WB 1/300 - 1/1000. Predicted molecular weight: 53 kDa.


  • 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.
  • Tissue specificity
    Expressed in several normal tissues and human tumor-derived cell lines.
  • Sequence similarities
    Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
    Contains 1 protein kinase domain.
  • Developmental stage
    Isoform 1 is activated specifically during the S and G2/M phases of the cell cycle.
  • Post-translational
    Autophosphorylated. Isoform 1 undergoes phosphorylation mainly on Ser residues, and isoform 2 on both Ser and Thr residues.

  • All lanes : Anti-MAP3K8 antibody (ab51208)

    Lane 1 : 293 cells treated with LPS (100ng/ml, 30min) with no immunizing peptide
    Lane 2 : 293 cells treated with LPS (100ng/ml, 30min) with immunizing peptide

    Predicted band size : 53 kDa
    Observed band size : ~60 kDa (why is the actual band size different from the predicted?)
