    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Parkin contributes to synaptic vesicle autophagy in Bassoon-deficient mice

    Sheila Hoffmann-Conaway et al.
    The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.

    Translational control of one-carbon metabolism underpins ribosomal protein phenotypes in cell division and longevity

    Nairita Maitra et al.
    Extensive molecular profiling shows how loss of highly similar, paralogous ribosomal proteins lead to distinct phenotypic outputs, through translational control of specific mRNAs.

    Insulin mutations impair beta-cell development in a patient-derived iPSC model of neonatal diabetes

    Diego Balboa et al.
    Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.

    Determination of host proteins composing the microenvironment of coronavirus replicase complexes by proximity-labeling

    Philip V'kovski et al.
    The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.

    Developmentally regulated H2Av buffering via dynamic sequestration to lipid droplets in Drosophila embryos

    Matthew Richard Johnson et al.
    In early Drosophila embryos, histone H2Av continuously exchanges between cytoplasmic lipid droplets, a process that modulates H2Av import into nuclei and constitutes a novel post-translational strategy to regulate nuclear H2Av levels.

    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.

    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 Lamin B receptor is essential for cholesterol synthesis and perturbed by disease-causing mutations

    Pei-Ling Tsai et al.
    Lamin B receptor may provide a long-sought model system enabling unprecedented studies of protein quality control in the nuclear envelope of mammalian cells.

    PTRF/Cavin-1 promotes efficient ribosomal RNA transcription in response to metabolic challenges

    Libin Liu, Paul F Pilch
    PTRF (Cavin-1) mediates metabolism-regulated ribosomal transcription in mature adipocytes, independent of its role in caveolae formation.
