Evidence for differential intracellular localization of the Acanthamoeba myosin isoenzymes. 
The three myosin isoenzymes of Acanthamoeba castellanii coexist within a single cell and the native molecules probably have the same unusual polypeptides composition as the isolated enzymes.  The two myosin I isoenzymes seem to be preferentially localized near the plasma membrane while myosin II seems to be much less concentrated near the plasma membrane than elsewhere in the cytoplasm.
