  text: The sequential exchange of filament composition to increase filament curvature
    was proposed as a mechanism for how some biological polymers deform and cut membranes.
    The relationship between the filament composition and its mechanical effect is
    lacking. We develop a kinetic model for the assembly of composite filaments that
    includes protein–membrane adhesion, filament mechanics and membrane mechanics.
    We identify the physical conditions for such a membrane remodeling and show this
    mechanism of sequential polymer assembly lowers the energetic barrier for membrane
    deformation.

  text: ESCRT-III filaments are composite cytoskeletal polymers that can constrict
    and cut cell membranes from the inside of the membrane neck. Membrane-bound ESCRT-III
    filaments undergo a series of dramatic composition and geometry changes in the
    presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the
    membrane morphology. We set out to understand the physical mechanisms involved
    in translating the changes in ESCRT-III polymer composition into membrane deformation.
    We have built a coarse-grained model in which ESCRT-III polymers of different
    geometries and mechanical properties are allowed to copolymerise and bind to a
    deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific
    polymers, we identify mechanical regimes in which changes in filament composition
    trigger the associated membrane transition from a flat to a buckled state, and
    then to a tubule state that eventually undergoes scission to release a small cargo-loaded
    vesicle. We then characterise how the location and kinetics of polymer loss affects
    the extent of membrane deformation and the efficiency of membrane neck scission.
    Our results identify the near-minimal mechanical conditions for the operation
    of shape-shifting composite polymers that sever membrane necks.
