PTEN is reversibly oxidized in various cells by exogenous hydrogen peroxide as well as by endogenous hydrogen peroxide generated when cells are stimulated with growth factors, cytokines and hormones. A gel mobility shift assay showed that oxidized PTEN migrated more rapidly than reduced PTEN on a non-reducing SDS–PAGE gel. Oxidized PTEN was reduced when treated with dithiothreitol. Supplementation...
Protein tyrosine phosphatase (PTP) is a family of enzymes important for regulating cellular phosphorylation state. The oxidation and consequent inactivation of several PTPs by H 2 O 2 are well demonstrated. It is also shown that recovery of enzymatic activity depends on the availability of cellular reductants. Among these redox-regulated PTPs, PTEN, Cdc25 and low molecular weight PTP...
