| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Activates the JUN N-terminal pathway through activation of the MAP kinase kinase MAP2K7. Acts synergistically with PRDX3 to regulate the activation of NF-kappa-B in the cytosol. This activation is kinase-dependent and involves activating the IKK complex, the IKBKB-containing complex that phosphorylates inhibitors of NF-kappa-B. Ref.1 Ref.8 Ref.9 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. Ref.1 |
| Cofactor | Magnesium By similarity. UniProtKB Q60700 |
| Enzyme regulation | Activated by autophosphorylation and homodimerization. Ref.1 Ref.7 |
| Subunit structure | Homodimer; forms dimers through the leucine-zipper motif. Interacts with the C-terminus of MAPK8IP1 through the kinase catalytic domain. Binds PRDX3. Associates with the IKK complex through the kinase domain. Ref.7 Ref.8 Ref.9 |
| Subcellular location | |
| Tissue specificity | Expressed in the adult brain, liver, placenta and pancreas, with expression strongest in the pancreas. Ref.1 |
| Post-translational modification | Autophosphorylated on serine and threonine residues. 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 AAI11727.1 differs from that shown. Reason: Erroneous translation. Wrong choice of CDS. The sequence BAG59505.1 differs from that shown. Reason: Erroneous termination at position 740. Translated as Tyr. |

Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: O43283-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: O43283-3) The sequence of this isoform differs from the canonical sequence as follows: 159-160: DT → VF 161-966: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. No experimental confirmation available. | ||||||
| Isoform 3 (identifier: O43283-4) The sequence of this isoform differs from the canonical sequence as follows: 1-144: Missing. 145-159: IGKAYSTDYKLQQQD → MSYVECKCLQLENKN | ||||||
| Isoform 4 (identifier: O43283-5) The sequence of this isoform differs from the canonical sequence as follows: 1-207: Missing. 208-220: LRKLKHPNIIAFK → MYCGIQILALWER | ||||||
| Isoform 5 (identifier: O43283-6) The sequence of this isoform differs from the canonical sequence as follows: 122-128: RSGSGSG → RYLGSAI 129-966: Missing. |
