Event details

Intracellular transport along microtubules is bidirectional because molecular motors of different types may move in opposite directions on the filament. Models taking into account the mutual exclusion of particles turn out to be unrealistically inefficient on static networks due to jam formation. Different mechanisms will be discussed, which lead to a more efficient bidirectional transport. In particular we propose that the dynamics of the filaments is a crucial ingredient to understand how nature makes bidirectional transport efficient.
