A barbed end interference mechanism reveals how capping protein promotes nucleation in branched actin networks
The assembly of branched actin networks depends on the heterodimeric capping protein CP/CapZ. Combining cryoEM, in vitro reconstitution and cell biological assays, the authors show that CP not only prevents actin filament elongation but also selectively masks actin filament ends to promote nucleatio...

| Sumario: | The assembly of branched actin networks depends on the heterodimeric capping protein CP/CapZ. Combining cryoEM, in vitro reconstitution and cell biological assays, the authors show that CP not only prevents actin filament elongation but also selectively masks actin filament ends to promote nucleation. |
