  • FunctionRequired 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.
  • Tissue specificityExpressed in several normal tissues and human tumor-derived cell lines.
  • Sequence similaritiesBelongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
    Contains 1 protein kinase domain.
  • Developmental stageIsoform 1 is activated specifically during the S and G2/M phases of the cell cycle.
  • Post-translational
    modifications
    Autophosphorylated. Isoform 1 undergoes phosphorylation mainly on Ser residues, and isoform 2 on both Ser and Thr residues.
  • Cellular localizationCytoplasm.
  • Information by UniProt
