有丝分裂和细胞质分裂过程中导致染色体分离的事件的适当时机对于防止非整倍体是必不可少的,而这些过程中的缺陷可能有助于肿瘤的发生。关键的有丝分裂调节因子通过泛素化和蛋白酶体介导的降解来控制。后期促进复合体或环小体(APC/C)是一种E3泛素连接酶,在有丝分裂细胞周期的调控中起着至关重要的作用,特别是在有丝分裂后期开始和有丝分裂退出期间。辅激活蛋白、抑制蛋白、蛋白激酶和磷酸酶与APC/C相互作用,在时间和空间上控制其活性,从而确保有丝分裂事件的准确定时。
The appropriate timing of events that lead to chromosome segregation during mitosis and cytokinesis is essential to prevent aneuploidy, and defects in these processes can contribute to tumorigenesis. Key mitotic regulators are controlled through ubiquitylation and proteasome-mediated degradation. The Anaphase-Promoting Complex or Cyclosome (APC/C) is an E3 ubiquitin ligase that has a crucial function in the regulation of the mitotic cell cycle, particularly at the onset of anaphase and during mitotic exit. Co-activator proteins, inhibitor proteins, protein kinases and phosphatases interact with the APC/C to temporally and spatially control its activity and thus ensure accurate timing of mitotic events.
