Possible models for the bi-directional movement
observed in the dynein-dynactin molecular motor along microtubules.
movements may be due to random, diffusive motions; B) Some of the
movements may be due to a flexible rotation of the dynein ring;
and C) Some of the movement may be dictated by the microtubule lattice
