일반 설명

Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform (UniProt: P67775; also known as EC:3.1.3.16, PP2A-alpha, Replication protein C, RP-C) is encoded by the PPP2CA gene (Gene ID: 5515) in human. Protein phosphatase 2A (PP2A) is a ubiquitously expressed enzyme that contributes 0.3 to 1% of the total cellular protein in the mammalian cell and regulates various functions by dephosphorylating many critical molecules, such as Akt, p53, c-Myc, CK2, S6 kinase, and β-catenin. It is the major phosphatase for microtubule-associated proteins (MAPs). PP2A acts as a pivotal cellular switch controlling important events in cell, such as cell cycle, apoptosis, and autophagy. It suppresses mitogenic signals and is suggested as a tumor suppressor. PP2A is made up of a functional heterotrimeric complex, which includes a structural subunit (PP2AA), a regulatory subunit (PP2AB), and a catalytic subunit (PP2AC). The regulatory subunit determines its substrate specificity. Over 20 different interchangeable regulatory subunits have been described that allows it to act on a large number of substrates. PP2AC has multiple metal ion binding sites and binds two manganese ions per subunit. Two isoforms of PP2AC ( and β) have been described that display high degree of homology. PP2AC alpha also has two isoforms (PP2AC alpha 1 and alpha 2). The PP2AC 2 isoform is shown to be catalytically inactive because it lacks amino acids 193-246. A critical posttranslational modification of PP2AC is the methylation/demethylation of leucine 309 by leucine carboxyl methyltransferase 1, which is shown to promote PP2A holoenzyme assembly and activation. Glucose deprivation is shown to cause membrane depolarization and influx of calcium through the L-type calcium channel and activation of CAM kinase 1, which along with protein phosphatase methylesterase 1 (PPME1) can demethyate and inactivate the catalytic subunit of PP2A (PP2AC).
