Selective phosphatase inhibitors for protein phosphatase 1 ( PP1 ) and 2A ( PP2A ) that do not inhibit calcineurin , such as okadaic acid and calyculin A , also inhibited NFAT activation with IC50s of 87 nM and 4 nM, respectively, suggesting that okadaic acid and related inhibitors may block NFAT activation through the inhibition of PP1 , instead of PP2A .
