There are three different types of myofilaments: thick, thin, and elastic filaments. Thick filaments consist primarily of a type of myosin, a motor protein – myosin II. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a … See more Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The … See more The protein complex composed of actin and myosin, contractile proteins, is sometimes referred to as actomyosin.
