Catalytic Activity [a protein]-serine/threonine phosphate + H(2)O = [a protein]-serine/threonine + phosphate.
Catalytic Activity Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate. {ECO:0000255|PROSITE-ProRule:PRU10044}.
Function Inactivates MAPK1 and MAPK3 which leads to dephosphorylation of heat shock factor protein 4 and a reduction in its DNA-binding activity. Inhibits MAP kinase p38 by dephosphorylating it and inhibits p38-mediated apoptosis in anaplastic thyroid cancer cells. Can also induce activation of MAP kinase p38 and c-Jun N-terminal kinase (JNK). {ECO:0000269|PubMed:15796912, ECO:0000269|PubMed:16581800, ECO:0000269|PubMed:16924234, ECO:0000269|PubMed:17001450}.
Interaction P04637:TP53; NbExp=9; IntAct=EBI-2924519, EBI-366083;
Similarity Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily. {ECO:0000305}.
Similarity Contains 1 tyrosine-protein phosphatase domain. {ECO:0000305}.
Subcellular Location Cytoplasm. Nucleus. Golgi apparatus.
Subunit Interacts with HSF4. {ECO:0000269|PubMed:16581800}.
Tissue Specificity Brain. In the brain it is expressed ubiquitously except in the hippocampus. Expressed in embryonal cancers (retinoblastoma, neuroepithilioma and neuroblastoma) and in anaplatic thyroid cancer. {ECO:0000269|PubMed:15796912, ECO:0000269|PubMed:16581800, ECO:0000269|PubMed:16924234, ECO:0000269|PubMed:17001450}.
