ID:CLK4_HUMAN DESCRIPTION: RecName: Full=Dual specificity protein kinase CLK4; EC=2.7.12.1; AltName: Full=CDC-like kinase 4; FUNCTION: Dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex and may be a constituent of a network of regulatory mechanisms that enable SR proteins to control RNA splicing. Phosphorylates SRSF1 and SRSF3. Required for the regulation of alternative splicing of MAPT/TAU. Regulates the alternative splicing of tissue factor (F3) pre-mRNA in endothelial cells. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. ENZYME REGULATION: TG003 inhibits its kinase activity and affects the regulation of alternative splicing mediated by phosphorylation of SR proteins (By similarity). SUBUNIT: Interacts with UBL5. SUBCELLULAR LOCATION: Nucleus (By similarity). TISSUE SPECIFICITY: Expressed in liver, kidney, heart, muscle, brain and endothelial cells. PTM: Autophosphorylates on all three types of residues. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. Lammer 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.
