    Filamin, a synaptic organizer in Drosophila, determines glutamate receptor composition and membrane growth

    GaYoung Lee, Thomas L Schwarz
    Filamin, by recruiting a signaling complex to the postsynapse, orchestrates the correct formation and growth of postsynaptic membranes and localization of glutamate receptor subunits.

    Crenactin forms actin-like double helical filaments regulated by arcadin-2

    Thierry Izoré, Danguole Kureisaite-Ciziene ... Jan Löwe
    Close evolutionary relationship between eukaryotic F-actin and crenarchaeal crenactin protein is supported by a near-atomic cryoEM structure of double helical filaments, that are inhibited by arcadin-2 through binding to crenactin's hydrophobic groove.

    IRBIT controls apoptosis by interacting with the Bcl-2 homolog, Bcl2l10, and by promoting ER-mitochondria contact

    Benjamin Bonneau, Hideaki Ando ... Katsuhiko Mikoshiba
    IRBIT and the Bcl-2 homolog Bcl2l10 form a complex at the endoplasmic reticulum that controls Ca2+ signaling, however IRBIT turns into an apoptosis facilitator following stress and inhibits anti-apoptotic activity of Bcl2l10.

    Quantifying β-catenin subcellular dynamics and cyclin D1 mRNA transcription during Wnt signaling in single living cells

    Pinhas Kafri, Sarah E Hasenson ... Yaron Shav-Tal
    Imaging of single cells within a cell population shows the correlation between subcellular accumulation of β-catenin and the transcriptional activation of a target gene.

    A dynamic mode of mitotic bookmarking by transcription factors

    Sheila S Teves, Luye An ... Robert Tjian
    In contrast to published findings showing exclusion, transcription factors in fact bind mitotic chromosomes in a dynamic fashion, allowing for efficient transmission of transcription programs through mitosis.

    A plasma membrane template for macropinocytic cups

    Douwe M Veltman, Thomas D Williams ... Robert R Kay
    Rings of actin polymerisation that form around PIP3/Ras patches in the cell membrane drive the formation of macropinocytic cups.

    Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration

    Hyo Rim Ko, Il-Sun Kwon ... Jee-Yin Ahn
    Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.

    Differentiation alters stem cell nuclear architecture, mechanics, and mechano-sensitivity

    Su-Jin Heo, Tristan P Driscoll ... Robert L Mauck
    Nuclear reorganization and stiffening accompanies mesenchymal stem cell differentiation, resulting in increased sensitivity to mechanical perturbation.

    Cell culture-based profiling across mammals reveals DNA repair and metabolism as determinants of species longevity

    Siming Ma, Akhil Upneja ... Vadim N Gladyshev
    Profiling of fibroblasts across mammals captures differences in longevity at the level of global gene expression and metabolite levels and reveals pathways that define these differences.
