41. PKC? binds myosin light chain-2 exhibited changes in post-translational modifications. 42. This prevents actin-myosin cross-bridging and effectively shuts off muscle contraction. 43. Approximately 300 myosin molecules constitute one thick filament. 44. In these cells the myosin -1a protein localizes specifically to the brush border. 45. This is hypothesized to occur via the binding of calcium to the myosin motor. 46. The gene encodes a subunit of myosin phosphatase. 47. This myosin is also found in the ciliated protozoan " Tetrahymena thermaphila ". 48. The binding of the myosin heads to the muscle actin is a highly regulated process. 49. Telokin may play a role in the stabilization of unphosphorylated smooth-muscle myosin filaments. 50. Biological materials such as collagen, microtubules, and muscle myosin can produce SHG signals.
