In higher eukaryotes, the formation of branched actin filament networks generated by Arp2/3 complex is crucial to a plethora of cellular processes, like cell edge protrusion, cell-cell adhesion, phagocytosis or membrane trafficking. We are dissecting the molecular regulation of these and related processes such as host-pathogen interaction using CRISPR/Cas9-mediated genome editing. We are characterizing derived, mutant cell lines with respect to essential, functional parameters and including various, advanced imaging approaches.

In this talk, I will focus on the molecular regulation of lamellipodium protrusion, and provide examples for how CRISPR/Cas9-edited cell lines can be employed to study the biochemistry, individual mutations or the gene dose of selected, Arp2/3 complex-dependent actin assembly complexes.
