Application Abreviews Notes
Flow Cyt 1/15.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

WB 1/5000. Detects a band of approximately 100 kDa (predicted molecular weight: 93 kDa).
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for IHC-Fr,IHC-P or IP.
  • Target

    • Function
      Activates the JUN N-terminal pathway. Required for serum-stimulated cell proliferation and for mitogen and cytokine activation of MAPK14 (p38), MAPK3 (ERK) and MAPK8 (JNK1). Plays a role in mitogen-stimulated phosphorylation and activation of BRAF, but does not phosphorylate BRAF directly. Influences microtubule organization during the cell cycle.
    • Tissue specificity
      Expressed in a wide variety of normal and neoplastic tissues including fetal lung, liver, heart and kidney, and adult lung, liver, heart, kidney, placenta, skeletal muscle, pancreas and brain.
    • Sequence similarities
      Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
      Contains 1 protein kinase domain.
      Contains 1 SH3 domain.
    • Post-translational
      Autophosphorylation on serine and threonine residues within the activation loop plays a role in enzyme activation. Thr-277 is likely to be the main autophosphorylation site. Phosphorylation of Ser-555 and Ser-556 is induced by CDC42.
    • Cellular localization
      Cytoplasm > cytoskeleton > centrosome. Location is cell cycle dependent.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: MLK3 knockout HAP1 cell lysate (20 µg)
      Lane 3: A431 cell lysate (20 µg)
      Lane 4: HeLa cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab51068 observed at 105 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab51068 was shown to specifically react with MLK3 when MLK3 knockout samples were used. Wild-type and MLK3 knockout samples were subjected to SDS-PAGE. ab51068 and ab8245 (loading control to GAPDH) were diluted 1/5000 and 1/1000 respectively and incubated overnight at 4°C. 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 1/10000 dilution for 1 hour at room temperature before imaging.

      Predicted band size: 93 kDa
      Observed band size: 100 kDa (why is the actual band size different from the predicted?)
