Protein Structure
UniProt Annotation
Function Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Promotes tumors. Inhibits geranylgeranyl transferase type II activity by blocking the association between RABGGTA and RABGGTB. {ECO:0000269PubMed:14643450}.
Subcellular Localization Cell membrane. Early endosome. Cytoplasm.
Disease Associations
Tissue Specificity Ubiquitously expressed, with highest levels in skeletal muscle, heart and thymus. Overexpressed in prostate tumor tissue. {ECO:0000269PubMed:10940933, ECO:0000269PubMed:11734337, ECO:0000269PubMed:8661118}.
