ID:M3K8_HUMAN DESCRIPTION: RecName: Full=Mitogen-activated protein kinase kinase kinase 8; EC=2.7.11.25; AltName: Full=Cancer Osaka thyroid oncogene; AltName: Full=Proto-oncogene c-Cot; AltName: Full=Serine/threonine-protein kinase cot; AltName: Full=Tumor progression locus 2; Short=TPL-2; FUNCTION: Required for TLR4 activation of the MEK/ERK pathway. Able to activate NF-kappa-B 1 by stimulating proteasome-mediated proteolysis of NF-kappa-B 1/p105. Plays a role in the cell cycle. The longer form has some transforming activity, although it is much weaker than the activated cot oncoprotein. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. COFACTOR: Magnesium. SUBUNIT: Forms a ternary complex with NFKB1 and TNIP2. INTERACTION: Q8NFZ5:TNIP2; NbExp=8; IntAct=EBI-354900, EBI-359372; SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Expressed in several normal tissues and human tumor-derived cell lines. DEVELOPMENTAL STAGE: Isoform 1 is activated specifically during the S and G2/M phases of the cell cycle. PTM: Autophosphorylated. Isoform 1 undergoes phosphorylation mainly on Ser residues, and isoform 2 on both Ser and Thr residues. SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily. SIMILARITY: Contains 1 protein kinase domain. WEB RESOURCE: Name=SeattleSNPs; URL="http://pga.gs.washington.edu/data/map3k8/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
