Arp2/3 复合物协调细胞质和膜之间界面处分支肌动蛋白网络的形成。尽管人们普遍认为这些网络可用于支架、在膜界面处产生推力和描绘区域,但直到最近才发现分支肌动蛋白网络具有机械敏感性,从而赋予它们特殊的性质。在这里,我们讨论了我们在理解 Arp2/3 生成的肌动蛋白网络如何响应负载力方面的最新进展,从而允许细胞以响应和可调节的方式产生推力,以影响细胞过程,如迁移、侵袭、吞噬、粘附,甚至核和 DNA 损伤修复。
The Arp2/3 complex orchestrates the formation of branched actin networks at the interface between the cytoplasm and membranes. Although it is widely appreciated that these networks are useful for scaffolding, creating pushing forces and delineating zones at the membrane interface, it has only recently come to light that branched actin networks are mechanosensitive, giving them special properties. Here, we discuss recent advances in our understanding of how Arp2/3-generated actin networks respond to load forces and thus allow cells to create pushing forces in responsive and tuneable ways to effect cellular processes such as migration, invasion, phagocytosis, adhesion and even nuclear and DNA damage repair.
