复制许可制度的作用是确保基因组的任何部分在单个细胞周期内复制不超过一次。利用爪蟾卵提取物进行的实验表明,该许可系统由RLF-M和RLF-B两部分组成。尽管RLF-B的功能尚不清楚,但RLF-M已被证明由MCM/P1家族蛋白的所有六个成员组成,这似乎是许可系统的结构组成部分。起源识别复合体(ORC)和Cdc6/Cdc18在许可反应发生之前需要在染色质上,尽管它们本身不是许可系统的组成部分。细胞周期事件和周期蛋白依赖性蛋白激酶(Cdks)似乎也参与控制许可系统,以确保每个细胞周期DNA复制一次。本综述的主题是详细介绍我们目前对许可制度的理解以及它与细胞周期机制的其他组成部分相互作用的方式。
The replication licensing system acts to ensure that no section of the genome is replicated more than once in a single cell cycle. Experiments using Xenopus egg extracts have revealed that the licensing system consists of two components, named RLF-M and RLF-B. Whereas the function of RLF-B is still unclear, RLF-M has been shown to consist of all six members of the MCM/P1 family proteins, which appear to be the structural component of the licensing system. The origin recognition complex (ORC) and Cdc6/Cdc18 are needed on chromatin before the licensing reaction can take place, although they are not themselves components of the licensing system. Cell cycle events and cyclin-dependent protein kinases (Cdks) also seem to be involved in controlling the licensing system to ensure once per cell cycle DNA replication. The subject of this review is to detail our current understanding of the licensing system and the way that it interacts with other components of the cell cycle machinery.
