    Daple is a novel non-receptor GEF required for trimeric G protein activation in Wnt signaling

    Nicolas Aznar, Krishna K Midde ... Pradipta Ghosh
    Daple is a guanine nucleotide-exchange factor (GEF) for trimeric G proteins that enables Wnt/Frizzled receptors to transactivate G proteins during non-canonical Wnt signaling.

    The unfolded protein response is required for dendrite morphogenesis

    Xing Wei, Audrey S Howell ... Kang Shen
    The unfolded protein response regulates neuronal dendrite morphogenesis by controlling the folding of a transmembrane leucine-rich repeat (LRR) protein.

    Kinetochore-independent chromosome segregation driven by lateral microtubule bundles

    Christina C Muscat, Keila M Torre-Santiago ... Sarah M Wignall
    Chromosomes in C. elegans female reproductive cells segregate through motor-driven movement along lateral microtubule bundles.

    MAF1 represses CDKN1A through a Pol III-dependent mechanism

    Yu-Ling Lee, Yuan-Ching Li ... Ming-Ta Hsu
    Pol II-mediated transcription and chromatin looping of CDKN1A are repressed by MAF1 through the regulation of Pol III activity.

    Differential cell autonomous responses determine the outcome of coxsackievirus infections in murine pancreatic α and β cells

    Laura Marroqui, Miguel Lopes ... Decio L Eizirik
    Pancreatic α and β cells have different cell autonomous signatures; this explains why α but not β cells can clear infections by potentially diabetogenic viruses.

    Identification of a lipid scrambling domain in ANO6/TMEM16F

    Kuai Yu, Jarred M Whitlock ... H Criss Hartzell
    The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

    ULK3 regulates cytokinetic abscission by phosphorylating ESCRT-III proteins

    Anna Caballe, Dawn M Wenzel ... Juan Martin-Serrano
    ULK3 is a kinase in the abscission checkpoint that temporarily inactivates ESCRT-III proteins via phosphorylation, which is required to delay cytokinesis in response to defects in mitosis.

    Structural evidence for Scc4-dependent localization of cohesin loading

    Stephen M Hinshaw, Vasso Makrantoni ... Stephen C Harrison
    Cohesin loading at centromeres depends on a conserved surface cluster of amino-acid residues on the cohesin loading protein, Scc4.

    The homo-oligomerisation of both Sas-6 and Ana2 is required for efficient centriole assembly in flies

    Matthew A Cottee, Nadine Muschalik ... Susan M Lea
    The structure of the Ana2 Central Coiled-Coil Domain provides insight into how centriolar cartwheel components may be recruited and assembled, and indicates that cartwheel assembly involves more than just SAS-6 oligomerisation.

    The Caenorhabditis elegans protein SAS-5 forms large oligomeric assemblies critical for centriole formation

    Kacper B Rogala, Nicola J Dynes ... Ioannis Vakonakis
    SAS-5 forms oligomers, through a trimeric coiled coil and novel dimeric domain, that are necessary for centriolar localisation of SAS-5 and for centriole duplication.
