    Electrostatic lateral interactions drive ESCRT-III heteropolymer assembly

    Sudeep Banjade et al.
    ESCRT-III heteropolymers utilize non-specific lateral electrostatic interactions to recognize one another, which may enable the polymers to slide along one another and adapt to different curvatures.

    ESCRT-III activation by parallel action of ESCRT-I/II and ESCRT-0/Bro1 during MVB biogenesis

    Shaogeng Tang et al.
    Building on previous work (Tang et al., 2015), novel ESCRT-III subunit Snf7 auto-activation mutants are used to reveal two parallel ubiquitin-dependent pathways during multivesicular endosome biogenesis.

    Recruitment dynamics of ESCRT-III and Vps4 to endosomes and implications for reverse membrane budding

    Manuel Alonso Y Adell et al.
    Quantitative 3D lattice light sheet microscopy of unperturbed cells combined with electron tomography and acute loss of function experiments reveals how dynamic ESCRT-III/Vps4 assemblies succeed in reverse membrane budding on endosomes.

    ULK3 regulates cytokinetic abscission by phosphorylating ESCRT-III proteins

    Anna Caballe et al.
    ULK3 is a kinase in the abscission checkpoint that temporarily inactivates ESCRT-III proteins via phosphorylation, which is required to delay cytokinesis in response to defects in mitosis.

    ESCRT-III drives the final stages of CUPS maturation for unconventional protein secretion

    Amy J Curwin et al.
    The release of Acb1 protein from yeast cells requires the ESCRT-III complex to stabilize the compartment for unconventional protein secretion (CUPS).

    Structure of cellular ESCRT-III spirals and their relationship to HIV budding

    Anil G Cashikar et al.
    Electron microscopy on native membranes reveals the shape and potential function of protein machinery responsible for budding vesicles and viruses away from the cytoplasm.

    Timing of ESCRT-III protein recruitment and membrane scission during HIV-1 assembly

    Daniel S Johnson et al.
    During viral assembly, ESCRTIII and VPS4 are recruited after most of the HIV-1 membrane is bent but disappear prior to scission of the virion from the cell.

    The AAA ATPase Vps4 binds ESCRT-III substrates through a repeating array of dipeptide-binding pockets

    Han Han et al.
    A 3.2 Å resolution structure of Vps4 provides a detailed model for protein substrate binding and translocation by AAA ATPases.

    Mechanisms of virus dissemination in bone marrow of HIV-1–infected humanized BLT mice

    Mark S Ladinsky et al.
    Large-volume light microscopy combined with higher-resolution electron tomography revealed the spatial distribution of virus-producing cells and highlighted mechanisms of HIV-1 dissemination in bone marrow from a small animal model.
