    Sphingomyelin metabolism controls the shape and function of the Golgi cisternae

    Felix Campelo, Josse van Galen ... Vivek Malhotra
    Association of curvature generating proteins to the Golgi membranes by sphingomyelin metabolism essentially controls the flatness of a Golgi cisterna that is necessary for efficient sorting and export.

    Chimeric origins of ochrophytes and haptophytes revealed through an ancient plastid proteome

    Richard G Dorrell, Gillian Gile ... Chris Bowler
    An in silico reconstruction of a chloroplast that existed hundreds of millions of years ago casts new insights in the evolutionary processes, endosymbioses and chimerism events that shape the origin of plastids.

    Distinct Akt phosphorylation states are required for insulin regulated Glut4 and Glut1-mediated glucose uptake

    Muheeb Beg, Nazish Abdullah ... Timothy E McGraw
    Distinct phosphorylations of Akt determine the regulation of glucose uptake into fat and epithelial cells, revealing unexpected specialization in both Akt activation and its downstream control of glucose metabolism.

    Niemann-Pick type C proteins promote microautophagy by expanding raft-like membrane domains in the yeast vacuole

    Takuma Tsuji, Megumi Fujimoto ... Toyoshi Fujimoto
    Sterol transport by Niemann-Pick type C proteins induces the expansion of raft-like domains in the yeast vacuole, enabling engulfment of lipid droplets by microautophagy.

    A bioactive peptide amidating enzyme is required for ciliogenesis

    Dhivya Kumar, Daniela Strenkert ... Betty A Eipper
    Analysis of Chlamydomonas, planaria and mice reveals a novel and unanticipated role for a peptide amidating enzyme in primary and motile ciliary assembly through effects on post-Golgi trafficking.

    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    Multiple short windows of calcium-dependent protein kinase 4 activity coordinate distinct cell cycle events during Plasmodium gametogenesis

    Hanwei Fang, Natacha Klages ... Mathieu Brochet
    CDPK4 is a pleiotropic regulator controlling initiation of DNA replication, mitotic spindle assembly and flagellar activation during the early stages of Plasmodium transmission.

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

    Brittany M Edens, Jianhua Yan ... Yongchao C Ma
    A novel ALS-associated variant in UBQLN4 impairs proteasome function and beta-catenin degradation to drive aberrant axon morphogenesis in motor neurons.

    Metaphase chromosome structure is dynamically maintained by condensin I-directed DNA (de)catenation

    Ewa Piskadlo, Alexandra Tavares, Raquel A Oliveira
    Condensin I maintains chromosome organization throughout metaphase by preventing erroneous topoisomerase II-dependent sister chromatid re-entanglements.
