Previous studies have proposed that Cbl is also a positive regulator of CrkL-C3G signalling, which leads to Rap1 activation. However, there is a lack of genetic evidence for a physiological function of Cbl in regulating this pathway. Here, we show that Cbl deficiency results in enhanced activation of Rap1. Cbl was shown to promote the ubiquitylation of CrkL without any apparent effect on its stability. Remarkably, the membrane translocation of C3G, its association with CrkL, and the guanine-nucleotide exchange activity of C3G were all increased in Cbl(-/-) thymocytes. Consistent with a function of Rap1 in integrin activation, enhanced integrin-mediated cell adhesion was also seen in Cbl(-/-) thymocytes. Thus, Cbl negatively regulates Rap1 activation, probably through a proteolysis-independent E3-ubiquitin-ligase activity of Cbl that modulates protein-protein interactions."xsd:string |
