Role of the Dictyostelium 30 kDa protein in actin bundle formation.


We have studied the formation of bundles in mixtures of actin with the Dictyostelium 30 kDa actin-bundling protein as a function of 30 kDa protein concentration, actin concentration, and filament length. The presence of the 30 kDa protein promotes formation of filament bundles at actin concentrations and filament lengths that are not spontaneously aligned… (More)
