EpCAM is an unconventional epithelia-specific cell–cell adhesion molecule, that is mutated in the majority of cases of Congenital Tufting Enteropathy. Here the authors show that loss of EpCAM causes a concentration of contractile activity at tricellular junctions, leading to aberrant apical domain and tight junction displacement.
