An emerging aspect of regulation is the incorporation of subunit isoforms into the Arp2/3 complex. Specifically, both ArpC5 subunit isoforms, ArpC5 and ArpC5L, have been reported to fine-tune nucleation activity and branch junction stability. We have combined reverse genetics and cellular structural biology to describe how ArpC5 and ArpC5L differentially affect cell migration. Both define the structural stability of ArpC1 in branch junctions and, in turn, by determining protrusion characteristics, affect protein dynamics and actin network ultrastructure. ArpC5 isoforms also affect the positioning of members of the Ena/Vasodilator-stimulated phosphoprotein (VASP) family of actin filament elongators, which mediate ArpC5 isoform–specific effects on the actin assembly level. Our results suggest that ArpC5 and Ena/VASP proteins are part of a signaling pathway enhancing cell migration.</jats:p>","lang":"eng"}],"date_created":"2023-01-23T07:26:42Z","department":[{"_id":"FlSc"},{"_id":"EM-Fac"}],"publisher":"American Association for the Advancement of Science","day":"20","article_processing_charge":"No","acknowledged_ssus":[{"_id":"ScienComp"},{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"EM-Fac"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"file":[{"relation":"main_file","file_size":1756234,"access_level":"open_access","checksum":"ce81a6d0b84170e5e8c62f6acfa15d9e","date_created":"2023-01-23T07:45:54Z","content_type":"application/pdf","success":1,"date_updated":"2023-01-23T07:45:54Z","file_name":"2023_ScienceAdvances_Faessler.pdf","file_id":"12335","creator":"dernst"}],"ddc":["570"],"article_number":"add6495","acknowledgement":"We would like to thank K. von Peinen and B.
