Polymerization forces of interacting filaments — •Jaroslaw Krawczyk and Jan Kierfeld — TU Dortmund, Fakultät Physik, 44221 Dortmund

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 an attractive interaction between filaments on the polymerization dynamics. We find that the force-velocity characteristics, the stall force and maximal growth velocity of the filament assembly depend sensitively on the presence of interactions.
