we suggest that the 95,000-dalton protein contributes to modulation of the consistency and contractility of the cytoplasm of d. discoideum amoebae , since it could cross-link actin filaments in vitro in a reversible process that was regulated by changes in the concentration of calcium and of protons , and since it was present in large quantity in the cytoplasm of these cells .
