Actin
Actin is a protein important for cell movements. It is expressed in all body cells, but especially in muscle cells. Actin can polymerize into microfilament, which are essential for the cytoskeleton, for cell motility, and for contraction of the cell during cell division.
Together with myosin filaments, actin provides the mechanism for muscle contraction, utilizing energy from ATP.
