ID:STK39_HUMAN DESCRIPTION: RecName: Full=STE20/SPS1-related proline-alanine-rich protein kinase; Short=Ste-20-related kinase; EC=2.7.11.1; AltName: Full=DCHT; AltName: Full=Serine/threonine-protein kinase 39; FUNCTION: May act as a mediator of stress-activated signals. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. SUBUNIT: The phosphorylated form forms a complex with WNK2 (By similarity). SUBCELLULAR LOCATION: Cytoplasm (Probable). Nucleus (Probable). Note=Nucleus when caspase-cleaved (Probable). TISSUE SPECIFICITY: Predominantly expressed in brain and pancreas followed by heart, lung, kidney, skeletal muscle, liver, placenta and testis. DOMAIN: PAPA box (proline-alanine repeats) may target the kinase to a specific subcellular location by facilitating interaction with intracellular proteins such as actin or actin-like proteins. PTM: Phosphorylated at Ser-309 by PRKCQ. SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 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.
