The cytoskeleton is made up of three kinds of protein filaments: Actin filaments (also called microfilaments); Intermediate filaments and; Microtubules.
Myofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thick and thin filaments called myofilaments, which repeat along the length of the myofibril in sections called sarcomeres. Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. 2  Actin, when polymerized into filaments, forms the ladder along which the myosin filaments climb to generate motion. 3  Thick filaments consist primarily of the protein myosin, held in place by titin filaments.
