CC -!- FUNCTION: Tyrosine-protein phosphatase which acts as a regulator of
CC endoplasmic reticulum unfolded protein response. Mediates
CC dephosphorylation of EIF2AK3/PERK; inactivating the protein kinase
CC activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-
CC src-induced signal transduction cascades. May regulate the EFNA5-EPHA3
CC signaling pathway which modulates cell reorganization and cell-cell
CC repulsion. May also regulate the hepatocyte growth factor receptor
CC signaling pathway through dephosphorylation of MET (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-
CC COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858,
CC ChEBI:CHEBI:82620; EC=3.1.3.48; Evidence={ECO:0000255|PROSITE-
CC ProRule:PRU10044};
CC -!- SUBUNIT: Interacts with EPHA3 (phosphorylated); dephosphorylates EPHA3
CC and may regulate its trafficking and function. Interacts with MET.
CC {ECO:0000250}.
CC -!- INTERACTION:
CC P20417; P00533: EGFR; Xeno; NbExp=11; IntAct=EBI-916819, EBI-297353;
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC {ECO:0000250}. Note=Interacts with EPHA3 at the cell membrane.
CC {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Found in several tissues including central nervous
CC system, liver and kidney. A high level of expression was found in the
CC hippocampus.
CC -!- PTM: Ser-50 is the major site of phosphorylation as compared to Ser-242
CC and Ser-243. Activated by phosphorylation at Ser-50 (By similarity).
CC {ECO:0000250}.
CC -!- PTM: S-nitrosylation of Cys-215 inactivates the enzyme activity.
CC {ECO:0000250}.
CC -!- PTM: Sulfhydration at Cys-215 following endoplasmic reticulum stress
CC inactivates the enzyme activity, promoting EIF2AK3/PERK activity.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-
CC receptor class 1 subfamily. {ECO:0000305}.
