Our Abpromise guarantee covers the use of ab83891 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 77 kDa (predicted molecular weight: 77 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    May play a role in tight junctions biogenesis and in the establishment of cell polarity in epithelial cells. May modulate SC6A1/GAT1-mediated GABA uptake by stabilizing the transporter. Required for localization of EZR to the apical membrane of parietal cells and may play a role in the dynamic remodeling of the apical cytoskeleton.
  • Tissue specificity
    Expressed in the retina (at protein level).
  • Sequence similarities
    Belongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 2 L27 domains.
    Contains 1 PDZ (DHR) domain.
    Contains 1 SH3 domain.
  • Domain
    The L27 domain 1 functions in targeting to the tight junctions by binding to INADL.
    The PDZ domain binds to the C-terminus of SC6A1.
  • Cellular localization
    Cell membrane. Endomembrane system. Cell junction > tight junction. Localized to the tight junctions of epithelial cells and a subset of intracellular vesicles. In the retina, detected at the outer limiting membrane (OLM), apical to the adherens junction (AJ), where it colocalizes with CRB1. Colocalizes with MPP1 in the retina at the outer limiting membrane (OLM). Localized to the Purkinje cell body and axon.
