WebAug 5, 2024 · The thick filaments are composed of myosin, and the thin filaments are predominantly actin, along with two other muscle proteins, tropomyosin and troponin. How do myofilaments slide together? The molecular mechanism whereby myosin and acting myofilaments slide over each other is termed the cross-bridge cycle. WebThick filaments occur only in the A band of a myofibril. Thin filaments attach to a protein in the Z disc called alpha-actinin and occur across the entire length of the I band and partway into the A band. The region at which thick and thin filaments overlap has a dense appearance, as there is little space between the filaments.
