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 |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. A phosphoprotein + H2O = a protein + phosphate. |
| Subunit structure | Interacts with filamentous actin. Ref.1 |
| Subcellular location | Cytoplasm › cytoskeleton. Cell junction › focal adhesion. Note: Colocalizes with filamentous actin in the cytoplasm and the cell periphery. Also localizes to focal adhesions. Ref.1 |
| Tissue specificity | Expressed in brain, heart, liver, skeletal muscle, testis and thymus. Also expressed at lower levels in kidney, small intestine and spleen. Ref.1 |
| Developmental stage | Expressed in the nervous system at E14.5. Ref.1 |
| 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 BAE41593.1 differs from that shown. Reason: Intron retention. The sequence CAI24907.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI35940.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI51882.1 differs from that shown. Reason: Erroneous gene model prediction. |

Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q5SW75-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q5SW75-2) The sequence of this isoform differs from the canonical sequence as follows: 1-36: MALVTVQRSP...EEECRSQPRS → MTLSTLAGER...VISQNAINQL | ||||||
| Isoform 3 (identifier: Q5SW75-3) The sequence of this isoform differs from the canonical sequence as follows: 1-36: MALVTVQRSP...EEECRSQPRS → MTLSTLAGER...VISQNAINQL 133-133: S → R 134-1423: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 4 (identifier: Q5SW75-4) The sequence of this isoform differs from the canonical sequence as follows: 21-21: S → SSSYLEDSESAALLCCEYGESEIFSDFN | ||||||
| Note: Gene prediction based on EST data. No experimental confirmation available. |
