  • Target

    • Function
      Acts as a scaffold for the formation of a ternary MAP3K2/MAP3K3-MAP3K5-MAPK7 signaling complex. Activation of this pathway appear to play a critical role in protecting cells from stress-induced apopotosis, neuronal survival and cardiac development and angiogenesis.
    • Tissue specificity
      Expressed in many adult tissues. Abundant in heart and skeletal muscle.
    • Sequence similarities
      Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.
      Contains 1 OPR domain.
      Contains 1 protein kinase domain.
    • Domain
      Binds MAP3K2/MAP3K3 and MAPK7 via non-overlapping residues of the OPR domain. This domain also mediates interactions with SQSTM1 and PARD6A.
    • Post-translational
      Activated by phosphorylation on Ser/Thr by MAP kinase kinase kinases.
      Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway.

    • Anti-MEK5 antibody [EP648Y] (ab45146) at 1/10000 dilution (unpurified) + HeLa cell lysate

      Predicted band size : 49 kDa
      Observed band size : 49 kDa
    • Immunofluorescent staining of HeLa using unpurified ab45146.

    • Unpurified ab45146 at 1/100 staining HeLa cells by ICC/IF. The cells were paraformaldehyde fixed and blocked with goat serum prior to incubation with the antibody for 45 minutes. An Alexa Fluor® 488 conjugated goat polyclonal antibody was used as the secondary. This antibody detects MEK5 in HeLa cells as a cytoplasmic protein.
