The shortening of muscle fiber occurs due to sliding of actin
filaments on myosin filament.
However, there are four muscle proteins involved in the process: -
Actin, Myosin, Tropomyosin, and troponin.
Myosin is the protein that constitutes the thick filaments. Myosin of
skeletal muscle is myosin-II.
Myosin participates in the contractile mechanism and also acts as an
