The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.

No biological system has been studied by more diverse approaches than the actin-based molecular motor myosin. Biophysics, biochemistry, physiology, classical genetics and molecular genetics have ...

There are three classes of cytoskeletal motor proteins: myosins, kinesins and dyneins. Myosins move along actin filaments, and kinesins and dyneins move along microtubules. Kinesins (with the ...

Each cylindrical tube is filled with parallel rods of actin filaments bundled by cross-linking proteins. Filamentous actin is a chemical motor; the energy released upon synthesis and breakdown of ...
