We propose a mechanism of sequentially exchanging filament composition to increase filament curvature and develop a kinetic model for composite filament assembly. Our study shows that this sequential polymer assembly mechanism reduces the energetic barrier for membrane deformation.
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.
