A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals. Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix. There are three major types of cell junctions: adherens junctions, desmosomes and hemidesmosomes (anchoring junctions); gap junctions (communicating junction); tight junctions (occluding junctions).
