    Lysosomal membrane glycoproteins bind cholesterol and contribute to lysosomal cholesterol export

    Jian Li, Suzanne R Pfeffer
    LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.

    Continuous transport of a small fraction of plasma membrane cholesterol to endoplasmic reticulum regulates total cellular cholesterol

    Rodney Elwood Infante, Arun Radhakrishnan
    A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.

    Autophagic cell death is dependent on lysosomal membrane permeability through Bax and Bak

    Jason Karch et al.
    Molecular pathways controlling autophagic cell death are regulated at the level of the lysosome through the activity of the pro-death Bcl-2 family member Bax/Bak.

    Identification of a transporter complex responsible for the cytosolic entry of nitrogen-containing bisphosphonates

    Zhou Yu et al.
    Identification of a transporter complex comprised of SLC37A3 and ATRAID is required for nitrogen-containing bisphosphonates to enter the cytosol from lysosomes and exert their therapeutic effects on bone.

    PI(3,5)P2 biosynthesis regulates oligodendrocyte differentiation by intrinsic and extrinsic mechanisms

    Yevgeniya A Mironova et al.
    The signaling lipid PI(3,5)P2 supports the formation of the myelin sheath, by regulating trafficking of myelin building blocks within oligodendrocytes and communication between oligodendrocytes and neuronal axons.

    SM proteins Sly1 and Vps33 co-assemble with Sec17 and SNARE complexes to oppose SNARE disassembly by Sec18

    Braden T Lobingier et al.
    Sec1/Munc18 (SM) proteins shield SNARE complexes from NSF/Sec18-mediated disassembly through cooperative binding interactions with SNARE complexes and the universal co-chaperone α-SNAP/Sec17.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.
