  • Function

    Enzyme with a broad specificity. 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.
  • Sequence similarities

    Belongs to the PP2C family.
  • Cellular localization

    Lane 2: PPM1A knockout HAP1 cell lysate (20 µg)
    Lane 3: HeLa cell lysate (20 µg)
    Lane 4: Jurkat cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab135249 observed at 42 kDa. Red - loading control, ab18251, observed at 37 kDa.

    ab135249 was shown to specifically react with PPM1A when PPM1A knockout samples were used. Wild-type and PPM1A knockout samples were subjected to SDS-PAGE. ab135249 at a dilution of 1/500 and ab18251 (loading control to alpha Tubulin) at a dilution of 1/10,000 were incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed ab216772 and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed ab216777 secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
