Product details:
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.
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.

Junctional Adhesion Molecule 1 also known as JAM-A or JAM-A protein is a member of the immunoglobulin superfamily. It has a mass of roughly 32 kDa. This molecule functions in tight junctions of epithelial and endothelial cells playing an important role in regulating paracellular permeability. JAM-A is expressed in tissues where tight junctions are present including the skin gastrointestinal tract and endothelia throughout the body.
Biological function summary
JAM-A functions as a cell adhesion molecule influencing processes like leukocyte transmigration and epithelial barrier formation. It does not act alone but rather forms complexes with other proteins at cell junctions. JAM-A interacts with other junctional proteins like occludin and claudins contributing to the structure and function of tight junctions.
Pathways
JAM-A participates in cellular processes involving inflammation and cell migration. It is an integral part of the signal transduction pathways that regulate leukocyte migration an important aspect of immune response. JAM-A is also associated with G-protein coupled receptors in these pathways highlighting its role in regulating intracellular signaling that affects cell adhesion and migration.
JAM-A has connections with cancer progression and cardiovascular diseases. Its overexpression has been linked to several cancers including breast cancer due to its role in enhancing cell migration and invasion. In cardiovascular diseases JAM-A interacts with platelet-endothelial cell adhesion molecule-1 (PECAM-1) influencing the inflammatory response within vascular tissues. Understanding these interactions can aid in developing therapeutic strategies targeting JAM-A in related diseases.
