细胞皮层作为细胞外环境/细胞膜与下面的细胞骨架和细胞质之间的关键联系。在许多细胞中,细胞皮层由Ezrin、Radixin和Moesin(ERM)蛋白组织和维持,其具有与质膜和丝状肌动蛋白两者相互作用的能力。虽然这种膜-细胞骨架连接功能对细胞皮层的稳定性至关重要,但最近的研究表明,这只是ERMs在许多细胞中所起作用的一部分。除了它们在结合丝状肌动蛋白中的作用之外,ERMs还通过它们结合跨膜受体并将它们连接到下游信号传导组分的能力来调节信号传导途径。在这篇综述中,我们讨论了最近在各种细胞中的证据表明,ERMs作为支架,以促进有效的信号转导的质膜的细胞质面。
The cell cortex serves as a critical nexus between the extracellular environment/cell membrane and the underlying cytoskeleton and cytoplasm. In many cells, the cell cortex is organized and maintained by the Ezrin, Radixin and Moesin (ERM) proteins, which have the ability to interact with both the plasma membrane and filamentous actin. Although this membrane-cytoskeletal linkage function is critical to stability of the cell cortex, recent studies indicate that this is only a part of what ERMs do in many cells. In addition to their role in binding filamentous actin, ERMs regulate signaling pathways through their ability to bind transmembrane receptors and link them to downstream signaling components. In this review we discuss recent evidence in a variety of cells indicating that ERMs serve as scaffolds to facilitate efficient signal transduction on the cytoplasmic face of the plasma membrane.
