Abstract
How cells assemble distinct actin networks from shared cytoplasmic components remains an important unresolved question. In this issue, Wirshing et al. (2023. J. Cell Biol.https://doi.org/10.1083/jcb.202209105) demonstrate how capping protein and formin competition for actin filament barbed ends controls the assembly of branched and linear actin networks.
