Background: Protein Phosphatase 1A (PPM1A) is a member of the PP2C family of Ser/Thr protein phosphatases which are known to be negative regulators of cell stress response pathways. PPM1A has a broad specificity. PPM1A negatively regulates the activities of MAP kinases and MAP kinase kinases. Also; it negatively regulates TGF-beta signaling through dephosphorylating SMAD2 and SMAD3; resulting in their dissociation from SMAD4; nuclear export of the SMADs and termination of the TGF-beta-mediated signaling. In addition; PPM1A can dephosphorylate cyclin-dependent kinases; and thus may be involved in cell cycle control.
Sequence: Gly2-Trp382
Purity: > 95 % as determined by reducing SDS-PAGE.
