| Formulation | Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |
| Reconstitution | It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis |
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.
