WAVE 调节复合体 (WRC) 将信息从 Rac GTPase 传输至肌动蛋白成核剂 Arp2/3 复合体。我们以多种形式重建了重组人和果蝇 WRC,并表明它们对 Arp2/3 复合物没有活性,但可以通过核苷酸依赖性方式被 Rac 激活。我们的观察确定了 WAVE 抑制所需的核心成分,调和了相互矛盾的现有机制,并揭示了 WAVE/WASP 家族的共同监管原则。
The WAVE Regulatory Complex (WRC) transmits information from the Rac GTPase to the actin nucleator, Arp2/3 complex. We have reconstituted recombinant human and Drosophila WRC in several forms and shown that they are inactive toward Arp2/3 complex, but can be activated by Rac in nucleotide dependent fashion. Our observations identify core components needed for WAVE inhibition, reconcile contradictory existing mechanisms and reveal common regulatory principles for the WAVE/WASP family.
