title: NAADP: an atypical Ca2+-release messenger?
abstract: Recently, nicotinic acid adenine dinucleotide phosphate (NAADP) has been shown, using different techniques, to mobilize intracellular Ca2+ stores in invertebrate, lower vertebrate, plant and mammalian cells. This endogenous molecule might play an atypical role in Ca2+ signalling by coordinating the responses of other Ca2+-releasing messengers. Furthermore, radioligand binding experiments have provided an insight into how desensitization of the NAADP receptor might occur.
