  • FunctionMay play an important role in CKII- and p60c-src-induced signal transduction cascades.
  • Sequence similaritiesBelongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.
    Contains 1 tyrosine-protein phosphatase domain.
  • Post-translational
    modifications
    Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.
  • Cellular localizationEndoplasmic reticulum membrane.
  • Information by UniProt
