    The retromer complex safeguards against neural progenitor-derived tumorigenesis by regulating Notch receptor trafficking

    Bo Li et al.
    The retromer complex serves as a bomb squad to retrieve and disarm the potentially harmful pool of Notch receptors in a timely manner and thereby safeguards against brain tumor formation.

    Sec17/Sec18 act twice, enhancing membrane fusion and then disassembling cis-SNARE complexes

    Hongki Song et al.
    Sec17 (αSNAP) and Sec18 (NSF) are shown to act twice, to promote fusion per se and to recycle SNAREs after fusion.

    The multi-subunit GID/CTLH E3 ubiquitin ligase promotes cell proliferation and targets the transcription factor Hbp1 for degradation

    Fabienne Lampert et al.
    Proteomic, biochemical and cell-based analyses of the heterodecameric core GID/CTLH E3 ligase complex reveal its molecular architecture, activity determinants, and function in targeting the tumor suppressor Hbp1 and other substrates required for cell proliferation.

    The interactome of the copper transporter ATP7A belongs to a network of neurodevelopmental and neurodegeneration factors

    Heather S Comstra et al.
    The ATP7A interactome is the first comprehensive view of putative Menkes disease neurodegeneration mechanisms.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    The ER membrane protein complex interacts cotranslationally to enable biogenesis of multipass membrane proteins

    Matthew J Shurtleff et al.
    The ER membrane protein complex promotes the biogenesis of a subset multipass membrane proteins enriched for transporters and other proteins with destabilizing features in transmembrane domains.

    Defective STIM-mediated store operated Ca2+ entry in hepatocytes leads to metabolic dysfunction in obesity

    Ana Paula Arruda et al.
    Store operated calcium entry is defective in hepatocytes of obese mice, and restoring this process is sufficient to improve glucose metabolism.

    Ubiquitin turnover and endocytic trafficking in yeast are regulated by Ser57 phosphorylation of ubiquitin

    Sora Lee et al.
    Ser57 phosphorylation regulates ubiquitin homeostasis by inhibiting deubiquitylase-mediated recycling and promoting vacuolar degradation.

    Fluorescence Lifetime Imaging Microscopy reveals rerouting of SNARE trafficking driving dendritic cell activation

    Daniëlle Rianne José Verboogen et al.
    A novel microscopy-based assay shows that dendritic cells encountering pathogenic stimuli form increased complexes of specific SNARE proteins, driving release of large amounts of inflammatory cytokines.
