WebThe cytoskeleton (literally, “cell skeleton”) is a network of filaments that supports the plasma membrane, gives the cell an overall shape, aids in the correct positioning of organelles, provides tracks for the transport of vesicles, and (in many cell types) allows the cell to move. WebSummary. Myosin is a contractile protein found in the muscles of animals as well as non-muscle cells. It is responsible for muscle contraction as well as intracellular transport. Myosin is made of six subunits including two heavy chains and four light chains. The molecule is considered to be made up of three domains.
