      Alternate Names
      • Junctional Adhesion Molecule-1
      Background InformationJunctional Adhesion Molecules (JAMs) are components and regulators of the well-characterized epithelial and endothelial tight junction. JAM is selectively concentrated at intercellular junctions of endothelial and epithelial cells of different origins. Microscopy shows that JAM codistributes with tight junction components at the apical region of the intercellular cleft. A mAb directed to JAM (BV11) was found to inhibit spontaneous and chemokine-induced monocyte transmigration through an endothelial cell monolayer in vitro. Systemic treatment of mice with BV11 mAb blocked monocyte infiltration upon chemokine administration in subcutaneous air pouches (1). The human protein shares a highly conserved structure and sequence with the murine protein. However it is distinct in that it is constitutively expressed on circulating neutrophils, monocytes, platelets and lymphocyte subsets (2).

      Entrez Gene Number
      Entrez Gene SummaryTight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. The protein encoded by this immunoglobulin superfamily gene member is an important regulator of tight junction assembly in epithelia. In addition, the encoded protein can act as (1) a receptor for reovirus, (2) a ligand for the integrin LFA1, involved in leukocyte transmigration, and (3) a platelet receptor. Multiple 5' alternatively spliced variants, encoding the same protein, have been identified but their biological validity has not been established.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q9Y624 # 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.
      SIZE: 299 amino acids; 32583 Da
      SUBUNIT: Interacts with the first PDZ domain of PARD3. The association between PARD3 and PARD6B probably disrupts this interaction (By similarity). Interacts with the ninth PDZ domain of MPDZ.
      SUBCELLULAR LOCATION: Cell junction, tight junction; Single-pass type I membrane protein. Note=Localized at tight junctions of both epithelial and endothelial cells.
      PTM: N-glycosylated.
      SIMILARITY: SwissProt: Q9Y624 ## Belongs to the immunoglobulin superfamily. & Contains 2 Ig-like V-type (immunoglobulin-like) domains.
