Influence of filament positioning on polymerization of filament ensembles — •Jarosław Krawczyk and Jan Kierfeld — Technische Universität Dortmund, Lehrstuhl für Theoretische Physik I,

Many cellular processes are driven by polymerization of filamentous proteins. Using stochastic simulations based on the Gillespie algorithm we investigate force-generation by polymerizing groups of filaments or protofilaments and study the influence of the relative starting positions of filaments on the dynamics of growing speed. We find a strong influence of the starting position on the growth velocity. While the growth velocity for different starting configurations differ, the stall force remains unchanged.
