... cadherin interacts with F-actin via b-catenin and a-catenin; b-catenin binds to cadherin and a-catenin, which in turn interacts with F-actin (Fig. 3A) [24]. Thus b-catenin plays a pivotal role in the ... cadherin–catenin complexes within each cell and by cadherin–cadherin interactions between the two cells. The interkinetic cells adhere to each other via cadherin–catenin c...
