Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.

IP Use at 1-4 µg/mg of lysate.


  • Function

    Protein phosphatase that mediates dephosphorylation of 'Ser-473' of AKT1, 'Ser-660' of PRKCB isoform beta-II and 'Ser-657' of PRKCA. AKT1 regulates the balance between cell survival and apoptosis through a cascade that primarily alters the function of transcription factors that regulate pro- and antiapoptotic genes. Dephosphorylation of 'Ser-473' of AKT1 triggers apoptosis and decreases cell proliferation. Also controls the phosphorylation of AKT3. Dephosphorylation of PRKCA and PRKCB leads to their destabilization and degradation. Inhibits cancer cell proliferation and may act as a tumor suppressor.
  • Tissue specificity

    In colorectal cancer tissue, expression is highest in the surface epithelium of normal colonic mucosa adjacent to the cancer tissue but is largely excluded from the crypt bases. Expression is lost or significantly decreased in 80% of tested tumors (at protein level).
  • Sequence similarities

    Contains 22 LRR (leucine-rich) repeats.
    Contains 1 PH domain.
    Contains 1 PP2C-like domain.
  • Cellular localization

    Cytoplasm. Membrane. Nucleus. In colorectal cancer tissue, expression is concentrated in the cytoplasm and nucleus.

  • Detection of PHLPP2 by Western Blot of Immunoprecipitate.
    ab71973 at 1µg/ml staining PHLPP2 in HeLa whole cell lysate immunoprecipitated using ab71973 at 3µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
    Detection: chemiluminescence with exposure time of 30 seconds.
  • ab71973 stained A549 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab71973 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
