    Actin assembly ruptures the nuclear envelope by prying the lamina away from nuclear pores and nuclear membranes in starfish oocytes

    Natalia Wesolowska et al.
    Combined light and electron microscopy reveals a new function for Arp2/3-mediated actin assembly in nuclear envelope rupture, which leads to a separation of nuclear membranes and pores from the lamina.

    Loss of centromere function drives karyotype evolution in closely related Malassezia species

    Sundar Ram Sankaranarayanan et al.
    The centromeres in Malassezia species, by breakage or inactivation, facilitate genome rearrangements that can result in varying karyotypes and contribute to the evolution of these species.

    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    The inner junction complex of the cilia is an interaction hub that involves tubulin post-translational modifications

    Ahmad Abdelzaher Zaki Khalifa et al.
    A structure of the ciliary inner junction at 3.6 Å resolution permits atomic modeling of six inner junction proteins and their interactions with acetylated lysine 40 loops of alpha tubulins.

    Length-dependent disassembly maintains four different flagellar lengths in Giardia

    Shane G McInally et al.
    Giardia, a multi-ciliated parasitic protist, maintains four different flagellar lengths by balancing flagellar length-independent IFT-mediated assembly with length-dependent kinesin-13 mediated disassembly.

    Cryo electron tomography with volta phase plate reveals novel structural foundations of the 96-nm axonemal repeat in the pathogen Trypanosoma brucei

    Simon Imhof et al.
    Cryo electron tomography provides the first high-resolution 3D axoneme structure from any pathogenic organism, revealing novel structures that support the unique motility of these pathogens through host tissues.

    A polyomavirus peptide binds to the capsid VP1 pore and has potent antiviral activity against BK and JC polyomaviruses

    Joshua R Kane et al.
    A peptide derived from BK and JC polyomavirus protein VP2/3 inhibits viral infection by targeting a binding site in the pore of polyomavirus VP1 pentamers, enabling future VP1-targeted therapeutic strategies.

    Degradation of engulfed mitochondria is rate-limiting in Optineurin-mediated mitophagy in neurons

    Chantell S Evans, Erika LF Holzbaur
    In neuronal mitophagy, Parkin and OPTN induce efficient sequestration of damaged somal mitochondria into autophagosomes, but slow turnover via lysosomal acidification may be a point of vulnerability for the cell.

    High fat diet induces microbiota-dependent silencing of enteroendocrine cells

    Lihua Ye et al.
    Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.

    Kinetochores attached to microtubule-ends are stabilised by Astrin bound PP1 to ensure proper chromosome segregation

    Duccio Conti et al.
    Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.
