Abstract

Septins are involved in many important cellular processes, and septin dysfunction has been implicated in various pathologies, such as cancer. Like other components of the cytoskeleton -F-actin, microtubules, and intermediate filaments-septins can self-assemble into filaments and higher-order structures. These non-polar filaments are assembled from complex and variable multimeric building blocks. Septins exhibit a distinct preference for interacting with actin and microtubule structures, particularly at the interface with cellular membrane. Although they are crucial for many vital cellular functions and are frequently observed at prominent cellular structures like stress fibers, cilia, and neuronal processes, our understanding of the regulation of septin filament dynamics and the organized assembly of higher-order structures remains limited. However, recent insights into the architecture of septin filaments, the structure of crucial septin domains, and their interactions with other cellular components (F-actin, microtubules, membranes) and regulatory proteins may now pave the way for rapid progress.

哺乳动物细胞中的蛋白酶动力学和组织结构
七联蛋白参与了许多重要的细胞过程,七联蛋白功能障碍与癌症等多种病症有关。与细胞骨架的其他成分(F-肌动蛋白、微管和中间丝)一样,七肽也能自我组装成丝和高阶结构。这些非极性细丝由复杂多变的多聚体构建模块组装而成。七肽表现出与肌动蛋白和微管结构相互作用的独特偏好,尤其是在与细胞膜的界面上。虽然它们对许多重要的细胞功能至关重要,而且经常在应力纤维、纤毛和神经元过程等突出的细胞结构中观察到它们的存在,但我们对隔膜蛋白丝动态调控和高阶结构有组织组装的了解仍然有限。不过,最近我们对 septin 细丝的结构、关键 septin 结构域的结构以及它们与其他细胞成分(F-肌动蛋白、微管、膜)和调控蛋白的相互作用有了深入的了解,这可能会为我们取得快速进展铺平道路。
