was purified as an activity present in stimulated Dictyostelium
but not in unstimulated amoeba that nucleated actin polymerization in an
attempt to understand how the nucleation is controlled. It later
turned out that aginactin was actually a complex of Hsc70 and Capping
protein (Cap32/34) (Eddy
et al, 1992; 1993)
et al. (1992).
