PP2A is a heterotrimeric phosphatase consisting of a catalytic C subunit (PP2Ac), a scaffolding A subunit, and a regulatory B subunit. Multiple isoforms create diverse holoenzymes with distinct functions.
PP2A is a major serine/threonine phosphatase regulating numerous cellular processes including cell cycle, metabolism, and signal transduction. It dephosphorylates tau, regulatory proteins, and transcription factors. PP2A is essential for normal brain function.
PP2A activity is reduced in AD brains, contributing to tau hyperphosphorylation. The phosphatase is inhibited by A-beta and by methylation changes. Restoring PP2A activity is a therapeutic target. PP2A deregulation is also seen in PD and HD.
PP2A activators are being developed for AD. Sodium selenate and other compounds activate PP2A. Challenges include isoform specificity and avoiding off-target effects.
