| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Dephosphorylates cellular tyrosine kinases, including PTK2B/PYK2, and thereby regulates signaling via PTK2B/PYK2. Ref.13 |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Subunit structure | Interacts with TGFB1I1 By similarity. Interacts with PSTPIP1. Interacts with PTK2B/PYK2. Interacts with LPXN By similarity. Ref.10 Ref.13 |
| Subcellular location | Cytoplasm. Cell projection › podosome By similarity. |
| Post-translational modification | Phosphorylated by STK24/MST3 and this results in inhibition of its activity. Ref.11 |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Non-receptor class 4 subfamily. Contains 1 tyrosine-protein phosphatase domain. |
| Sequence caution | The sequence BAD92761.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
