    In vivo vizualisation of mono-ADP-ribosylation by dPARP16 upon amino-acid starvation

    Angelica Aguilera-Gomez et al.
    Amino-acid induced Sec body formation is mediated by PARP16 dependent MARylation of Sec16, a component of the endoplasmic reticulum exit site.

    The structure of the COPII transport-vesicle coat assembled on membranes

    Giulia Zanetti et al.
    A structure of the complete, membrane bound, COPII coat solved by sub-tomogram averaging reveals the arrangement of all protein subunits on the membrane and suggests a mechanism for coating heterogeneously-shaped carriers.

    Vibrator and PI4KIIIα govern neuroblast polarity by anchoring non-muscle myosin II

    Chwee Tat Koe et al.
    Vibrator and PI4KIIIα that stimulate the synthesis of PI(4)P anchor non-muscle myosin II RLC (Sqh) to the plasma membrane and conversely Sqh associates with PI(4)P and facilitates its membrane localization during asymmetric division of neuroblasts.

    Non-coding cancer driver candidates identified with a sample- and position-specific model of the somatic mutation rate

    Malene Juul et al.
    A new statistical approach identifies non-coding regulatory regions of genes as driver candidates with recurrent mutations across cancer samples that associate with gene expression, patient survival or mutational phenotype.

    Neurofibromin controls macropinocytosis and phagocytosis in Dictyostelium

    Gareth Bloomfield et al.
    Inactivation of the Dictyostelium orthologue of the tumour suppressor Neurofibromin (NF1) enables amoebae to ingest dissolved nutrients using macropinocytosis more rapidly, and to prey on larger organisms using phagocytosis.

    A stress assembly that confers cell viability by preserving ERES components during amino-acid starvation

    Margarita Zacharogianni et al.
    Amino-acid starvation leads to the formation of a reversible stress assembly, the Sec body, which is a pro-survival reservoir for components of the ER exit sites.

    Differences across cyclophilin A orthologs contribute to the host range restriction of hepatitis C virus

    Jenna M Gaska et al.
    Incompatibilities between the viral replication machinery and orthologs of the essential host factor cyclophilin A (CypA) contribute to the narrow host range of hepatitis C virus.

    SLY1 and Syntaxin 18 specify a distinct pathway for procollagen VII export from the endoplasmic reticulum

    Cristina Nogueira et al.
    A cross-linking screen finds proteins that interact with TANGO1 to export Procollagen VII, and suggests a new model for the secretion of these bulky cargoes that are involved in skin and bone formation.

    A physical mechanism of TANGO1-mediated bulky cargo export

    Ishier Raote et al.
    TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.
