Actin polymerization is a fundamental cellular process driving functions as diverse as cell migration, endocytosis and adhesion. To fulfill its various tasks in the cell, the assembly and disassembly of actin filaments has to be tightly regulated. Cortactin has been described as Arp2/3 activator stabilizing branches in dendritic actin filament networks. The characterization of cortactin KO cells has challenged this view, as lamellipodia formation e.g. was normal in the absence of cortactin. In this thesis, the potential functions of cortactin in migration, podosome formation and on Arp2/3 activation were explored. The observed migration defect in cortactin-deficient cells could be restored by overexpression of constitutively active Rho-GTPa...
