Our Abpromise guarantee covers the use of ab96587 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
IHC-P Use at an assay dependent concentration.
ICC/IF 1/100 - 1/1000.
WB 1/500 - 1/3000. Predicted molecular weight: 187 kDa.


  • Function
    The 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 specificity
    The 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 similarities
    Belongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 3 PDZ (DHR) domains.
    Contains 1 SH3 domain.
    Contains 1 ZU5 domain.
  • Domain
    The second PDZ domain mediates interaction with GJA12.
  • Post-translational
    Phosphorylated. Dephosphorylated by PTPRJ.
  • Cellular localization
    Cell membrane. Cell junction > tight junction. Movement of ZO-1 from the cytoplasm to membrane is an early event occurring concurrently with cell-cell contact.
