细胞骨架组织蛋白WASP和WAVE家族的研究进展。所有真核细胞都需要重组它们的肌动蛋白细胞骨架来改变形状、分裂、移动和吸收生存所需的营养。Wiskott-Aldrich综合征蛋白(WASP)和WASP家族verprolin同源蛋白(WAVE)家族蛋白是真核生物中发现的基本的肌动蛋白-细胞骨架重组蛋白。跨物种的保守功能是接收来自rho家族小gtpase的上游信号并将其发送激活Arp2/3复合物,导致快速的肌动蛋白聚合,这对细胞内吞作用和细胞运动等细胞过程至关重要。分子和细胞生物学研究已经确定了一系列与WASP和WAVE蛋白结合的调节分子,并使它们在不同的细胞位置发挥不同的作用。利用模式生物进行遗传研究也提高了我们对WASP和wave家族蛋白如何塑造复杂组织结构的理解。目前的努力集中在整合这些分子信息,以绘制一个统一的图像,肌动蛋白细胞骨架如何在单个细胞中动态地工作,以建立多细胞组织。
A review of the cytoskeleton-organizing WASP and WAVE family proteins. All eukaryotic cells need to reorganize their actin cytoskeleton to change shape, divide, move, and take up nutrients for survival. The Wiskott-Aldrich syndrome protein (WASP) and WASP-family verprolin-homologous protein (WAVE) family proteins are fundamental actin-cytoskeleton reorganizers found throughout the eukaryotes. The conserved function across species is to receive upstream signals from Rho-family small GTPases and send them to activate the Arp2/3 complex, leading to rapid actin polymerization, which is critical for cellular processes such as endocytosis and cell motility. Molecular and cell biological studies have identified a wide array of regulatory molecules that bind to the WASP and WAVE proteins and give them diversified roles in distinct cellular locations. Genetic studies using model organisms have also improved our understanding of how the WASP- and WAVE-family proteins act to shape complex tissue architectures. Current efforts are focusing on integrating these pieces of molecular information to draw a unified picture of how the actin cytoskeleton in a single cell works dynamically to build multicellular organization.
