The roles of calcium in cell signaling consequent to chromatophorotropin action and as an activator of mechanochemical transport proteins responsible for pigment granule translocation were investigated in the red ovarian chromatosomes of the freshwater shrimp Macrobrachium olfersii. Chromatosomes were perfused with known concentrations of free Ca++ (10(-3) to 10(-9) M) prepared in Mg(++)-EGTA-buffered physiological saline after selectively permeabilizing with 25 microM calcium ionophore A23187… CONTINUE READING
