    AMPK and vacuole-associated Atg14p orchestrate μ-lipophagy for energy production and long-term survival under glucose starvation

    Arnold Y Seo, Pick-Wei Lau ... Jennifer Lippincott-Schwartz
    Upon AMPK activation by acute glucose restriction, Atg14p shifts its distribution from ER exit sites to liquid-ordered membrane domains on the vacuolar surface where, together with Atg6p, it facilitates LD-specific autophagy (i.e., microautophagy of lipid droplets) for energy production and long-term survival of starved cells.

    Mechanotransduction current is essential for stability of the transducing stereocilia in mammalian auditory hair cells

    A Catalina Vélez-Ortega, Mary J Freeman ... Gregory I Frolenkov
    The remarkable lifelong stability of mechanotransducing stereocilia of the inner ear hair cells depends on the activity of the transduction ion channels located at the tips of these mechanosensory projections.

    Inhibitor of ppGalNAc-T3-mediated O-glycosylation blocks cancer cell invasiveness and lowers FGF23 levels

    Lina Song, Adam D Linstedt
    The first inhibitor identified against an iso-enzyme that initiates O-glycosylation in the Golgi complex promises new therapeutic approaches for cancer and chronic kidney disease.

    Dilation of fusion pores by crowding of SNARE proteins

    Zhenyong Wu, Oscar D Bello ... Erdem Karatekin
    A few SNARE complexes suffice to fuse membranes, but many more are needed to dilate the nascent fusion pore by molecular crowding for efficient neurotransmitter or hormone release during exocytosis.

    Competition between Tropomyosin, Fimbrin, and ADF/Cofilin drives their sorting to distinct actin filament networks

    Jenna R Christensen, Glen M Hocky ... David R Kovar
    Both cooperative and competitive associations of actin binding proteins with actin filaments help drive the self-organization of functionally diverse F-actin networks in fission yeast.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung, Stephanie S Lam ... Alice Y Ting
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    Palmitoylated SCP1 is targeted to the plasma membrane and negatively regulates angiogenesis

    Peng Liao, Weichao Wang ... Xin Ge
    Palmitoylation recruits the phosphatase SCP1 to endothelial cell membranes where it negatively regulates Akt kinase activity, resulting in suppressed angiogenesis and decreased tumorigenesis.

    Dual leucine zipper kinase-dependent PERK activation contributes to neuronal degeneration following insult

    Martin Larhammar, Sarah Huntwork-Rodriguez ... Trent A Watkins
    Two seemingly distinct cellular stress response pathways that contribute to neurodegeneration after axonal insults are now revealed to be under the control of a single master regulator of the neuronal injury response, the kinase DLK.

    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.
