Abstract

Integrin-mediated activation of Cdc42 is essential for cell polarization, whereas the integrin adaptor protein Cas is required for cell migration during wound healing. After phosphorylation on tyrosine residues, Cas recruits the adaptor proteins Crk and Nck to execute integrin-mediated signals. However, the mechanisms leading to Cdc42 activation and its relationship with Cas, Crk and Nck have not been elucidated clearly. In the present study, we demonstrate that Cas utilizes Nck2 to activate Cdc42 and induce cell polarization in response to wounding. By contrast, Cas recruits CrkII to activate Rac1 and promote the extension of cell protrusions needed for cell motility. These results indicate that Cas utilizes Nck2 and CrkII in a coordinated set of distinct pathways leading to cell migration.
