The Arabidopsis AtPP2CA Protein Phosphatase Inhibits the GORK K(+) Efflux Channel and Exerts a Dominant Suppressive Effect on Phosphomimetic-activating Mutations

The regulation of the GORK (Guard Cell Outward Rectifying) Shaker channel mediating a massive K(+) efflux in Arabidopsis guard cells by the phosphatase AtPP2CA was investigated. Unlike the gork mutant, the atpp2ca mutants displayed a phenotype of reduced transpiration. We found that AtPP2CA interact...
