    Scaffold nucleoporins Nup188 and Nup192 share structural and functional properties with nuclear transport receptors

    Kasper R Andersen, Evgeny Onischenko ... Thomas U Schwartz
    Components of the nuclear pore complex share structural and functional features with soluble nuclear transport receptors, which suggests that there may be an evolutionary relationship between these two types of protein.

    Nuclear pore heterogeneity influences HIV-1 infection and the antiviral activity of MX2

    Melissa Kane, Stephanie V Rebensburg ... Paul D Bieniasz
    Comprehensive investigation reveals the variability and importance of the nuclear pore complex in HIV-1 infection and the activity of the antiretroviral protein, MX2.

    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.

    Nup98 FG domains from diverse species spontaneously phase-separate into particles with nuclear pore-like permselectivity

    Hermann Broder Schmidt, Dirk Görlich
    How nuclear pore complexes establish their permeability barrier has been a long-standing question; now, this process can be reconstituted by a surprisingly simple and rapid self-assembly of Nup98 FG domains into selective FG phases.

    Detection of TurboID fusion proteins by fluorescent streptavidin outcompetes antibody signals and visualises targets not accessible to antibodies

    Johanna Odenwald, Bernardo Gabiatti ... Susanne Kramer
    Proteins that are low abundant and/or poorly accessible to antibodies can be readily localised with fluorescent streptavidin, when expressed fused to a biotin ligase.

    Ndc1 drives nuclear pore complex assembly independent of membrane biogenesis to promote nuclear formation and growth

    Michael Sean Mauro, Gunta Celma ... Shirin Bahmanyar
    Discovery of how cells couple addition of membranes with insertion of nuclear pore complexes to form and grow the nucleus.

    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.

    DNA circles promote yeast ageing in part through stimulating the reorganization of nuclear pore complexes

    Anne C Meinema, Anna Marzelliusardottir ... Yves Barral
    Acetylation of nuclear basket components, following their interaction with accumulating extrachromosomal DNA circles, drives the reorganization of nuclear pore complexes and the loss of cellular viability associated with replicative ageing.

    Simple biophysics underpins collective conformations of the intrinsically disordered proteins of the Nuclear Pore Complex

    Andrei Vovk, Chad Gu ... Anton Zilman
    Simple biophysical considerations explain the collective behavior of molecularly diverse complex protein assemblies that regulate transport between the nucleus and the cytoplasm in eukaryotic organisms.

    Emerging variants of SARS-CoV-2 NSP10 highlight strong functional conservation of its binding to two non-structural proteins, NSP14 and NSP16

    Huan Wang, Syed RA Rizvi ... Shozeb Haider
    Structure and simulations reveal SARS-CoV-2 NSP10 is more resistant to genetic variations than other SARS-CoV-2 NSPs and that the presence of mutations conserves structural and dynamic changes in NSP10.
