(Insulin Resistance) :
In addition, FoxO activity suppresses protein phosphatase 2A (PP2A) and disrupts Akt-PP2A and Akt-calcineurin interactions
Bertoli et al., Oncogene 2009
(Starvation) :
PP2A associates more tightly with Akt in CAPNS1 knockout cells, indicating that PP2A is involved in calpain mediated FoxO regulation
