WebThe myofilaments are composed of several different proteins, constituting about 50 percent of the total protein in muscle. The other 50 percent consists of the proteins in the Z line … The protein complex composed of actin and myosin, contractile proteins, is sometimes referred to as actomyosin. In striated skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length in the order of a few micrometers, far less than the length of the elongated muscle cell (up to several centimeters in some skeletal muscle cells). The contractile nature of this protein complex is based on the structure of the thick and thin filaments. The thic… WebA myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle. Half of the myosin heads angle to the left and half of them angle to the right, creating an area in the middle of the filament known as the M-region or bare zone.
