WebMar 16, 2024 · This review introduces the sarcomere proteins involved in striated muscle contraction and places greater emphasis on the more recently identified and less well-characterized myofilaments: cardiac myosin binding protein-C, titin, nebulin, and obscurin. © 2024 American Physiological Society. Compr Physiol 7:675-692, 2024. WebMyofilaments are protein fibers consisting of thick ( myosin) and thin ( actin) filaments and are responsible for the contractile properties of muscle cells. Actin myofilaments ( thin filaments) [1] Actin myofilaments are thin filaments composed of actin molecules, regulatory proteins, and nebulin.
