Explain tight junctions
Tight junctions are areas where the membranes of two adjacent cells join together to form a barrier. The cell membranes are connected by strands of transmembrane proteins such as claudins and occludins. Tight junctions bind cells together, prevent molecules from passing in between the cells, … See more Tight junctions have several different functions. Their most important functions are to help cells form a barrier that prevents molecules from getting through, and to stop proteins in the cell membrane from moving around. … See more This diagram depicts a tight junction between cells and also provides examples of proteins found in the junction.
