ESCRT-III Machinery in Membrane Dynamics and Cellular Processes
Summary
The ESCRT-III complex constitutes a central membrane-remodelling machine that shapes and severs lipid bilayers from the cytosolic face. It assembles as filaments of charged multivesicular body protein (CHMP) subunits that spiral into conical or helical structures to drive inward membrane budding. Disassembly is powered by the AAA-ATPase Vps4, which remodels and recycles ESCRT-III subunits. This modular machinery underpins diverse processes including intraluminal vesicle (ILV) biogenesis, viral egress, cytokinetic abscission and plasma membrane repair. Recent structural and live-cell studies have revealed a choreography of sequential polymer assembly, Vps4-mediated remodelling and coordinated interactions with actin and adaptor proteins. Dysregulation of ESCRT-III pathways is implicated in tumour progression, neurodegeneration and viral pathogenesis, making the complex a target for therapeutic intervention and biomolecular engineering.
Research from Nature Portfolio
Recent studies have clarified how actin and ESCRT-III cooperate during the final stage of cell division. One report demonstrates that a transient pool of branched F-actin at the tip of an ESCRT-III cone is dismantled by Cofilin-1 prior to microtubule severing by spastin, separating cytoskeletal remodelling from membrane scission. This work highlights a two-step mechanism in cytokinetic abscission, whereby actin removal confines ESCRT-III elongation to stabilise spastin recruitment while leaving membrane severing to a subsequent stage. In a complementary direction, high-resolution live-cell imaging has revealed that ESCRT-III and its ATPase partner assemble in rapid, repetitive waves on endosomal membranes. Coupled waves of clathrin recruitment ensure defined ILV size and cargo sorting, linking early coat dynamics to downstream ESCRT-III-driven scission events.

Technical terms
ESCRT-III: A subcomplex of the endosomal sorting complex required for transport that polymerises into filaments to mediate membrane deformation and scission.
Vps4: An ATPase that disassembles ESCRT-III filaments and recycles subunits through ATP-driven conformational changes.
Multivesicular body: A late endosomal compartment containing multiple intraluminal vesicles formed by ESCRT complexes.
Intraluminal vesicle (ILV): A small vesicle generated within endosomes by inward budding of the limiting membrane, typically destined for lysosomal degradation.
Cytokinetic abscission: The final separation event in cell division where the intercellular bridge is severed by ESCRT-III and associated factors.
Exosome: A type of extracellular vesicle formed as ILVs in multivesicular bodies and released upon fusion with the plasma membrane.
