    The mechanism of error induction by the antibiotic viomycin provides insight into the fidelity mechanism of translation

    Mikael Holm, Chandra Sekhar Mandava ... Suparna Sanyal
    The antibiotic viomycin induces errors during initial codon selection by the ribosome by locking the monitoring bases in their active conformation.

    GPIHBP1 expression in gliomas promotes utilization of lipoprotein-derived nutrients

    Xuchen Hu, Ken Matsumoto ... Haibo Jiang
    The expression of the lipoprotein lipase (LPL) transporter GPIHBP1 in glioma capillaries promotes the LPL-mediated processing of triglyceride-rich lipoproteins, thereby providing lipid nutrients for glioma cells.

    tRNA ligase structure reveals kinetic competition between non-conventional mRNA splicing and mRNA decay

    Jirka Peschek, Peter Walter
    Interconnected RNA processing mechanisms ensure the fidelity of non-conventional mRNA splicing during the unfolded protein response.

    Mouse TRPA1 function and membrane localization are modulated by direct interactions with cholesterol

    Justyna B Startek, Brett Boonen ... Karel Talavera
    The activation and membrane localization of the broadly-tuned noxious chemosensory cation channel TRPA1 are regulated by direct interactions with cholesterol via CRAC motifs in transmembane segments 2 and 4.

    Monitoring site-specific conformational changes in real-time reveals a misfolding mechanism of the prion protein

    Ishita Sengupta, Jayant Udgaonkar
    Multi-site FRET measurements of moPrP oligomerization at low pH indicate that major conformational changes take place as monomers reversibly transform into large oligomers, which subsequently disassemble reversibly into small oligomers.

    Ceapins block the unfolded protein response sensor ATF6α by inducing a neomorphic inter-organelle tether

    Sandra Elizabeth Torres, Ciara M Gallagher ... Peter Walter
    Ceapins specifically inhibit the unfolded protein sensor ATF6α by directly tethering the cytosolic domain of ATF6α to ABCD3 in cells and in vitro.

    A toolkit for studying cell surface shedding of diverse transmembrane receptors

    Amanda N Hayward, Eric J Aird, Wendy R Gordon
    The modularity and unequivocal input/response of Notch signaling are harnessed to measure cell-surface shedding of diverse transmembrane receptors to identify new proteolytic switches and detect modulation of proteolysis by therapeutics.

    Cysteine dioxygenase 1 is a metabolic liability for non-small cell lung cancer

    Yun Pyo Kang, Laura Torrente ... Gina M DeNicola
    By increasing intracellular cysteine levels, NRF2 engages a tumor suppressive metabolic pathway mediated by cysteine dioxygenase 1.
