    The KASH5 protein involved in meiotic chromosomal movements is a novel dynein activating adaptor

    Ritvija Agrawal, John P Gillies ... Morgan E DeSantis
    KASH5 uses an EF-hand domain to directly interact with the light intermediate chain of dynein, promotes processive dynein motility, and facilitates dynein recruitment to the nuclear envelope during prophase I of meiosis.

    Hypoxia controls plasma membrane targeting of polarity proteins by dynamic turnover of PI4P and PI(4,5)P2

    Juan Lu, Wei Dong ... Yang Hong
    When challenged by energetic stresses triggered by hypoxia and ATP inhibition, plasma membrane PI4P and PIP2 in cells undergo dramatic turnovers that have profound impact on many cellular processes including electrostatic PM targeting of numerous polybasic proteins.

    CAMSAP2 organizes a γ-tubulin-independent microtubule nucleation centre through phase separation

    Tsuyoshi Imasaki, Satoshi Kikkawa ... Ryo Nitta
    CAMSAP2 co-condensates with αβ-tubulin to induce microtubule nucleation and growth, serving as a microtubule-organizing centre for non-centrosomal microtubules.

    TUBA1A tubulinopathy mutants disrupt neuron morphogenesis and override XMAP215/Stu2 regulation of microtubule dynamics

    Katelyn J Hoff, Jayne E Aiken ... Jeffrey K Moore
    The mechanistic origins of distinct brain malformations associated with different substitutions at α-tubulin residue 409 are examined, revealing disruption of neuronal migration and microtubule regulation by XMAP215 that scales from protein to tissue.

    Functional coupling between TRPV4 channel and TMEM16F modulates human trophoblast fusion

    Yang Zhang, Pengfei Liang ... Huanghe Yang
    A previously unknown calcium channel in human placental trophoblasts provides a calcium source for activating TMEM16F lipid scramblase that flip-flops phospholipids on cell surface, demonstrating a physiological mechanism that helps to understand how lipid dynamics regulates cell fusion.

    Cystathionine-β-synthase is essential for AKT-induced senescence and suppresses the development of gastric cancers with PI3K/AKT activation

    Haoran Zhu, Keefe T Chan ... Jian Kang
    Cystathionine-β-synthase is a novel metabolic regulator of AKT-induced senescence and a potential tumor suppressor in gastric cancer pathogenesis which can be harnessed to target PI3K/AKT-driven cancers.

    Tongue immune compartment analysis reveals spatial macrophage heterogeneity

    Ekaterini Maria Lyras, Karin Zimmermann ... Alexander Mildner
    The tongue is a unique barrier organ, which is constantly exposed to environmental pathogens, and therefore is expected to host an immune cell network ensuring local immune defence, which we characterised during development, health, and disease.

    Oscillatory movement of a dynein-microtubule complex crosslinked with DNA origami

    Shimaa A Abdellatef, Hisashi Tadakuma ... Keiko Hirose
    A pair of microtubules, ensembles of oppositely oriented axonemal dyneins, and inter-microtubule crosslinkers are the minimum components needed for oscillation and repetitive bending motions.
