Title: Transverse fluctuations control the assembly of semiflexible filaments
(Submitted on 6 Mar 2023 (v1), last revised 31 Oct 2023 (this version, v2))
Abstract: The kinetics of the assembly of semiflexible filaments through end-to-end annealing is key to the structure of the cytoskeleton, but is not understood. We analyze this problem through scaling theory and simulations, and uncover a regime where filaments ends find each other through bending fluctuations without the need for the whole filament to diffuse. This results in a very substantial speed-up of assembly in physiological regimes, and could help understand the dynamics of actin and intermediate filaments in biological processes such as wound healing and cell division.
