Ezh2, a polycomb group protein, is known to function in histone methylation, thereby regulating gene expression. However, in a recent study by Su et al., the Ezh2-containing complex has been given an additional role in cellular regulation. Cytosolic Ezh2 methyltransferase complexes were shown to associate with Vav1 and control receptor-induced actin polymerization and proliferation in a methylation-dependent manner. Overall, these findings implicate lysine methylation as a posttranslational modification crucial for receptor-mediated signal transduction events.
