Figure 4From: Continuum descriptions of cytoskeletal dynamicsSchematic representation of filament dynamics in presence of nucleation promoting factors (NPFs). a) Filaments treadmill by attachment of monomers at one end and detachment at the other. b) Filaments disassemble spontaneously. c) New filaments are generated by NPFs. d) NPFs bind to filaments. Binding is cooperative, favoring attachments in the vicinity of already bound NPFs. e) NPFs spontaneously detach from filaments.Back to article page
