The thin filaments of a muscle fibre are made up of actin, troponin and tropomyosin. One thin filament probably contains 300-400 actin molecules, about 50 tropomyosin and 50 troponin. It is said that tropomyosin plays a vital role in sensitizing the contractile proteins (actin and myosin) to calcium ions.
