Adhesion belts between epithelial cells in the small intestine.

This belt like anchoring junction encircles each of the interacting cells. Its most obvious feature is a contractile bundle of actin filaments running along the cytoplasmic surface of the junctional plasma membrane. The actin filaments are joined from cell to cell by transmembrane linker proteins (cadherins), whose extracellular domain binds to the extracellular domain of an identical cadherin molecule on the adjacent cell.
