Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 36 kDa (predicted molecular weight: 37 kDa).
IP 1/50.
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IHC.
  • Target

    • Function
      Catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in MAP kinase p38 exclusively.
    • Tissue specificity
      Isoform 2 is only expressed in skeletal muscle. Isoform 1 is expressed in skeletal muscle, heart, and in lesser extent in liver or pancreas.
    • Sequence similarities
      Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.
      Contains 1 protein kinase domain.
    • Post-translational
      Weakly autophosphorylated.
      Acetylation of Ser-207 and Thr-211 by Yersinia yopJ prevents phosphorylation and activation, thus blocking the MAPK signaling pathway.

      ab33866 was shown to specifically react with MEK6 when MEK6 knockout samples were used. Wild-type and MEK6 knockout samples were subjected to SDS-PAGE. ab33866 and ab18058 (loading control to Vinculin) were diluted 1/10 000 and 1/2000 respectively and incubated overnight at 4ºC. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
