| Abstract: | In the unicellular green alga Eremosphaera viridis caffeineinduces oscillations of cytosolic Ca2+ which cause membranepotential oscillations. Application of the caffeine analoguesisocaffeine, theophylline, and isotheophylline resulted in membranepotential oscillations with a structure-activity relationshipcomparable to isolated ryanodine/cyclic ADPribose (cADPR) receptorCa2+ channels from animal cells.
