  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Function
      Phosphorylates microtubule-associated protein 2 (MAP2). May promote entry in the cell cycle.
    • Tissue specificity
      Highest expression in the skeletal muscle, followed by the brain. Also found in heart, placenta, lung, liver, pancreas, kidney and skin fibroblasts.
    • Sequence similarities
      Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
      Contains 1 protein kinase domain.
    • Domain
      The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
    • Post-translational
      Dually phosphorylated on Thr-626 and Tyr-628, which activates the enzyme.

    • Anti-MAPK6 / ERK-3 antibody [EP1720Y] (ab53277) at 1/1000 dilution + HeLa cell lysate at 10 µg

      Goat anti-Rabbit HRP labeled at 1/2000 dilution

      Predicted band size: 63 kDa
      Observed band size: 105 kDa (why is the actual band size different from the predicted?)

    • Overlay histogram showing A431 cells stained with ab53277 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab53277, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
