The total intracellular concentration of calmodulin (CaM) in the cell appears to be significantly below the total concentration of its targets, making it a limiting factor in their regulation. In this review we discuss the ways in which this is likely to impact signaling. A key conclusion is that competition for a limiting pool of CaM enables cross-talk between CaM-dependent signaling pathways.
