Five proteins found on myofilaments
WebMyofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thick, thin, and elastic myofilaments, which repeat along the length … WebAt 40-nm intervals along the thin myofilaments, tropomyosin molecules are attached to troponin complexes. In the troponin complexes, there are three proteins: troponin I, troponin T, and troponin C. Troponin I anchors the complex to the thin myofilament; troponin T attaches to the tropomyosin molecules, and troponin C binds calcium.

WebDesmin filaments appear to be anchored to the sarcolemma by a number of adhesion proteins such as vinculin. At myotendinous junctions, the thin myofilaments of the last sarcomere attach to the sarcolemma, which is thrown into numerous villous projections. The thin myofilaments are anchored by the proteins α-actinin and vinculin, among others.
