Recent cadherin studies focusing on cellular signaling have shown that several pathways are activated by cadherin-mediated cell–cell contact. Cadherin-mediated contacts activate Rho family GTPases, regulate the availability of β-catenin to participate in Wnt signaling, and function in receptor tyrosine kinase signaling. Although different classical cadherins bind to the same cytosolic proteins via their cytoplasmic tails, one message that is clear from the recent literature is that downstream signals emanating from cadherin-mediated contacts are both cadherin-specific and cell-context-specific.
