Abstract
In the unicellular green alga Eremosphaera viridis caffeine induces oscilla tions of cytosolic Ca2+ which cause membrane potential oscillations. Applic ation of the caffeine analogues isocaffeine, theophylline, and isotheophyll ine resulted in membrane potential oscillations with a structure-activity r elationship comparable to isolated ryanodine/cyclic ADPribose (cADPR) recep tor Ca2+ channels from animal cells.
