    plays important roles in many essential cell biological processes. Actin exists as a monomer called G-actin and as a filament called F-actin‚ a linear chain of G-actin subunits (2). Two F-actin filaments intertwine to form a microfilament‚ one of the three major components of cytoskeleton (2). Microfilament is important for generating cell movement. One mechanism involves the assembly and disassembly of microfilaments (actin dynamics) that drives biological processes‚ such as cell division‚ cell mobility
