Biolegend, 828801, Purified anti-PP2AC Methyl (Leu 309) Antibody (Previously Covance catalog# MMS-5117)

PP2AC (Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform), encoded by the PPP2CA gene, is the main phosphatase for microtubule-associated proteins (MAPs). PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase. PP2AC is reversibly methyl esterified on Leu-309 by leucine carboxyl methyltransferase 1 (LCMT1) and protein phosphatase methylesterase 1 (PPME1). This carboxyl methylation influences the affinity of the catalytic subunit for the different regulatory subunits, which in turn, modulates the PP2A holoenzyme's enzyme activity and cellular localization.
