11. Engulfment of material is facilitated by the actin-myosin contractile system. 12. The myosin heads now return to their upright relaxed position. 13. The binding of a new ATP molecule will release myosin from actin. 14. The unconventional myosins also have divergent tail domains, suggesting unique functions. 15. For example, the human genome contains over 40 different myosin genes. 16. The action of myosin attachment and actin movement results in sarcomere shortening. 17. Activated ROCK1 phosphorylates MLC involved in actin-myosin contractility. 18. When myosin phosphatase binds to myosin, it removes the phosphate group. 19. When myosin phosphatase binds to myosin , it removes the phosphate group. 20. His research is focused on studying molecular motors particularly myosin .
