    ESCRTs function directly on the lysosome membrane to downregulate ubiquitinated lysosomal membrane proteins

    Lu Zhu, Jeff R Jorgensen ... Scott D Emr
    The lysosome membrane is a new functional location for the ESCRTs in yeast.

    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.

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

    Naonobu Fujita, Wilson Huang ... Amy A Kiger
    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.

    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.

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

    Braden T Lobingier, Daniel P Nickerson ... Alexey J Merz
    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.

    Rab12 is a regulator of LRRK2 and its activation by damaged lysosomes

    Xiang Wang, Vitaliy V Bondar ... Anastasia G Henry
    Rab12 was identified as a key modulator of LRRK2-dependent Rab phosphorylation that mediates the recruitment of LRRK2 to lysosomes in response to damage.

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

    Jason Karch, Tobias G Schips ... Jeffery D Molkentin
    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.

    The SARS-CoV-2 accessory protein Orf3a is not an ion channel, but does interact with trafficking proteins

    Alexandria N Miller, Patrick R Houlihan ... David E Clapham
    SARS coronaviruses encode several mysterious proteins such as Orf3a and, in contrast to what has been claimed, Orf3a is not an ion channel but rather disrupts cellular trafficking by binding to the protein sorting complex known as HOPS.

    Cellular entry and uncoating of naked and quasi-enveloped human hepatoviruses

    Efraín E Rivera-Serrano, Olga González-López ... Stanley M Lemon
    Quasi-enveloped hepatitis A virions undergo clathrin-mediated endocytosis, followed by ALIX-dependent trafficking to lysosomes where the quasi-envelope is degraded, triggering uncoating of the RNA genome in association with lysosomal membrane rupture.
