Troponin is a protein, associated with actin and tropomyosin, that binds and initiates the movement of tropomyosin on actin to allow the myosin cross-bridge to touch actin and initiate contraction.
Troponin is associated with the thin filaments and can bind to the actin molecules. There is usually one troponin per 6-8 actin molecules.
