Motor proteins are a category of proteins that convert chemical energy into mechanical work, enabling movement within cells. They play essential roles in various cellular processes, including intracellular transport, muscle contraction, cell division, and more. Motor proteins achieve movement by interacting with the cytoskeleton, which is a network of protein filaments that provide structural support to the cell.
