Calmodulin Binds RalA and RalB and Is Required for the Thrombin-induced Activation of Ral in Human Platelets

Ral GTPases may be involved in calcium/calmodulin-mediated intracellular signaling pathways. RalA and RalB are activated by calcium, and RalA binds calmodulin in vitro . It was examined whether RalA can bind calmodulin in vivo , whether RalB can bind calmodulin, and whether calmodulin is functionall...
