Figure Lengend Snippet: PTEN is a protein phosphatase for PKCδ in vitro (A) Purified PTEN proteins were used in a phosphatase assay in vitro using PKCδ as a substrate. The reaction was run for the described time interval. Changes in PKCδ phosphorylation at Y311, T505, and S643 were detected by immunoblotting. (B) Western blot showed PKCδ phosphorylation levels in a phosphatase assay in vitro using PKCδ as a substrate following the increased PTEN. The value of western blot band density was quantified by ImageJ analysis. After normalization with the value of PKCδ, the fold changes were presented to compare with 0 time point (0). (C) Western blot showed PKCδ phosphorylation levels in a phosphatase assay in vitro using PKCδ as a substrate following the increased PTEN with/without a phosphatase inhibitor. The value of western blot band density was quantified by ImageJ analysis. After normalization with the value of PKCδ, the fold change was presented to compare with 0 ng PTEN (0).
