Application Abreviews Notes
ELISA 1/1000.
WB 1/100 - 1/500. Detects a band of approximately 137 kDa (predicted molecular weight: 137 kDa).
IHC-P 1/50 - 1/100.


  • Function
    May play a role as scaffolding protein at cell-cell junctions. May regulate acid-induced ASIC3 currents by modulating its expression at the cell surface.
  • Tissue specificity
    Widely expressed with the exception of skeletal muscle. Isoform 1, isoform 2 and isoform 6 are highly expressed in colon, kidney, lung, liver, and pancreas. Isoform 5 is predominantly expressed in brain and heart. Isoform 3 and isoform 4 are highly expressed in pancreas and brain.
  • Sequence similarities
    Contains 1 guanylate kinase-like domain.
    Contains 6 PDZ (DHR) domains.
    Contains 2 WW domains.
  • Cellular localization
    Cell junction, tight junction. Cell membrane. Localizes to epithelial cells tight junctions.

Customer reviews and Q&As

Thank you for your patience. Here is the clarifying explanation regarding the immunogen: The immunogenic sequence was chosen based on the mutated sequence in Q96QZ7-3 or 4 and therefore it is absent in other isoforms including isoform 1.  It is i...
