WebJun 6, 2011 · The main component of the transition from G- to F-actin is a 12°--13° propeller-like rotation of the outer domain with respect to the inner domain about an axis roughly at right angle to the helix axis (Figure 3). Moreover, there are bending movements of domains 2 and 4 in the same direction. The final result is that F-actin is flatter than G ... WebF-actin and is an important aspect of cellular injury in tissue ischemia. We propose that this conversion results from altering the ratio of ATP-G-actin and ADP-G-actin, causing a net decrease in the concentration of thymosin-actin complexes as a consequence of the differential affinity of thymosin 4 for ATP- and ADP-G-actin.
