Depolymerized ADP-actin monomers must be recharged with ATP for new rounds of filament assembly. Here the authors show that cyclase-associated protein (CAP) catalyzes actin nucleotide exchange in vivo and their CAP–actin complex structure reveals the molecular mechanism of CAP-mediated actin nucleotide exchange.
