The plant SOS2 family of protein kinases and their interacting activators, the SOS3 family of calcium-binding proteins, function together in decoding calcium signals elicited by different environmental stimuli. SOS2 is activated by Ca-SOS3 and subsequently phosphorylates the ion transporter SOS1 to bring about cellular ion homeostasis under salt stress. In addition to possessing the kinase activity, members of the SOS2 family of protein kinases can bind to protein phosphatase 2Cs. The crystal structure of the binary complex of Ca-SOS3 with the C-terminal regulatory moiety of SOS2 resolves central questions regarding the dual function of SOS2 as a kinase and a phosphatase-binding protein.
