'''Myosin''' is comprised of many different classes of motor proteins, and is universal in all eukaryotic cells.<ref name="Varkuti">PMID: 22343723</ref> Myosin II is the more well known form of myosin that is involved in muscle contractions; it acts in complex with [[actin]] to create a powerstroke and cause muscular contraction and relaxation.<ref name="Ruppel">PMID: 8862525</ref> Myosin is the contractile unit of a sarcomere. Repeating units of sarcomeres make up a myofibril (muscle fiber), and bundles of fibers make up a skeletal muscle. The figure below (right) is a proteolytic fragment of myosin generated by papain digestion in ''Gallus gallus'' (chicken). | '''Myosin''' is comprised of many different classes of motor proteins, and is universal in all eukaryotic cells.<ref name="Varkuti">PMID: 22343723</ref> Myosin II is the more well known form of myosin that is involved in muscle contractions; it acts in complex with [[actin]] to create a powerstroke and cause muscular contraction and relaxation.<ref name="Ruppel">PMID: 8862525</ref> Myosin is the contractile unit of a sarcomere.
