Abstract excerpt

The type 2A protein phosphatases (PP2As) are holoenzymes in all eukaryotes but their activators remain unknown in filamentous fungi. Fusarium graminearum contains three PP2As (FgPp2A, FgSit4, and FgPpg1), which play critical roles in fungal growth, development, and virulence. Here, we identified two PP2A activators (PTPAs), FgRrd1 and FgRrd2, and found that they control PP2A activity in a PP2A-specific manner....
