    The ER–Golgi intermediate compartment is a key membrane source for the LC3 lipidation step of autophagosome biogenesis

    Liang Ge, David Melville ... Randy Schekman
    A cell-free biochemical assay for protein lipidation identifies the ER–Golgi intermediate compartment as a key early station in the formation of an autophagosome.

    Mitochondrial Rab GAPs govern autophagosome biogenesis during mitophagy

    Koji Yamano, Adam I Fogel ... Richard J Youle
    Two GAP proteins bound to mitochondria regulate the enyzme Rab7, and thereby the expansion of the isolation membrane during mitophagy, downstream of PINK1 and Parkin, two proteins that are mutated in familial Parkinson's disease.

    Phosphatidylinositol 3-kinase and COPII generate LC3 lipidation vesicles from the ER-Golgi intermediate compartment

    Liang Ge, Min Zhang, Randy Schekman
    Building on previous work (Ge et al., 2013), it is shown that the ER-Golgi intermediate compartment is a platform for the production of COPII vesicles as precursor membranes for the lipidation of LC3, which is an essential step in autophagosome biogenesis.

    Architecture and dynamics of the autophagic phosphatidylinositol 3-kinase complex

    Sulochanadevi Baskaran, Lars-Anders Carlson ... James H Hurley
    The first three-dimensional structure of the PI3KC3 complex I, which is involved in autophagy, provides a framework for understanding the allosteric regulation of lipid kinase activity.

    The GTPase Rab26 links synaptic vesicles to the autophagy pathway

    Beyenech Binotti, Nathan J Pavlos ... Reinhard Jahn
    Rab26 selectively directs synaptic and secretory vesicles into preautophagosomal structures, suggesting the presence of a novel pathway (vesiculophagy) for degradation of synaptic vesicles.

    VCP-dependent muscle degeneration is linked to defects in a dynamic tubular lysosomal network in vivo

    Alyssa E Johnson, Huidy Shu ... Graeme W Davis
    The AAA-ATPase VCP sustains sarcoplasmic proteostasis, in part, by controlling autophagosome-lysosome fusion and the integrity of a dynamic tubular lysosomal network.

    Ferritinophagy via NCOA4 is required for erythropoiesis and is regulated by iron dependent HERC2-mediated proteolysis

    Joseph D Mancias, Laura Pontano Vaites ... J Wade Harper
    NCOA4, the ferritin autophagy receptor, is regulated by HERC2 in an iron-dependent manner and is critical for red blood cell development.

    Oligomerization of p62 allows for selection of ubiquitinated cargo and isolation membrane during selective autophagy

    Bettina Wurzer, Gabriele Zaffagnini ... Sascha Martens
    Oligomerization of p62/SQSTM1 generates high avidity binding regions that enable it to spatially select for concentrated ubiquitin and ATG8-family proteins.

    Translocation of interleukin-1β into a vesicle intermediate in autophagy-mediated secretion

    Min Zhang, Samuel J Kenny ... Randy Schekman
    Reconstitution of interleukin-1β secretion in non-macrophage cells implicates how this pro-inflammatory cytokine enters into the unconventional pathway of secretion through autophagy.

    Intracellular sphingosine releases calcium from lysosomes

    Doris Höglinger, Per Haberkant ... Carsten Schultz
    Sphingosine acts as a lipid messenger molecule in intracellular signaling networks that are relevant to lysosomal function and Niemann-Pick disease.
