    Structure and mechanism of a Hypr GGDEF enzyme that activates cGAMP signaling to control extracellular metal respiration

    Zachary F Hallberg, Chi Ho Chan ... Ming C Hammond
    A newfound signaling enzyme that diverged from a protein family ubiquitous in bacteria provides mechanistic insights into how new signaling activity emerges to control distinct cellular function and physiology.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye, Nicoletta Commins ... L Stirling Churchman
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Conformational and dynamic plasticity in substrate-binding proteins underlies selective transport in ABC importers

    Marijn de Boer, Giorgos Gouridis ... Thorben Cordes
    Selective import via bacterial ABC importers is facilitated by a hitherto unrecognized complexity in the conformational dynamics of the substrate-binding proteins.

    Targeted degradation of aberrant tau in frontotemporal dementia patient-derived neuronal cell models

    M Catarina Silva, Fleur M Ferguson ... Stephen J Haggarty
    A new Cereblon-recruiting bifunctional tau ligand, QC-01-175, promotes aberrant tau degradation and rescue of stress vulnerability in human neuronal cell models of tauopathy.

    Cryo-EM reveals distinct conformations of E. coli ATP synthase on exposure to ATP

    Meghna Sobti, Robert Ishmukhametov ... Alastair G Stewart
    Cryo-EM studies reveal that incubation with ATP produces conformational intermediates of E. coli ATP synthase, in which the ε subunit is no longer in its autoinhibitory conformation.

    Intramolecular domain dynamics regulate synaptic MAGUK protein interactions

    Nils Rademacher, Benno Kuropka ... Sarah A Shoichet
    Binding of ligands to PSD-95 PDZ domains induces a conformational change within the C-terminal domain module that enables differential binding to synaptic interactors.

    Stepwise activation mechanism of the scramblase nhTMEM16 revealed by cryo-EM

    Valeria Kalienkova, Vanessa Clerico Mosina ... Cristina Paulino
    cryo-EM reveals the properties of distinct conformations occupied during activation of the lipid scramblase nhTMEM16 and provides new insights into its interactions with the lipid environment.

    Schnyder corneal dystrophy-associated UBIAD1 inhibits ER-associated degradation of HMG CoA reductase in mice

    Youngah Jo, Jason S Hamilton ... Russell A DeBose-Boyd
    UBIAD1 mediates a unique geranylgeranyl pyrophosphate-sensing mechanism that when disrupted, inhibits degradation of HMG CoA reductase and triggers overproduction of corneal cholesterol that characterizes the eye disease Schnyder Corneal Dystrophy.

    Regulating G protein-coupled receptors by topological inversion

    Bray Denard, Sungwon Han ... Jin Ye
    Multiple biochemical assays show that the topology of CCR5 and possibly other GPCRs may be inverted by ceramide or other sphingolipids through the process of regulated alternative translocation.

    Structures in multiple conformations reveal distinct transition metal and proton pathways in an Nramp transporter

    Aaron T Bozzi, Christina M Zimanyi ... Rachelle Gaudet
    Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.
