Chief protein in muscle and the main constituent of the thick filaments of muscle fibers. In conjunction with actin, it is responsible for the contraction and relaxation of muscles.
One of the chief proteins of muscle.
Muscle cell protein that (with actin) plays a role in muscle contraction and relaxation.
Along with actin, myosin is one of the two principal contractile proteins in the muscle cell.
Protein in muscle that, along with actin, makes up the contractile elements of muscles.
The most abundant protein in muscle fibrils, having the important properties of elasticity and contractility. With actin, it comprises the principal contractile element of muscles.
A protein present in muscle fibrils and constituting about 45% of total muscle protein. It consists of long chains of polypeptides joined to each other by side chains. Myosin and actin are the contractile proteins in muscle fibers. Myosin also is an enzyme that catalyzes the removal of the third phosphate from ATP, thereby releasing the energy needed for contraction.
A significant protein constituent of muscle fibers, myosin, in conjunction with actin, forms the basis for muscle contraction. Myosin molecules move along actin filaments, facilitating the shortening of muscle fibers.
