Motor Proteins
Motor Proteins are proteins which use chemical energy from adenosine triphosphate (ATP) to generate mechanical force, allowing for movement within cells. These proteins act as 'motors' that serve important roles in cells, such as the movement of organelles in cytoplasm, transport of molecules through the cell membrane and contraction of the cytoskeleton. Specifically, Motor Proteins are responsible for the motor functions in microtubules and actin filaments. Consequently, they play an important role in cellular movement, signaling and reproduction. In general, Motor Proteins contribute to the function and maintenance of cells which is essential for the proper functioning of the entire organism.
