    Modularity and determinants of a (bi-)polarization control system from free-living and obligate intracellular bacteria

    Matthieu Bergé, Sébastien Campagne ... Patrick H Viollier
    Common ancestries, activities and structural determinants of a modular (bi-)polarization control system encoded in free-living and obligate intracellular α-proteobacteria, including the rickettsial pathogens, are described.

    Functional dichotomy and distinct nanoscale assemblies of a cell cycle-controlled bipolar zinc-finger regulator

    Johann Mignolet, Seamus Holden ... Patrick H Viollier
    Forward genetics and super-resolution microscopy identifies ZitP as a conserved multifunctional regulator that accumulates at both cell extremities in distinct macromolecular structures to perform different functions in the asymmetric model bacterium Caulobacter crescentus.

    Experimental reconstitution of chronic ER stress in the liver reveals feedback suppression of BiP mRNA expression

    Javier A Gomez, D Thomas Rutkowski
    Feedback mechanisms that contribute to the deactivation of the unfolded protein response lead to the dysregulation of mRNA expression during chronic stress in the liver, including that of the critical endoplasmic reticulum chaperone BiP.

    An essential cell-autonomous role for hepcidin in cardiac iron homeostasis

    Samira Lakhal-Littleton, Magda Wolna ... Peter A Robbins
    The novel role of hepcidin in cell-autonomous iron regulation changes our understanding of tissue-specific iron control, and of its interplay with systemic iron homeostasis.

    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.
