ID:DYR1B_HUMAN DESCRIPTION: RecName: Full=Dual specificity tyrosine-phosphorylation-regulated kinase 1B; EC=2.7.12.1; AltName: Full=Minibrain-related kinase; AltName: Full=Mirk protein kinase; FUNCTION: Dual-specificity kinase which possesses both serine/ threonine and tyrosine kinase activities. Enhances the transcriptional activity of TCF1/HNF1A and FOXO1. Inhibits epithelial cell migration. Mediates colon carcinoma cell survival in mitogen-poor environments. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. ENZYME REGULATION: Inhibited by RANBP9. SUBUNIT: Dimer. Interacts with DCOHM, MAP2K3/MKK3, RANBP9 and TCF1/HNF1A. Part of a complex consisting of RANBP9, RAN, DYRK1B and COPS5. Interacts with DCAF7. INTERACTION: P20823:HNF1A; NbExp=4; IntAct=EBI-634187, EBI-636034; P46734:MAP2K3; NbExp=2; IntAct=EBI-634187, EBI-602462; Q9H0N5:PCBD2; NbExp=2; IntAct=EBI-634187, EBI-634289; Q96S59:RANBP9; NbExp=4; IntAct=EBI-634187, EBI-636085; SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Highest expression in skeletal muscle, testis, heart and brain with little expression in colon or lung. Expressed in a variety of tumor cell lines. PTM: Autophosphorylated on tyrosine residues. Phosphorylated by MAP kinase. Tyrosine phosphorylation may be required for dimerization. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MNB/DYRK subfamily. SIMILARITY: Contains 1 protein kinase 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.
