Abstract

Cytokinesis, the process by which the cytoplasm divides to generate two daughter cells after mitosis, is a crucial stage of the cell cycle. Successful cytokinesis must be coordinated with chromosome segregation and requires the fine orchestration of several processes, such as constriction of the actomyosin ring, membrane reorganization, and, in fungi, cell wall deposition. In Saccharomyces cerevisiae, commonly known as budding yeast, septins play a pivotal role in the control of cytokinesis by assisting the assembly of the cytokinetic machinery at the division site and controlling its activity. Yeast septins form a collar at the division site that undergoes major dynamic transitions during the cell cycle. This review discusses the functions of septins in yeast cytokinesis, their regulation and the implications of their dynamic remodelling for cell division.

芽殖酵母细胞分裂的蛋白酶组织和动力学
细胞分裂是有丝分裂后细胞质分裂生成两个子细胞的过程,是细胞周期的关键阶段。成功的细胞分裂必须与染色体分离相协调,并且需要对多个过程进行精细的协调,例如肌动蛋白环的收缩、膜的重组,以及真菌中细胞壁的沉积。在通常被称为芽殖酵母的酿酒酵母中,隔膜蛋白在细胞分裂的控制过程中扮演着关键的角色,它协助细胞分裂机械在分裂部位的组装并控制其活动。酵母隔膜在分裂部位形成一个环,在细胞周期中会发生重大的动态变化。这篇综述讨论了隔膜在酵母细胞分裂中的功能、它们的调控以及它们的动态重塑对细胞分裂的影响。

期刊介绍: Journal of Fungi (ISSN 2309-608X) is an international, peer-reviewed scientific open access journal that provides an advanced forum for studies related to pathogenic fungi, fungal biology, and all other aspects of fungal research. The journal publishes reviews, regular research papers, and communications in quarterly issues. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on paper length. Full experimental details must be provided so that the results can be reproduced.
