ID:DUS26_HUMAN DESCRIPTION: RecName: Full=Dual specificity protein phosphatase 26; EC=3.1.3.16; EC=3.1.3.48; AltName: Full=Dual specificity phosphatase SKRP3; AltName: Full=Low-molecular-mass dual-specificity phosphatase 4; Short=DSP-4; Short=LDP-4; AltName: Full=Mitogen-activated protein kinase phosphatase 8; Short=MAP kinase phosphatase 8; Short=MKP-8; AltName: Full=Novel amplified gene in thyroid anaplastic cancer; 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). CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate. CATALYTIC ACTIVITY: A phosphoprotein + H(2)O = a protein + phosphate. SUBUNIT: Interacts with HSF4. INTERACTION: P04637:TP53; NbExp=9; IntAct=EBI-2924519, EBI-366083; SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Golgi apparatus. 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. SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily. SIMILARITY: Contains 1 tyrosine-protein phosphatase domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
