摘 要:细胞周期是一种非常复杂和精细的调节过程,有大量调节蛋白参与其中。此过程的核心是细胞周期依赖性蛋白激酶(CDKs)。CDKs的激活又依赖于另一类呈细胞周期特异性或时相性表达的细胞周期蛋白(cyclins),而CDKs调节的关键步骤是细胞周期检查点。PLKs是多种细胞周期检查点的主要调节因子,Aurora蛋白激酶主要在细胞有丝分裂期起作用。本文就上述因素在细胞周期进程中的作用作一综述。

Abstract: The cell cycle is a complex and elaborate process involving numerous regulatory proteins as directors. Central to this process are the cyclin-dependent kinases (CDKs), which are activated in a cyclin-dependent manner at special points of the cell cycle. Cyclin protein levels rise and fall during the cell cycle and in the way they periodically activate CDKs. Furthermore, the cell cycle checkpoint is also discussed as a key process in the regulation of CDKs. PLKs are important mediators for various cell cycle checkpoints, while Aurora kinases have emerged as essential regulators of cell division. Here, we reviewed the effects of above factors on cell cycle regulation.
Key words: cell cycle; regulation; cell cycle checkpoint
