    A novel ALS-associated variant in UBQLN4 regulates motor axon morphogenesis

    Brittany M Edens et al.
    A novel ALS-associated variant in UBQLN4 impairs proteasome function and beta-catenin degradation to drive aberrant axon morphogenesis in motor neurons.

    ATM regulation of IL-8 links oxidative stress to cancer cell migration and invasion

    Wei-Ta Chen et al.
    The ATM kinase has an unanticipated role in tumor progression through the regulation of cell migration by oxidative stress.

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

    Qi Zhang et al.
    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.

    The yeast H+-ATPase Pma1 promotes Rag/Gtr-dependent TORC1 activation in response to H+-coupled nutrient uptake

    Elie Saliba et al.
    The H+ influx coupled to nutrient uptake and the plasma membrane H+-ATPase are central actors of the activation of target of rapamycin complex 1 (TORC1) in budding yeast Saccharomyces cerevisiae..

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

    ESCRT-III drives the final stages of CUPS maturation for unconventional protein secretion

    Amy J Curwin et al.
    The release of Acb1 protein from yeast cells requires the ESCRT-III complex to stabilize the compartment for unconventional protein secretion (CUPS).
