigère
    The transcription factor Meis1 is a dedicated maintenance factor for sympathetic neurons and controls the expression of key genes involved in endosome trafficking.

    Myosin III-mediated cross-linking and stimulation of actin bundling activity of Espin

    Haiyang Liu, Jianchao Li ... Mingjie Zhang
    The tail domain of Myosin III binds to and cross-links actin bundling protein Espin1 and thus modulates higher order actin bundle structures in cellular processes such as stereocilia and microvilli.

    GGGGCC microsatellite RNA is neuritically localized, induces branching defects, and perturbs transport granule function

    Alondra Schweizer Burguete, Sandra Almeida ... Nancy M Bonini
    Expanded repeat RNAs associated with human neurodegenerative diseases can become incorporated into transported granules in neurons, perturbing their function to cause neuritic branching defects.

    The brown adipocyte protein CIDEA promotes lipid droplet fusion via a phosphatidic acid-binding amphipathic helix

    David Barneda, Joan Planas-Iglesias ... Mark Christian
    An interaction between the brown fat protein CIDEA and the phospholipid phosphatidic acid is vital for the expansion of intracellular lipid droplets for energy storage.

    Nanobodies: site-specific labeling for super-resolution imaging, rapid epitope-mapping and native protein complex isolation

    Tino Pleiner, Mark Bates ... Dirk Görlich
    Protocols that greatly simplify the use of nanobodies in fluorescence imaging and affinity purification have been developed.

    Axial contraction and short-range compaction of chromatin synergistically promote mitotic chromosome condensation

    Tom Kruitwagen, Annina Denoth-Lippuner ... Yves Barral
    Condensation and segregation of chromosomes during mitosis is caused by a combination of short-range interactions between nucleosomes and the long-range contraction of chromosome arms mediated by condensin.

    Actin filaments target the oligomeric maturation of the dynamin GTPase Drp1 to mitochondrial fission sites

    Wei-ke Ji, Anna L Hatch ... Henry N Higgs
    A key cellular process is controlled by altering a balance, rather than through an off/on mechanism.

    Planar cell polarity-mediated induction of neural stem cell expansion during axolotl spinal cord regeneration

    Aida Rodrigo Albors, Akira Tazaki ... Elly M Tanaka
    During axolotl spinal cord regeneration adult neural stem cells reactivate an embryonic neuroepithelial cell-like gene program that implements planar cell polarity to orient cell divisions, coupling polarized spinal cord growth with stem cell self-renewal.

    Sister kinetochore splitting and precocious disintegration of bivalents could explain the maternal age effect

    Agata P Zielinska, Zuzana Holubcova ... Melina Schuh
    Multiple age-related changes in chromosome architecture could explain why human oocyte aneuploidy increases with advanced maternal age.
