31. Myosin VI is a molecular motor involved in intracellular vesicle and organelle transport.32. This results in a dramatic increase in myosin specificity. 33. The mechanism of PP1 for myosin phosphatase, with critical enzyme residues shown. 34. Stress fibers are primarily composed of actin and myosin . 35. Spudich first attempted to create an in vitro setup with actin and myosin . 36. This gene encodes a member of the myosin -binding protein C family. 37. Energy is released and stored in the myosin head to utilize for later movement. 38. Human myosin Vb only moves at a rate of . 19 microns / sec. 39. The titin protein is located between the myosin thick filament and the Z disk. 40. It is identical to the C-terminus of myosin light-chain kinase.
