UniProt Comments
Involved in the regulatory pathway for the control of intracellular Na+ and K+ homeostasis and salt tolerance. Activates the vacuolar H+/Ca2+ antiporter CAX1 and operates in synergy with CBL4/SOS3 to activate the plasma membrane Na+/H+ antiporter SOS1. CIPK serine-threonine protein kinases interact with CBL proteins. Binding of a CBL protein to the regulatory NAF domain of CIPK protein lead to the activation of the kinase in a calcium-dependent manner. Phosphorylates CBL1, CBL4 and CBL10.
