Myosin II plays the most important role in cellular force generation. Myosin II molecules self-assemble into filaments with different structures depending on myosin II isoforms and other conditions ...

Non-muscle myosin 2 is a motor protein involved in many cellular processes, most notably cell motility and contraction, which allows a cell to crawl and reorganize organelles within itself.

Figure 2: Prestroke and poststroke states of subfragment 1. The conformation of myosin V when strongly bound to actin has been revealed by electron microscopy 39. The authors point out that ...
