General annotation (Comments)
| Function | Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death. Extracellular stimuli such as proinflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK9/JNK2. In turn, MAPK9/JNK2 phosphorylates a number of transcription factors, primarily components of AP-1 such as JUN and ATF2 and thus regulates AP-1 transcriptional activity. In response to oxidative or ribotoxic stresses, inhibits rRNA synthesis by phosphorylating and inactivating the RNA polymerase I-specific transcription initiation factor RRN3. Promotes stressed cell apoptosis by phosphorylating key regulatory factors including TP53 and Yes-associates protein YAP1. In T-cells, MAPK8 and MAPK9 are required for polarized differentiation of T-helper cells into Th1 cells. Upon T-cell receptor (TCR) stimulation, is activated by CARMA1, BCL10, MAP2K7 and MAP3K7/TAK1 to regulate JUN protein levels. Plays an important role in the osmotic stress-induced epithelial tight-junctions disruption. When activated, promotes beta-catenin/CTNNB1 degradation and inhibits the canonical Wnt signaling pathway. Participates also in neurite growth in spiral ganglion neurons. Ref.1 Ref.7 Ref.10 Ref.13 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium By similarity. |
| Enzyme regulation | Activated by threonine and tyrosine phosphorylation by either of two dual specificity kinases, MAP2K4 and MAP2K7. MAP2K4 shows a strong preference for Tyr-185 while MAP2K7 phosphorylates Tyr-183 preferentially. Inhibited by dual specificity phosphatases, such as DUSP1. Ref.7 |
| Subunit structure | Interacts with MECOM. Binds to at least four scaffolding proteins, MAPK8IP1/JIP-1, MAPK8IP2/JIP-2, MAPK8IP3/JIP-3/JSAP1 and SPAG9/MAPK8IP4/JIP-4. These proteins also bind other components of the JNK signaling pathway. Interacts with NFATC4. Interacts with ATF7; the interaction does not phosphorylate ATF7 but acts as a docking site for ATF7-associated partners such as JUN. Interacts with BCL10. Interacts with CTNNB1 and GSK3B By similarity. Interacts with DCLK2. Ref.8 Ref.9 |
| Subcellular location | |
| Tissue specificity | All four isoforms are widely distributed in brain. Isoforms alpha-1 and alpha-2 are predominantly expressed in hippocampus, cerebral cortex, caudate-putamen, amygdala and the granule layer of the cerebellum. Alpha-1 is more abundant than alpha-2 in the periaqueductal region and the substantia nigra. Ref.3 |
| Induction | In T-cells, following T-cell receptor (TCR) activation. Levels peak 48 hours after TCR and CD-28 costimulation. Ref.1 Ref.7 |
| Domain | The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases. |
| Post-translational modification | Dually phosphorylated on Thr-183 and Tyr-185 by MAP2K7 and MAP2K4, which activates the enzyme. Autophosphorylated in vitro By similarity. Ref.11 Ref.12 |
| Sequence similarities | Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. Contains 1 protein kinase domain. |
