    Glypicans define unique roles for the Hedgehog co-receptors boi and ihog in cytoneme-mediated gradient formation

    Eléanor Simon, Carlos Jiménez-Jiménez ... Isabel Guerrero
    The glypicans Dally-like protein and Dally reveal functional non-redundancy of the Hedgehog co-receptors Boi and Ihog through independent interactions and specifically regulate cytoneme dynamics via the Ihog FNIII domain, thus setting long-range signaling.

    The mitochondrial permeability transition pore activates the mitochondrial unfolded protein response and promotes aging

    Suzanne Angeli, Anna Foulger ... Gordon Lithgow
    Loss of the F-ATP synthase c-subunit inhibits a pathological mitochondrial permeability transition pore that is coupled to a maladaptive mitochondrial unfolded protein response while also extending lifespan.

    TRPC3 and NALCN channels drive pacemaking in substantia nigra dopaminergic neurons

    Ki Bum Um, Suyun Hahn ... Myoung Kyu Park
    The non-selective Na+ leak channel (NALCN) and the transient receptor potential 3 channel (TRPC3) cooperate in driving pacemaking in substantia nigra dopaminergic neurons.

    Intracellular functions and motile properties of bi-directional kinesin-5 Cin8 are regulated by neck linker docking

    Alina Goldstein-Levitin, Himanshu Pandey ... Larisa Gheber
    Precise hydrogen-bond stabilization of the neck linker docking onto the catalytic motor domain, is crucial for motor activity and intracellular functions of the bi-directional mitotic kinesin-5 Cin8.

    Augmin deficiency in neural stem cells causes p53-dependent apoptosis and aborts brain development

    Ricardo Viais, Marcos Fariña-Mosquera ... Jens Lüders
    Non-centrosomal microtubule nucleation mediated by augmin is essential for neural progenitor mitosis and survival, and thus brain development.

    Distinct roles of nonmuscle myosin II isoforms for establishing tension and elasticity during cell morphodynamics

    Kai Weißenbruch, Justin Grewe ... Martin Bastmeyer
    The mechanical response of adherent cells in structured environments is shown to be shaped by the intricate interplay between the three different isoforms of an essential molecular motor.

    The cAMP effector PKA mediates Moody GPCR signaling in Drosophila blood–brain barrier formation and maturation

    Xiaoling Li, Richard Fetter ... Ulrike Gaul
    A polarized Moody/protein kinase A pathway plays an unrecognized central role in controlling the enormous cell growth and blood–brain barrier integrity in a highly coordinated spatiotemporal manner in brain homeostasis.

    GIV/Girdin, a non-receptor modulator for Gαi/s, regulates spatiotemporal signaling during sperm capacitation and is required for male fertility

    Sequoyah Reynoso, Vanessa Castillo ... Pradipta Ghosh
    Spermatozoa require GIV for specialized compartmentalized signaling to support efficient capacitation while inhibiting premature acrosome reaction.

    Selective dephosphorylation by PP2A-B55 directs the meiosis I-meiosis II transition in oocytes

    S Zachary Swartz, Hieu T Nguyen ... Arminja N Kettenbach
    Time-course phosphoproteomics reveals that selective dephosphorylation is critical for directing the MI/MII transition and that, through its inherent phospho-threonine preference, PP2A-B55 imposes specific phosphoregulated behaviors that distinguish the two meiotic divisions.
