1. The gelation of F-actin was evoked by adding an appropriate amount of α-actinin. Larger amounts of a-actinin co-precipitated F-actin. It is concluded that ‘gel-actin’ is a complex of F-actin and α-actinin.
2. Polymerization rate of G-actin was accelerated by a-actinin when observed with viscometry or with flow birefringence.
3. Effects of α-actinin alone or with β-actinin on the birefringent properties of F-actin are described.
4. Correlation between the effects of α-actinin on the physical properties of actin and its effect on superprecipitation is discussed.
