cell shape
The adherens junction functions to connect epithelial cells and maintain their polarized architecture. The geometry of the adherens junction, and consequently the shape of a cell, appears to reach an energetically favorable state.
Cadherins within the adherens junction are necessary for cells to achieve this state. Interactions between the actin cytoskeleton and the adherens junction are required for certain cell shape changes.
