General annotation (Comments)
| Function | Protein phosphatase which regulates actin filament dynamics. Dephosphorylates and activates the actin binding/depolymerizing factor cofilin, which subsequently binds to actin filaments and stimulates their disassembly. Inhibitory phosphorylation of cofilin is mediated by LIMK1, which may also be dephosphorylated and inactivated by this protein. Ref.1 Ref.5 Ref.6 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. A phosphoprotein + H2O = a protein + phosphate. |
| Subunit structure | Interacts with actin and this stimulates phosphatase activity. Also interacts with LIMK1 and with the 14-3-3 proteins YWHAB, YWHAG, YWHAQ, and YWHAZ. Interaction with 14-3-3 proteins inhibits phosphatase activity and also blocks recruitment to lamellipodia and stimulation by actin. Ref.1 Ref.5 Ref.10 Ref.11 |
| Subcellular location | Cytoplasm › cytoskeleton. Cell projection › lamellipodium. Cleavage furrow. Midbody. Note: Also recruited to actin rich membrane protrusions such as lamellipodia, which may allow local control of actin dynamics at sites of cell locomotion. Also localized to the cleavage furrow and the midbody during cytokinesis. Ref.6 Ref.8 Ref.9 Ref.10 Ref.13 |
| Post-translational modification | Phosphorylated. Inhibitory phosphorylation by PAK4 promotes binding to YWHAZ. Phosphorylation at Ser-978 is decreased by stimuli which promote actin reorganization and lamellipodia formation. Can be dephosphorylated and activated by PPP3CA/calcineurin A. Phosphorylation decreases immediately prior to telophase. Ref.6 Ref.10 Ref.11 Ref.12 |
| Miscellaneous | Tyrosine phosphatase activity has not been demonstrated for this protein to date. |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Contains 1 tyrosine-protein phosphatase domain. |
| Sequence caution | The sequence BAA92536.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
