Caption: Differential regulation of dynein and kinesin motor proteins by the microtubule associated protein tau. The Penn group found that dynein, which carries loads towards the interior of the nerve cell, maneuvers around tau; whereas, kinesin, which carries loads towards the outside of the nerve cell, detaches when it encounters tau.
