    An ESCRT-LEM protein surveillance system is poised to directly monitor the nuclear envelope and nuclear transport system

    David J Thaller, Matteo Allegretti ... C Patrick Lusk
    ESCRT-driven mechanisms that sense and seal holes in the nuclear membranes directly monitor the nuclear transport system and the exposure of the inner nuclear membrane.

    Distinct ‘safe zones’ at the nuclear envelope ensure robust replication of heterochromatic chromosome regions

    Hani Ebrahimi, Hirohisa Masuda ... Julia Promisel Cooper
    The nuclear periphery houses compositionally and functionally distinct domains, one of which provides a 'safe zone' for replication and reassembly of heterochromatic genome regions.

    Exportin Crm1 is repurposed as a docking protein to generate microtubule organizing centers at the nuclear pore

    Xun X Bao, Christos Spanos ... Kenneth E Sawin
    Microtubule nucleation from the nuclear envelope in fission yeast involves repurposing of nuclear export proteins for a non-export-related function, docking cytoplasmic proteins at nuclear pore complexes.

    Mechanisms of chromosome biorientation and bipolar spindle assembly analyzed by computational modeling

    Christopher Edelmaier, Adam R Lamson ... Meredith D Betterton
    A computational model of fission yeast mitosis can interrogate mechanisms required for successful mitosis, the origin of spindle length fluctuations, and spindle force balance during assembly.

    HIV-1 nuclear import in macrophages is regulated by CPSF6-capsid interactions at the nuclear pore complex

    David Alejandro Bejarano, Ke Peng ... Hans-Georg Kräusslich
    Interaction of HIV capsids with the cellular protein cleavage-and-polyadenylation factor 6 at the inner side of nuclear pores promotes nuclear entry of the viral replication complex in primary human macrophages.

    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.

    Age-dependent deterioration of nuclear pore assembly in mitotic cells decreases transport dynamics

    Irina L Rempel, Matthew M Crane ... Liesbeth M Veenhoff
    In replicative ageing yeast cells, an age-dependent impediment in proper assembly of nuclear pore complexes is associated with altered nuclear transport.

    Physical basis of the cell size scaling laws

    Romain Rollin, Jean-François Joanny, Pierre Sens
    A theoretical model explains how protein density and nuclear to cell volume ratio are maintained during cell growth, discusses conditions under which this breaks down, and highlights the importance of metabolites, mainly amino acids such as glutamate, in this homeostasis.

    The Lamin B receptor is essential for cholesterol synthesis and perturbed by disease-causing mutations

    Pei-Ling Tsai, Chenguang Zhao ... Christian Schlieker
    Lamin B receptor may provide a long-sought model system enabling unprecedented studies of protein quality control in the nuclear envelope of mammalian cells.

    An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae

    Annemarie Kralt, Matthias Wojtynek ... Karsten Weis
    Genetic, proteomic, and structural analyses provide insight into the role of Brl1 during nuclear pore complex biogenesis, suggesting a function in the fusion of outer and inner nuclear membranes.
