Cellular junctions are complex, multiprotein cellular structures between adjacent cells or between cells and the extracellular matrix. These junctions allow contact and communication between cells and their environment, in addition to regulating tissue permeability and mediating intracellular signaling events. The functional and molecular components, as well as some of their unique features, of the following junctions are discussed: tight junctions, adherent junctions, desmosomes, gap junctions, hemidesmosomes, and focal adhesions.
