ID:TP4A1_HUMAN DESCRIPTION: RecName: Full=Protein tyrosine phosphatase type IVA 1; EC=3.1.3.48; AltName: Full=PTP(CAAXI); AltName: Full=Protein-tyrosine phosphatase 4a1; AltName: Full=Protein-tyrosine phosphatase of regenerating liver 1; Short=PRL-1; Flags: Precursor; 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. CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate. ENZYME REGULATION: Inhibited by sodium orthovanadate and pentamidine. SUBUNIT: Homotrimer. Interacts with ATF5 (By similarity). Interacts with tubulin. SUBCELLULAR LOCATION: Cell membrane. Early endosome. Endoplasmic reticulum. Cytoplasm. Cytoplasm, cytoskeleton, spindle. Note=And mitotic spindle. TISSUE SPECIFICITY: Expressed in bone marrow, lymph nodes, T lymphocytes, spleen, thymus and tonsil. Overexpressed in tumor cell lines. DEVELOPMENTAL STAGE: Expressed in fetal liver. INDUCTION: Strongly down-regulated upon tetrodotoxin treatment. PTM: Farnesylated. Farnesylation is required for membrane targeting. Unfarnesylated forms are shifted into the nucleus. SIMILARITY: Belongs to the protein-tyrosine phosphatase family. SIMILARITY: Contains 1 tyrosine-protein phosphatase domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
