Don't shoot the (second) messenger: endomembrane transporters and binding proteins modulate cytosolic Ca2+ levels

Curr Opin Plant Biol. 2003 Jun;6(3):257-62. doi: 10.1016/s1369-5266(03)00036-0.

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.
