Modified residuei315 – 3151Leucine methyl ester By similarity

Post-translational modificationi

Reversibly methyl esterified on Leu-315 by leucine carboxyl methyltransferase 1 (PPM1) and protein phosphatase methylesterase 1 (PPE1). Carboxyl methylation influences the affinity of the catalytic subunit for the different regulatory subunits, thereby modulating the PP2A holoenzyme's substrate specificity, enzyme activity and cellular localization.
