Thin myofilaments are made up of the protein

WebMyofilaments are the actual proteins involved in muscle contraction. These myofilaments may be either thick filaments, made of protein molecules called myosin, or thin filaments, made of a helix of proteins called actin. Individual myofilaments of myosin and actin do not extend the length of a muscle cell like the larger myofibrils do. WebThin myofilaments are a polymer of actin with firmly bound executive proteins troponin and tropomyosin. At the point when the cytoplasmic Ca2+ focus is low, troponin and tropomyosin repress the actin-enacted adenosine triphosphatase (ATPase) of myosin.[46]
