An adherens junction is a type of cell junction that helps cells stick together, forming strong connections in tissues. These junctions are primarily found in epithelial and cardiac tissues, where they play a crucial role in maintaining the structural integrity of the tissue. They are composed of proteins, including cadherins, which link the cytoskeleton of one cell to that of another. In addition to providing mechanical support, adherens junctions also facilitate communication between cells. They help transmit signals that can influence cell behavior, such as growth and differentiation. This makes them important for processes like tissue development and repair, as well as maintaining the overall function of organs like the heart and skin.
