NettetWhile kinesin and dynein motor proteins move on microtubules, myosin motor proteins move on actin filaments. Fast transport is typically microtubule-based, myosin motors move more slowly along actin. 10 There is also a spatial difference as microtubule networks span the entire cytosol while actin fibers are more (but not exclusively) …

A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases, a type of enzyme). The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport, and intraflagellar transport.
