Also known as magnesium-dependent protein phosphatase (PPM1A), this monomeric phosphatase is a member of a conserved group of proteins that acts on many different substrates in numerous pathways. PP2C-α inhibits p38 MAPK and SAPK\/JNK pathways activated in response to cell stress as seen in both and studies. Specifically, PP2C-α removes phosphates from MKK3 and MKK7, reducing activity of both proteins and inhibiting activation of the downstream kinases JNK and p38 MAPK, respectively (3). Another PP2C-α substrate is IKKβ, the critical regulator of NF-κB signaling. Dephosphorylation of IKKβ at Ser177\/181 by PPM1A and PPM1B results in inactivation of IKKβ and inhibition of NF-κB signaling (4). PP2C-α is one of the phosphatases responsible for removing phosphate residues from cyclin dependent protein kinases. In a study using HeLa cell extracts, PP2C-α dephospohrylates CDK2 and CDK6, with a preference toward interacting with CDK2 phosphorylated at Thr160, a residue found in the activating T-loop of the kinase. Removal of phosphates from this site is thought to inactivate cyclin-associated kinases (5). PP2C-α induces cell cycle arrest and apoptosis, likely through activation of p53 though other pathways may also contribute to PP2C-α mediated cell death (6). Additional PP2C-α substrates include the Wnt signaling pathway protein axin (7) and CFTR, a chloride channel protein implicated in cystic fibrosis (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nFLJ42306; MGC9201; phosphatase 2C alpha; PP2C-alpha; PP2CA; PP2Calpha; PPM1A; PPPM1A; Protein phosphatase 1A; protein phosphatase 1A (formerly 2C), magnesium-dependent, alpha isoform; protein phosphatase 2C alpha isoform; Protein phosphatase 2C isoform alpha; Protein phosphatase IA; protein phosphatase, Mg2+\/Mn2+ dependent 1A; protein phosphatase, Mg2+\/Mn2+ dependent, 1A\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk\nSENSITIVITY: Endogenous\nMW (kDa): 43\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799428747433,"sku":"3549S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3549s","provider":"Iright","version":"1.0","type":"link"}
