Receptor-induced Ca(2+) oscillations provide 'digitized' signals that confer precise activation of downstream targets. New studies reveal that STIM proteins - sensors of endoplasmic reticulum Ca(2+) levels - cyclically translocate during oscillations, transiently coupling to activate cell-surface Call entry channels, resulting in a spatially unique signal that selectively triggers immediate-early gene expression.
