Two new studies published in this issue of Developmental Cell by Derivery et al. and Gomez and Billadeau reveal that WASH (Wiskott-Aldrich syndrome protein and SCAR homolog) activates Arp2/3 on endosomes and plays a critical role in the fission of tubules that serve as transport intermediates during endosome sorting.
本期《发育细胞》杂志上发表的两项新研究，即德利维等人以及戈麦斯和比拉多所做的研究，揭示了WASH（威斯科特-奥尔德里奇综合征蛋白和SCAR同源物）在内体上激活Arp2/3，并在作为内体分选过程中运输中间体的小管裂变中起关键作用。
