In Alzheimer's disease, inhibition of PP2A activity by SET leads to hyper phosphorylation of the Tau protein [47]. PubMed:23454242
Up-regulation of I1 PP2A and I2 PP2A, and mislocalization and cleavage of I2 PP2A, could underlie the inactivation of PP2A in AD neocortical neurons (Tanimukai et al.,2005). PubMed:24653673
For instance, activated GSK3β has been reported to induce PP2A inactivation via several mechanisms: phosphorylation of PP2A on Tyr307 (Yao et al.,2011); demethylation of PP2A on Leu309 through inhibition of LCMT1 and up-regulation of PME1 (Yao et al.,2012); and accumulation of I2 PP2A (Liu et al.,2008a).

Complementing these findings, immu- nohistochemical and western blot studies have shown re- duced expression of PPMT [77], and up-regulation of the PP2A inhibitors I 1 and I 2 in AD cases [79, 80]. PubMed:22299660
The phosphoprotein SET is a potent inhibitor of PP2A activity [45]. PubMed:23454242
Natural toxins such as okadaic acid, calyculin ,and fostriecin (Reviewed in Swingle et al., 2007), and endogenous nuclear inhibitors called I1 PP2A and I2 PP2A/SET (Li and Damuni, 1998), can directly bind to the catalytic subunit and inhibit the phosphatase activity of the entire family of PP2A enzymes.
