Protein attributes
| Sequence length | 619 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Component of a protein kinase signal transduction cascade. Regulates the JNK and ERK5 pathways by phosphorylating and activating MAP2K5 and MAP2K7 By similarity. Plays a role in caveolae kiss-and-run dynamics. Ref.8 Ref.10 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium. |
| Enzyme regulation | Activated by phosphorylation on Thr-524 By similarity. |
| Subunit structure | Interacts with PKN2; the interaction activates PKN2 kinase activity in a MAP3K2-independent kinase activity By similarity. Self-associates. Binds both upstream activators and downstream substrates in multimolecular complexes. Interacts (via the kinase catalytic domain) with STK38. Interacts with XIAP/BIRC4. Ref.8 Ref.12 Ref.16 |
| Subcellular location | Cytoplasm. Nucleus. Note: Upon EGF stimulation, translocates into the nucleus. Ref.9 |
| Post-translational modification | Autophosphorylated By similarity. Ubiquitination by XIAP/BIRC4 does not lead to proteasomal degradation. |
| Sequence similarities | Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. Contains 1 OPR domain. Contains 1 protein kinase domain. |
| Sequence caution | The sequence BAC11348.1 differs from that shown. Reason: Erroneous initiation. |
