Protein attributes
| Sequence length | 1608 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Component of a protein kinase signal transduction cascade. Activates the CSBP2, P38 and JNK MAPK pathways, but not the ERK pathway. Specifically phosphorylates and activates MAP2K4 and MAP2K6. Ref.1 Ref.7 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium. |
| Enzyme regulation | N-terminal autoinhibitory domain interacts with the C-terminal kinase domain, inhibiting kinase activity, and preventing interaction with its substrate, MAP2K6. The GADD45 proteins activate the kinase by binding to the N-terminal domain. Activated by phosphorylation on Thr-1505. Ref.7 |
| Subunit structure | Monomer and homodimer. Homodimerization enhances kinase activity. Interacts with TRAF4; this promotes homodimerization By similarity. Binds both upstream activators and downstream substrates in multimolecular complexes. Interacts with AXIN1 and DIXDC1; interaction with DIXDC1 prevents interaction with AXIN1. Ref.7 Ref.8 Ref.9 |
| Subcellular location | Cytoplasm › perinuclear region By similarity. Note: Localized in perinuclear vesicular-like structures, probably Golgi-associated vesicles By similarity. |
| Tissue specificity | Expressed at high levels in heart, placenta, skeletal muscle and pancreas, and at lower levels in other tissues. Ref.1 |
| Sequence similarities | Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. Contains 1 protein kinase domain. |
| Sequence caution | The sequence BAA13204.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence CAC12766.2 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH70639.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH70640.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI20815.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI20816.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI21477.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI41309.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI41310.1 differs from that shown. Reason: Erroneous gene model prediction. |
