Minimal F-actin exchange cautions against assuming rapid filament turnover in cells; leaves open regulatory mechanisms in physiological contexts.
Under physiological ionic conditions, only a small percentage of subunits in highly purified skeletal muscle or Dictyostelium F-actin participate in exchange.
Pardee et al. (1982) studied this question.
