SUMMARYCell division-cytokinesis-involves large-scale rearrangements of the entire cell. Primarily driven by cytoskeletal proteins, cytokinesis also depends on topological rearrangements of the plasma membrane, which are coordinated with nuclear division in both space and time. Despite the fundamental nature of the process, different types of eukaryotic cells show variations in both the structural mechanisms of cytokinesis and the regulatory controls. In animal cells and fungi, a contractile actomyosin-based structure plays a central, albeit flexible, role. Here, the underlying molecular mechanisms are summarized and integrated and common themes are highlighted.
摘要细胞分裂-胞质分裂涉及整个细胞的大规模重排。胞质分裂主要由细胞骨架蛋白驱动,但也依赖于质膜的拓扑重排,这种重排与核分裂在空间和时间上相协调。尽管这一过程具有基础性,但不同类型的真核细胞在胞质分裂的结构机制和调控控制方面存在差异。在动物细胞和真菌中,收缩的肌动球蛋白基结构起着核心作用,尽管这种作用具有一定的灵活性。在这里,总结并整合了潜在的分子机制,并强调了共同的主题。
