36) Furthermore, the myosin head could consistently interact with actin without moving away from the actin filament because it was firmly affixed to a large scanning probe thus preventing diffusion.
The whole system thus returns to the rest state with the active troponin I and myosin ATPase by blocking active sites on actin filament.
sup][13] As a protein that affects the dynamics of the actin cytoskeleton via stabilization of actin filaments, transgelin is both directly and indirectly involved in many processes such as migration, proliferation, differentiation, and apoptosis.

Morphogenetic movements include gastrulation, convergent extension of notochord cells, and neurulation, and these morphogenetic movements share two features: the actin filament has important roles and the small GTPase Rho mediates F-actin formation.
Cells treated for 24 hr with 10-6 M FL (Figure 2B), however, contained no visible stress fibers, but rather exhibited shortened and disorganized actin filaments.
Here we will focus on how the underlying actin filament bundle regulates filopodium growth and retraction cycles at the micrometer and seconds scales.
