  • Function
    Protein 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 specificity
    Expressed in bone marrow, lymph nodes, T lymphocytes, spleen, thymus and tonsil. Overexpressed in tumor cell lines.
  • Sequence similarities
    Belongs to the protein-tyrosine phosphatase family.
    Contains 1 tyrosine-protein phosphatase domain.
  • Developmental stage
    Expressed in fetal liver.
  • Post-translational
    modifications
    Farnesylated. Farnesylation is required for membrane targeting. Unfarnesylated forms are shifted into the nucleus.
  • Cellular localization
    Cell membrane. Early endosome. Endoplasmic reticulum. Cytoplasm. Cytoplasm > cytoskeleton > spindle. And mitotic spindle.
  • Information by UniProt
