Protein attributes
| Sequence length | 347 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Dual specificity kinase. Is activated by cytokines and environmental stress in vivo. Catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the MAP kinase p38. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Enzyme regulation | Activated by dual phosphorylation on Ser-218 and Thr-222. |
| Subunit structure | Binds to DYRK1B/MIRK and increases its kinase activity. Part of a complex with MAP3K3, RAC1 and CCM2. Interacts with ARRB1. Interacts with Yersinia yopJ. Ref.8 Ref.9 Ref.10 |
| Tissue specificity | Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues. |
| Post-translational modification | Autophosphorylated. Phosphorylation on Ser-218 and Thr-222 by MAP kinase kinase kinases regulates positively the kinase activity. Phosphorylated by TAOK2. Ref.6 Ref.7 Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway. |
| Involvement in disease | Defects in MAP2K3 may be involved in colon cancer. |
| Sequence similarities | Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily. Contains 1 protein kinase domain. |
