The effect of ionomycin on calcium fluxes in sarcoplasmic reticulum vesicles and liposomes

Ionomycin, a recently discovered calcium ionophore, inhibits the ATP-dependent active Ca2+ transport of rabbit sarcoplasmic reticulum vesicles at concentrations as low as 10(-8) to 10(-6) M. The effect is due to an increase in the Ca2+ permeability of the membrane which is also observed on liposomes...
