Motor Protein Traffic

Caption: This image depicts motor protein traffic along a single microtubule highway. Much like vehicular traffic in real life, kinesin motor traffic reduces the velocity of single motors. Multi-motor "cargos," such as the quantum dot depicted, can stay attached to the microtubule much longer because they can add multiple motors.
