Abstract
Muscle contraction and force regulation is thought to occur exclusively through the interaction of the contractile proteins actin and myosin and in accordance with the assumptions underlying the cross-bridge theory. Here, we demonstrate that a third protein, titin, plays a major role in muscle force regulation, particularly for eccentric contractions and at long muscle and sarcomere lengths.
