  • Target

    • Function

      Contributes to the organization of the actin cytoskeleton and cell structure. Plays a role in the regulation of cell migration. Plays a role in the invasiveness of cancer cells, and the formation of metastases.
    • Sequence similarities

      Contains 7 cortactin repeats.
      Contains 1 SH3 domain.
    • Domain

      The SH3 motif may mediate binding to the cytoskeleton.
    • Post-translational

      Tyrosine phosphorylation in transformed cells may contribute to cellular growth regulation and transformation.
    • Cellular localization

      Cytoplasm > cytoskeleton. Cell projection > lamellipodium. Cell projection > ruffle. Associated with membrane ruffles and lamellipodia.

    • Lane 1: Wild-type HAP1 cell lysate (40 µg)
      Lane 2: Cortactin knockout HAP1 cell lysate (40 µg)
      Lane 3: NIH3T3 cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab68438 observed at 70 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab68438 was shown to specifically recognize Cortactin in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when Cortactin knockout samples were examined. Wild-type and Cortactin knockout samples were subjected to SDS-PAGE. Ab68438 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10,000 dilution respectively and incubated overnight at 4C. 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 hour at room temperature before imaging.

      Lysates/proteins at 10 µg per lane.

      All lanes : HRP labelled goat anti-rabbit at 1/2000 dilution

      Predicted band size: 80 kDa
      Observed band size: 80 kDa
      Additional bands at: 75 kDa. We are unsure as to the identity of these extra bands.
