Arp2/3 complex forms branched actin networks that drive cell and organelle motility. Here, authors show that Coro7 targets branch junctions by binding Arp2/3 complex and actin filaments, promoting debranching, and supporting ER–Golgi transport.

Cytoplasmic dynein is a minus-end-directed microtubule-based motor that transports a wide range of cargoes, including organelles, RNAs, protein complexes and viruses. How a single motor can interact with and traffic such different cargoes has been unclear. Recent studies indicate how adaptor proteins, which can both activate dynein and link it to cargo, play an important role in this process.
