WebThree superfamilies of motor proteins power directed movements on microtubules or actin filaments. Myosin motors move on actin filaments, whereas kinesin and dynein motors … Motor 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 … See more Motor proteins are a class of molecular motors that can move along the cytoplasm of cells. They convert chemical energy into mechanical work by the hydrolysis of ATP. Flagellar rotation, however, is powered by a proton pump See more Motor proteins are the driving force behind most active transport of proteins and vesicles in the cytoplasm.
