    Ezrin activation by LOK phosphorylation involves a PIP2-dependent wedge mechanism

    Thaher Pelaseyed, Raghuvir Viswanatha ... Anthony Bretscher
    Phosphorylation of ezrin involves an unusual mechanism requiring coincident binding to PIP2 and involvement of the non-catalytic domain to gain access to the phosphorylation site thereby restricting selective phosphorylation to the plasma membrane.

    A computational approach to map nucleosome positions and alternative chromatin states with base pair resolution

    Xu Zhou, Alexander W Blocker ... Erin K O'Shea
    Computational analysis of MNase-seq data reveals that alternatively positioned nucleosomes are prevalent in both yeast and human cells and create significant heterogeneity within cell populations.

    Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner

    Feng-Ching Tsai, Aurelie Bertin ... Patricia Bassereau
    Ezrin, an important actin-membrane linker, can zip adjacent membranes, be enriched to positively-curved membranes when phosphorylated and to negatively-curved membranes through a direct interaction with membrane curvature sensor I-BAR domain proteins.

    ARHGAP18-ezrin functions as an autoregulatory module for RhoA in the assembly of distinct actin-based structures

    Andrew T Lombardo, Cameron AR Mitchell ... Anthony Bretscher
    ARHGAP18 specializes in controlling cell shape at the topmost layer of the cell membrane by regulating the interaction between the ERM protein family, RhoA signaling, and the actin cytoskeleton.

    Unconventional secretory processing diversifies neuronal ion channel properties

    Cyril Hanus, Helene Geptin ... Erin M Schuman
    Imaging, quantitative immunoblotting and mass spectrometry reveal that hundreds of surface-expressed neuronal membrane proteins exhibit atypical glycosylation profiles, resulting in changes in protein half-life and synaptic responses.

    Subcellular sequencing of single neurons reveals the dendritic transcriptome of GABAergic interneurons

    Julio D Perez, Susanne tom Dieck ... Erin M Schuman
    Single somata and dendrites of individual rat neurons were laser-captured and sequenced to discover and compare the subcellular transcriptomes, identifying over 4000 mRNAs in GABAergic dendrites.

    Large-scale cell-type-specific imaging of protein synthesis in a vertebrate brain

    Or David Shahar, Erin Margaret Schuman
    The development of a transgenic zebrafish allows for cell-type-specific labeling of neuronal protein synthesis, enabling brain-wide visualization and quantification of protein synthesis and demonstrating region-specific increases following elevated brain activity.

    Physiology and ecology combine to determine host and vector importance for Ross River virus

    Morgan P Kain, Eloise B Skinner ... Erin A Mordecai
    The role host and vector species play in pathogen transmission cycles is best quantified by integrating species' physiological and ecological competence.

    Temperature explains broad patterns of Ross River virus transmission

    Marta Strecker Shocket, Sadie J Ryan, Erin A Mordecai
    Accounting for nonlinear responses to temperature is critical for accurately predicting how Ross River virus and other mosquito-borne diseases will respond to climate change and detecting the effects of temperature on disease transmission.
