Activation of tyrosine kinase receptors in epithelial cells results in the rapid disassembly of E-cadherin-mediated cell–cell adhesions. New research has identified Hakai, an E3-ubiquitin-ligase related to Cbl that binds E-cadherin in a tyrosine phosphorylation-dependent manner. By promoting the endocytosis and dynamic recycling or destruction of E-cadherin complexes, Hakai may control epithelial–mesenchymal transitions under physiological and pathological conditions.
