Adherens junctions are specialized structures that connect adjacent cells in tissues, helping to maintain their shape and integrity. They are primarily composed of proteins called cadherins, which bind to each other across the cell membranes, creating a strong adhesion between cells. This connection is crucial for the formation of tissues and plays a significant role in cellular signaling. These junctions are often found in epithelial tissues, where they help to form a continuous layer of cells. Additionally, adherens junctions are linked to the cytoskeleton, providing mechanical support and enabling cells to respond to changes in their environment.
