    Cystatin F (Cst7) drives sex-dependent changes in microglia in an amyloid-driven model of Alzheimer’s disease

    Michael JD Daniels, Lucas Lefevre ... Barry W McColl
    Cst7, a gene coding for protein cystatin F, is expressed by microglia in neurodegenerative disease models and mediates sex-dependent effects on microglial endolysosomal function and disease pathology.

    Mutational analysis to explore long-range allosteric couplings involved in a pentameric channel receptor pre-activation and activation

    Solène N Lefebvre, Antoine Taly ... Pierre-Jean Corringer
    A pentameric channel-receptor was studied by combining allosteric mutations, electrophysiology, fluorescent reporters and normal mode analysis, to dissect the long-range allosteric couplings specifically involved in its pre-activation and activation.

    Adaptation of the periplasm to maintain spatial constraints essential for cell envelope processes and cell viability

    Eric Mandela, Christopher J Stubenrauch ... Iain D Hay
    The bacterial periplasm must adapt to factors effecting the width of the cell envelope.

    Stochastic parabolic growth promotes coexistence and a relaxed error threshold in RNA-like replicator populations

    Mátyás Paczkó, Eörs Szathmáry, András Szilágyi
    An individual-based model framework of sub-exponentially growing replicator systems suggests that parabolic dynamics could have been able to maintain genetic diversity and circumvent the error threshold problem during early evolution.

    Live-cell single-molecule tracking reveals co-recognition of H3K27me3 and DNA targets polycomb Cbx7-PRC1 to chromatin

    Chao Yu Zhen, Roubina Tatavosian ... Xiaojun Ren
    Live-cell single-molecule tracking reveals that hierarchical cooperation within the Polycomb Cbx7 protein between the low-affinity H3K27me3-binding module and the high-affinity DNA-binding cassette targets Polycomb repressive complex 1 to chromatin.

    Acetylcholine acts on songbird premotor circuitry to invigorate vocal output

    Paul I Jaffe, Michael S Brainard
    The neuromodulator acetylcholine contributes to state-dependent modulation of motor vigor and variability by direct action on songbird premotor cortex, bypassing basal ganglia circuitry.

    Sequence co-evolution gives 3D contacts and structures of protein complexes

    Thomas A Hopf, Charlotta P I Schärfe ... Debora S Marks
    Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.

    Stem cells repurpose proliferation to contain a breach in their niche barrier

    Kenneth Lay, Shaopeng Yuan ... Elaine Fuchs
    Adult stem cells sense nearby tissue damage and recruit immune cells to help them direct efforts towards containing a breach in the epithelial barrier.

    Mitochondrial volume fraction and translation duration impact mitochondrial mRNA localization and protein synthesis

    Tatsuhisa Tsuboi, Matheus P Viana ... Brian M Zid
    Mitochondria can tune the protein synthesis of nuclear-encoded proteins through condition-dependent mRNA localization that is regulated by translation elongation and the geometric constraints of the cell.

    Human Nup98 regulates the localization and activity of DExH/D-box helicase DHX9

    Juliana S Capitanio, Ben Montpetit, Richard W Wozniak
    Mechanistic insight into the role of intranuclear Nup98 in gene expression is revealed by functional interactions with the helicase DHX9.
