General annotation (Comments)
| Function | Negative regulator of TLR4 signaling. Does not activate JNK1/MAPK8 pathway, p38/MAPK14, nor ERK2/MAPK1 pathways. Ref.10 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium By similarity. UniProtKB P80192 |
| Enzyme regulation | Homodimerization via the leucine zipper domains is required for autophosphorylation and subsequent activation By similarity. UniProtKB Q16584 |
| Subunit structure | Homodimer By similarity. Interacts with TLR4. Ref.10 UniProtKB Q16584 |
| Post-translational modification | Autophosphorylation on serine and threonine residues within the activation loop plays a role in enzyme activation By similarity. UniProtKB Q16584 |
| Sequence similarities | Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. Contains 1 protein kinase domain. Contains 1 SH3 domain. |
| Sequence caution | The sequence BAB47433.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
