摘要：
The Arp2/3 complex is a powerful nucleator of actin filaments when activated. A recent study has now revealed that this complex is not only subject to positive control but that there also exists a brake on its activity. This brake can suppress both the basal activity of the Arp2/3 complex as well as its activation by nucleation-promoting factors.
