How does the structure of a tight junction differ from that of an anchoring junction?
What will be an ideal response?
At a tight junction the lipid portions of the opposing plasmalemmas are tightly bound together by interlocking membrane proteins, providing the strongest of intercellular connections; at a anchoring junction, the two plasmalemmas remain distinct but are powerfully attached by CAMs (cell adhesion molecules) and a layer of proteoglycans (intercellular cement), with a dense area of layered proteins inside each plasmalemma reinforcing the junction and binding it to the cell's cytoskeleton.
