title: Don't shoot the (second) messenger: endomembrane transporters and binding proteins modulate cytosolic Ca2+ levels.
abstract: Ca(2+) signal transduction requires the meticulous regulation of cytosolic Ca(2+) levels. Endomembrane Ca(2+) transporters and binding proteins are important components in partitioning these Ca(2+) signals to mediate cellular activity. Recently, many of these proteins have been characterized and mutant analysis suggests that these transporters form a network. Future attempts to manipulate plant Ca(2+) signaling must address all aspects of this complex.
