Figure 11.14Attachment of actin filaments to adherens junctions

Cell-cell contacts at adherens junctions are mediated by cadherins, which serve as sites of attachment of actin bundles. In sheets of epithelial cells, these junctions form a continuous belt of actin filaments around each cell. The cadherins are transmembrane proteins that bind β-catenin to their cytoplasmic domains. β-catenin interacts with α-catenin, which serves as a link to actin filaments.
