21. Rigor mortis says the myosin heads break down . . . somehow. 22. This flow of ions kick-starts the contractile proteins actin and myosin . 23. Filaments near the cell's end interact with myosin which causes contraction. 24. Myosin filaments have club-shaped heads that project toward the actin filaments.25. Thick filaments are made of the elongated protein myosin . 26. The plants implanted with human myosin Vb do not exhibit continuous cytoplasmic streaming. 27. The myosin ceases binding to the thin filament, and the muscle relaxes. 28. In all other neurites however, the actin filaments are stabilized by myosin . 29. The encoded protein binds calcium and is activated by myosin light chain kinase. 30. Aurora B also phosphorylates myosin II regulatory light chain at the cleavage furrow.
