Myosin
Myosin is a superfamily of motor proteins best known for their role in muscle contraction and their involvement in a wide range of other cellular processes, such as cell division, transport, and motility. Myosins convert chemical energy in the form of ATP into mechanical work, enabling them to "walk" along actin filaments. Each myosin protein consists of a head, which binds to actin and hydrolyzes ATP, and a tail, which determines the specific cargo it transports or the cellular structure it interacts with. Dysfunction in myosin activity can lead to various diseases, including muscle disorders, heart conditions, and certain types of deafness, making myosins a vital target for medical research and therapeutic intervention.
