WebMotor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrate: microfilaments or microtubules. Actin motors such as myosin move along microfilaments through interaction with actin, and microtubule motors such as dynein and kinesin move along microtubules through interaction with tubulin. WebThe cellular cytoskeleton enables an active delivery of components by providing the ‘tracks’ on which molecular motors can walk. Both the microtubules and microfilaments have specific motor proteins that walk along them. Myosins, for example, walk on microfilaments while dynein and kinesin walk on microtubules.
