title: The AKT3 potassium channel protein interacts with the AtPP2CA protein phosphatase 2C.
abstract: The AKT3 potassium channel protein was identified as a strongly interacting partner of the Arabidopsis thaliana protein phosphatase 2C (AtPP2CA) in a yeast two-hybrid screen. A deletion analysis indicated that the catalytic domain of AtPP2CA was essential for the interaction with AKT3. Furthermore, the related PP2C phosphatase ABI1 did not interact with AKT3 in yeast.
