General annotation (Comments)
| Function | Tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation of EIF2AK3/PERK; inactivating the protein kinase activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades. May regulate the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion By similarity. |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Subunit structure | Interacts with EPHA3 (phosphorylated); dephosphorylates EPHA3 and may regulate its trafficking and function By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: Interacts with EPHA3 at the cell membrane By similarity. |
| Tissue specificity | Found in several tissues including central nervous system, liver and kidney. A high level of expression was found in the hippocampus. |
| Post-translational modification | Ser-50 is the major site of phosphorylation as compared to Ser-242 and Ser-243. Activated by phosphorylation at Ser-50 By similarity. S-nitrosylation of Cys-215 inactivates the enzyme activity By similarity. Sulfhydration at Cys-215 following endoplasmic reticulum stress inactivates the enzyme activity, promoting EIF2AK3/PERK activity By similarity. |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily. Contains 1 tyrosine-protein phosphatase domain. |
