Model of the placement of GRIK kinases at the interface between sensing of the energy status and salinity stress signalling.

Salt stress induces the activation of SOS2 through calcium/CBL (SOS3 and SCaBP8) binding. Sugar/energy status is transmitted through SOS2 phosphorylation by GRIK1/2, which also controls reciprocally the activity of SnRK1s.
