  • Target

    • Function

      Calcium-dependent, calmodulin-stimulated protein phosphatase. This subunit may have a role in the calmodulin activation of calcineurin. Dephosphorylates DNM1L, HSPB1 and SSH1.
    • Sequence similarities

      Belongs to the PPP phosphatase family. PP-2B subfamily.
    • Cellular localization

      Nucleus. Colocalizes with ACTN1 and MYOZ2 at the Z line in heart and skeletal muscle.

      Lane 3: A431 cell lysate (20 µg)
      Lane 4: HeLa cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab109412 observed at 60 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab109412 was shown to specifically react with Calcineurin A when Calcineurin A knockout samples were used. Wild-type and Calcineurin A knockout samples were subjected to SDS-PAGE. ab109412 and ab8245 (loading control to GAPDH) were both diluted 1/10000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    • Overlay histogram showing HeLa cells stained with ab109412 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab109412, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
