Abstract

Store-operated Ca2+ entry is a process whereby the depletion of intracellular Ca2+ stores signals the opening of plasma membrane Ca2+ channels. It has long been thought that the main function of store-operated Ca2+ entry was the replenishment of intracellular Ca2+ stores following their discharge during intracellular Ca2+ signaling. Recent results, however, suggest that the primary function of these channels may be to provide direct Ca2+ signals to recipients localized to spatially restricted areas close to the sites of Ca2+ entry in order to initiate specific signaling pathways.
