In this review , we highlight how PP2A holoenzyme biogenesis and enzymatic activity are controlled by a sophisticatedly coordinated network of five PP2A modulators , consisting of alpha 4 , phosphatase 2A phosphatase activator ( PTPA ) , leucine carboxyl methyl transferase 1 ( LCMT1 ) , PP2A methyl esterase 1 ( PME - 1 ) and , potentially , target of rapamycin signaling pathway regulator - like 1 ( TIPRL1 ) , which serve to prevent promiscuous phosphatase activity until the holoenzyme is completely assembled .
