    Site-specific phosphorylation and caspase cleavage of GFAP are new markers of Alexander disease severity

    Rachel A Battaglia, Adriana S Beltran ... Natasha T Snider
    GFAP protein carries a distinct post-translational modification signature that facilitates its pathogenic accumulation and aggregation in astrocytes of patients who succumb to Alexander Disease very early in life.

    Sensing of nutrients by CPT1C regulates late endosome/lysosome anterograde transport and axon growth

    Marta Palomo-Guerrero, Rut Fadó ... Núria Casals
    The pseudoenzyme CPT1C is able to sense changes in intracellular malonyl-CoA levels caused by nutrients or energy stress and regulate late endosomes/lysosomes anterograde transport, necessary for proper axon growth.

    Cell-based HTS identifies a chemical chaperone for preventing ER protein aggregation and proteotoxicity

    Keisuke Kitakaze, Shusuke Taniuchi ... Seiichi Oyadomari
    Cell-based high-throughput screening identifies IBT21 as a chemical chaperone, that inhibits ER protein aggregation and prevents the cell death caused by a proteotoxin, the aggregation-prone prion protein.

    The ribosomal P-stalk couples amino acid starvation to GCN2 activation in mammalian cells

    Heather P Harding, Adriana Ordonez ... David Ron
    Genetic lesions that compromise the ribosome P-stalk implicate direct signalling from the ribosome to the translation initiation factor eIF2 kinase GCN2 in the cellular response to amino acid starvation.

    Impaired lysosomal acidification triggers iron deficiency and inflammation in vivo

    King Faisal Yambire, Christine Rostosky ... Nuno Raimundo
    Impaired lysosomal acidification results in retention of iron inside lysosomes, triggering functional iron deficiency, dysfunctional mitochondria (especially mtDNA loss), and inflammation in vivo in a mouse model of lysosomal disease.

    B cells extract antigens at Arp2/3-generated actin foci interspersed with linear filaments

    Sophie I Roper, Laabiah Wasim ... Pavel Tolar
    Two modes of actin polymerization, branched and linear, cooperate in B cells to extract antigens from surfaces of presenting cells.

    Cycles of autoubiquitination and deubiquitination regulate the ERAD ubiquitin ligase Hrd1

    Brian G Peterson, Morgan L Glaser ... Ryan D Baldridge
    The Hrd1-centric endoplasmic reticulum associated degradation system is regulated by interplay between the system's components.

    Extraction of active RhoGTPases by RhoGDI regulates spatiotemporal patterning of RhoGTPases

    Adriana E Golding, Ilaria Visco ... William M Bement
    Through visualization of directly-labeled RhoGTPase both in vitro and in vivo, RhoGDI is found to spatiotemporally regulate RhoGTPase activity through the extraction of active RhoGTPase.
