    The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

    Margaret E Torrence, Michael R MacArthur ... Brendan D Manning
    ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

    A nuclear-based quality control pathway for non-imported mitochondrial proteins

    Viplendra PS Shakya, William A Barbeau ... Adam L Hughes
    During times of mitochondrial impairment, non-imported mitochondrial precursor proteins are targeted to the nucleus for proteasome-dependent degradation.

    PomX, a ParA/MinD ATPase activating protein, is a triple regulator of cell division in Myxococcus xanthus

    Dominik Schumacher, Andrea Harms ... Lotte Søgaard-Andersen
    In the PomX/Y/Z cell division regulatory system, PomX is a PomZ ATPase activating protein, a scaffold for PomX/Y/Z complex formation, and important for fission of the PomX/Y/Z complex during division.

    eIF2B conformation and assembly state regulate the integrated stress response

    Michael Schoof, Morgane Boone ... Peter Walter
    eIF2-P activates the integrated stress response by inducing a conformational change in eIF2B that decreases substrate (eIF2) binding and reduces eIF2B's catalytic activity.

    SABRE populates ER domains essential for cell plate maturation and cell expansion influencing cell and tissue patterning

    Xiaohang Cheng, Magdalena Bezanilla
    SABRE, which is present in a wide range of eukaryotes, localizes to ER subdomains in plants, impacting cell expansion and callose deposition during cell plate maturation.

    Convalescent COVID-19 patients are susceptible to endothelial dysfunction due to persistent immune activation

    Florence WJ Chioh, Siew-Wai Fong ... Christine Cheung
    COVID-19 survivors, who are at risk for vascular complications, would benefit from close monitoring and preventive therapy.

    Genetic disruption of WASHC4 drives endo-lysosomal dysfunction and cognitive-movement impairments in mice and humans

    Jamie L Courtland, Tyler WA Bradshaw ... Scott H Soderling
    Cellular etiology of a human WASH complex mutation in mice reveals its specific roles in neuronal organelle trafficking and a surprising role in motor impairments.

    The SWELL1-LRRC8 complex regulates endothelial AKT-eNOS signaling and vascular function

    Ahmad F Alghanem, Javier Abello ... Rajan Sah
    SWELL1 is required for basal, stretch, and flow-mediated endothelial AKT-eNOS signaling in vitro and protects against angiotensin-induced hypertension and diabetes-associated vascular dysfunction in vivo.

    Physically asymmetric division of the C. elegans zygote ensures invariably successful embryogenesis

    Radek Jankele, Rob Jelier, Pierre Gönczy
    Systematic analysis of C. elegans zygotes manipulated to divide equally demonstrates that daughter cell size asymmetry is critical for proper cell cycle timing, positioning, and fates during subsequent embryogenesis.

    TWIST1 and chromatin regulatory proteins interact to guide neural crest cell differentiation

    Xiaochen Fan, V Pragathi Masamsetti ... Patrick PL Tam
    Network propagation connects TWIST1 with epigenetic regulators CHD7, CHD8, and WHSC1, which collectively promote the bias toward neural crest while suppressing neural stem cell programmes, and subsequently enhance ectomesenchyme potential.
