Non-junctional, homodimeric αE-catenin regulates membrane dynamics. In this model, there are two distinct populations of αE-catenin. At the AJ, αE-catenin associates with the CCC and mediates attachment to the actin cytoskeleton, either directly or indirectly. Near the membrane, a cytosolic pool of αE-catenin is created through dissociation from the CCC. This cytosolic pool has a high local concentration and can therefore form αE-catenin homodimers that are able to inhibit the Arp2/3 complex and thereby dampen membrane dynamics by preventing the formation of branched F-actin (Benjamin et al., 2010).
