tight juncÂ·tion. An intercellular junction between epithelial cells in which the outer leaflets of lateral cell membranes fuse to form a variable number of parallel interweaving strands that greatly reduce transepithelial permeability to macromolecules, solutes, and water through the paracellular route.
Some of the transmembrane glycoproteins are cadherins. Adherens junctions called focal contacts can join a cell to the ECM, primarily through fibronectin receptors. Tight junctions leave no space between plasma membranes of adjacent cells to prevent the movement of molecules across cell layers.he carbohydrate groups of N-CAMs and caherins determine the strength and specificity of cell-cell recognition and adhesion. N-CAMs have repeating chains of negatively charged sialic acid which changes during development. Vesicles with N-CAMs having little sialic acid bind tighter than those with large amounts.
