Protein Phosphatase 2A (PP2A) dephosphorylates serine and threonine residues in proteins. This ubiquitously expressed enzyme plays a critical role in modulating cell survival, growth factor responses, and neurotransmission. Phosphorylation near the C-terminus at Y307 of the catalytic subunit decreases the phosphatase activity of PP2A and reduces its ability to bind to proteins such as CD28 and the glutamate receptor GluR5. Phosphorylation of PP2A at Y307 is highest during M-phase and lowest during S-phase of the cell cycle. Transient PP2A phosphorylation at this site is also observed in growth factor-stimulated cells.

Detection of Human Phospho-PP2A (Y307), Catalytic Subunit by Western Blot.
Western blot shows lysates of A549 human lung carcinoma cell line untreated (-) or treated (+) with hydroxyurea. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human/Mouse/Rat Phospho-PP2A (Y307), Catalytic Subunit Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3989), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-PP2A (Y307), Catalytic Subunit at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Phospho-PP2A (Y307), Catalytic Subunit by Western Blot
SAB298 inactivates PP2A, SHP2 via ERBB2 inhibition(A) SAB298 increases the levels of inactivated PP2A (pPP2A Y307) in YUSIK and YUSIV melanoma cells in a fashion similar to okadaic acid (Okadaic a). Active (unphosphorylated) PP2A is not dependent on the presence of pY416 SFK. Panels B and C show SHP2 inactivation by SAB298 in YUSIK, YUROB and YUSOC, but not YUGASP melanoma cells (pSHP2 Y542). Suppression of SHP2 is associated with SAB298 induced inactivation of ERBB2 (pERBB2 Y1196) (C, D).
