Five proteins found on myofilaments
WebMyofilaments are organized structures in muscle cells that contain the actin and myosin. The organized globular proteins of actin in muscle cells form a thin filament, and bundles of over 200 myosin proteins form a thick filament. The thick filament myosin heads “walk” along the actin thin filaments.

Five proteins found on myofilaments
Did you know?
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 myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, … See more 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 … See more The protein complex composed of actin and myosin, contractile proteins, is sometimes referred to as actomyosin.
