    The membrane-associated proteins FCHo and SGIP are allosteric activators of the AP2 clathrin adaptor complex

    Gunther Hollopeter, Jeffrey J Lange ... Erik M Jorgensen
    Endocytosis is triggered by membrane-associated proteins that transform the clathrin adaptor into an active complex.

    TORC2-dependent protein kinase Ypk1 phosphorylates ceramide synthase to stimulate synthesis of complex sphingolipids

    Alexander Muir, Subramaniam Ramachandran ... Jeremy Thorner
    TORC2-Ypk1 signaling upregulates flux through the sphingolipid pathway not only by increasing the supply of long-chain base precursors, but also by increasing their use in synthesizing complex sphingolipids.

    Real-time observation of signal recognition particle binding to actively translating ribosomes

    Thomas R Noriega, Jin Chen ... Joseph D Puglisi
    The signal recognition particle only stably engages translating ribosome nascent-chain complexes exposing a functional signal sequence.

    The role of IMP dehydrogenase 2 in Inauhzin-induced ribosomal stress

    Qi Zhang, Xiang Zhou ... Hua Lu
    The small molecule Inauhzin possesses a dual targeting ability, and activates p53 by targeting two enzymes—SIRT1 and IMP dehydrogenase 2 (IMPDH2)—which are highly expressed in human cancers.

    Reversal of β cell de-differentiation by a small molecule inhibitor of the TGFβ pathway

    Barak Blum, Adam N Roose ... Douglas A Melton
    Loss of mature β cell identity in diabetes can be prevented and rescued by small molecule inhibitors of the TGFβ pathway.

    Peroxisomal lactate dehydrogenase is generated by translational readthrough in mammals

    Fabian Schueren, Thomas Lingner ... Sven Thoms
    Whole-genome in silico screening for stop codon contexts that produce elevated translational readthrough and peroxisome targeting reveals that in mammals, the amount of lactate dehydrogenase in the peroxisome is controlled by translational readthrough.

    Oscillatory phase separation in giant lipid vesicles induced by transmembrane osmotic differentials

    Kamila Oglęcka, Padmini Rangamani ... Atul N Parikh
    Spontaneous osmoregulation in giant phospholipid vesicles, which is characterized by oscillations in vesicle size and membrane tension, couples to the compositional degrees of freedom at the membrane surface to produce oscillations in domain texture and induce isothermal phase change.

    Counteracting suppression of CFTR and voltage-gated K+ channels by a bacterial pathogenic factor with the natural product tannic acid

    Yajamana Ramu, Yanping Xu ... Zhe Lu
    Tannic acid acts as an ‘antidote’ against the negative effects of a bacterial enzyme, which can both aggravate cystic fibrosis and enable the anthrax bacteria to evade the immune responses elicited by a typical live vaccine.

    Clathrin-independent pathways do not contribute significantly to endocytic flux

    Vassilis Bitsikas, Ivan R Corrêa Jr, Benjamin J Nichols
    Chemical labelling of all primary endocytic vesicles allows the contribution of different endocytic mechanisms to the total endocytic uptake in cultured mammalian cells to be quantified.

    A critical role for mTORC1 in erythropoiesis and anemia

    Zachary A Knight, Sarah F Schmidt ... Jeffrey M Friedman
    Transcription profiling of activated cells using Phospho-Trap, a new method for identifying activated cells, reveals a critical role for mTOR signaling in red blood cell development and the pathogenesis of anemia
