Kinesins and Dyneins
Kinesins are motor proteins that move along microtubule filaments. Kinesins are powered by ATP hydrolysis. Kinesins walk toward the positive end of the microtubule (from the center of the cell towards the periphery). Dynein is also a motor protein that is powered by ATP. However, Dynein walks towards the negative end of the microtubule.
