Application Abreviews Notes
  • Application notesELISA: 1/2000.
    WB: Use at a concentration of 1 - 3 µg/ml. Detects a band of approximately 21 kDa in HeLa and A549 lysates (predicted molecular weight: 20 kDa).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionProtein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. May play a role in the development and maintenance of differentiating epithelial tissues. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis.
    • Tissue specificityExpressed in bone marrow, lymph nodes, T lymphocytes, spleen, thymus and tonsil. Overexpressed in tumor cell lines.
    • Sequence similaritiesBelongs to the protein-tyrosine phosphatase family.
      Contains 1 tyrosine-protein phosphatase domain.
    • Developmental stageExpressed in fetal liver.
    • Post-translational
      Farnesylated. Farnesylation is required for membrane targeting. Unfarnesylated forms are shifted into the nucleus.
    • Cellular localizationCell membrane. Early endosome. Endoplasmic reticulum. Cytoplasm. Cytoplasm > cytoskeleton > spindle. And mitotic spindle.
