That eventually causes the muscle to move. The ACTN3 gene — also known as the “ speed gene ”— plays an important role in the actin and myosin contraction of muscle fibers.

As expected, PP1c was translocated to the cell membrane upon blue light illumination being exposed upon the OptoMYPT expressing cells, and consequently, actin and myosin-mediated contractile force ...
