Abstract     Endothelial cell-cell junctions play an important role in vascular hemostasis. Two junctional proteins, namely JAM-l and VE-cadherin; are localized at tight and adherens and junctions, respectively. While VE-cadherin is only expressed in endothelial cells, JAM-1 is also expressed in epithelial cells. Here, we will focus on the role of JAM-1 in the molecular architecture of endothelial tight junctions. The extracellular domain of JAM-1 can form dimers and mediate homophilic binding, The intracellular domain (and in particular a PDZ-binding motif) enables JAM-1 to interact with structural and signaling proteins, such as ZO-1, cingulin, CASK, and AF-6. Study of the molecular interactions of JAM-1 may help understand the functional role of JAM-1 in the control of paracellular permeability and leukocyte transmigration.
