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.
Epithelial cells are held together by strong anchoring (zonula adherens) junctions. The adherens junction lies below the tight junction (occluding junction). In the gap (about 15-20nm) between the two cells, there is a protein called cadherin-a cell membrane glycoprotein.(The type of cadherin found here is E-cadherin). occluding junctions (zonula occludens or tight junctions). 2  adhering junctions (zonula adherens). 3  desmosomes (macula adherens). 4  There are also ' hemidesmosomes ' that lie on the basal membrane, to help stick the cells to the underlying basal lamina.
