Caption: Biophysicists of the Technische Universitaet Muenchen and the Ludwig Maximillians Universitaet Muenchen have discovered why some of these transporters can, like cars on a multi-lane motorway, change lanes: The heads of one kinesin (red) have a longer range than the other (blue) which allows "lane change" between the individual fibers (protofilaments) of the microtubule and results in a spiraling movement of the motor on the microtubule. A shorter range of the heads results in a straight movement of the motor.
