Formatted abstract
These findings demonstrate the role of α-catenin in cadherin-based adhesion and mechanotransduction, in different mechanical contexts. Bead-twisting measurements in conjunction with imaging, and the use of different cell lines and α-catenin mutants reveal that the acute, local mechanical manipulation of cadherin bonds triggers vinculin and actin recruitment to cadherin adhesions, in an actin- and α-catenin-dependent manner. The modest effect of α-catenin on two-dimensional binding affinities of cell surface cadherins further suggests that force-activated adhesion strengthening is due to enhanced cadherin/cytoskeletal interactions rather than to α-catenin-dependent affinity modulation. Complementary investigations of cadherin-based rigidity sensing also suggest that, although α-catenin alters traction force generation, it is not the sole regulator of cell contractility on compliant, cadherin-coated substrata.
