title: Cellular signalling: STIMulating calcium entry.
abstract: The molecular identity of the signal coupling intracellular Ca(2+) store depletion to the activation of Ca(2+) entry has long resisted exposure. Two recent studies independently implicate the STIM protein family as essential components in this coupling. These data provide new impetus to resolve how store Ca(2+) content is sensed and communicated to store-operated Ca(2+) channels at the cell surface.
