Applications

Our Abpromise guarantee covers the use of ab84934 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 210 kDa (predicted molecular weight: 195 kDa).

Target

  • FunctionThe N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions.
  • Tissue specificityThe alpha-containing isoform is found in most epithelial cell junctions. The short isoform is found both in endothelial cells and the highly specialized epithelial junctions of renal glomeruli and Sertoli cells of the seminiferous tubules.
  • Sequence similaritiesBelongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 3 PDZ (DHR) domains.
    Contains 1 SH3 domain.
    Contains 1 ZU5 domain.
  • DomainThe second PDZ domain mediates interaction with GJA12.
  • Post-translational
    modifications
    Phosphorylated. Dephosphorylated by PTPRJ.
  • Cellular localizationCell membrane. Cell junction > tight junction. Movement of ZO-1 from the cytoplasm to membrane is an early event occurring concurrently with cell-cell contact.

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 195 kDa
    Observed band size : 210 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 31 kDa,58 kDa. We are unsure as to the identity of these extra bands.
