  • Product overview

    The Human Junctional Adhesion Molecule 1/JAM-A Enzyme-Linked Immunosorbent Assay (ELISA) kit (ab213800) is designed for the quantitative detection of Human JAM-A in cell culture supernatants and serum.

    The ELISA kit is based on standard sandwich enzyme-linked immunosorbent assay technology. A monoclonal antibody from mouse specific for JAM-A has been pre-coated onto 96-well plates. Standards (Expression system for standard: E.coli; Immunogen sequence: S28-V238) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for JAM-A is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human JAM-A amount of sample captured in plate. 

  • Notes

    Junctional adhesion molecule A/JAM-A is a protein that in humans is encoded by the F11R gene. It is mapped to 1q23.3. This gene is an immunoglobulin-like molecule that co-localizes with tight junctions in endothelium and epithelium and is also found on blood leukocytes and platelets. JAM-A plays an important role in the regulation of tight junction assembly in epithelia. In addition, it can act as a receptor for reovirus, a ligand for the integrin LFA1, involved in leukocyte transmigration and a platelet receptor. JAM-A has a non-redundant role in controlling DC motility, trafficking to lymph nodes, and activation of specific immunity.

  • Research areas

  • Function

    Seems to plays a role in epithelial tight junction formation. Appears early in primordial forms of cell junctions and recruits PARD3. The association of the PARD6-PARD3 complex may prevent the interaction of PARD3 with JAM1, thereby preventing tight junction assembly (By similarity). Plays a role in regulating monocyte transmigration involved in integrity of epithelial barrier. Involved in platelet activation. In case of orthoreovirus infection, serves as receptor for the virus.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily.
    Contains 2 Ig-like V-type (immunoglobulin-like) domains.
  • Post-translational

  • Cellular localization

    Cell junction > tight junction. Cell membrane. Localized at tight junctions of both epithelial and endothelial cells.
