Research Abstract

Myosin II forms a folded conformation (10S form) in the inactivated state; however, the physiological significance of the 10S form is still unclear. To investigate the role of 10S form, we generated a mutant of myosin II, which cannot fold into a 10S form under physiological condition. The mutant myosin II was less dynamic by stabilizing the filamentous form, and accumulated in the posterior region of migrating cells. We proposed that the 10S form is necessary for maintaining inactive nonmuscle myosin II in an unassembled state and for recruitment of nonmuscle myosin II to a specific region of the cell.
