Anchoring Junctions. The main purpose of an anchoring junction is to hold cells together at a mass of proteins called a plaque. Anchoring junctions are made up of three different proteins: cadherins, which form homodimers with each other in the membranes of adjacent cells, and Î±-catenin and Î²-catenin.t is composed of a pair of E-cadherins. Anchoring junctions are found in tissues that stretch a lot, such as muscles and skin. Anchoring junctions also transduce signals in and out of cells.
