Abstract

Successful DNA replication requires intimate coordination with cell-cycle progression. Prior to DNA replication initiation in S phase, a series of essential preparatory events in G phase ensures timely, complete, and precise genome duplication. Among the essential molecular processes are regulated transcriptional upregulation of genes that encode replication proteins, appropriate post-transcriptional control of replication factor abundance and activity, and assembly of DNA-loaded protein complexes to license replication origins. In this chapter we describe these critical G events necessary for DNA replication and their regulation in the context of both cell-cycle entry and cell-cycle progression.

摘要

成功的 DNA 复制需要与细胞周期进程密切协调。在 S 期 DNA 复制起始之前,G 期的一系列必要准备事件确保了基因组的及时、完整和精确复制。其中必不可少的分子过程包括:调节复制蛋白编码基因的转录上调、适当的复制因子丰度和活性的转录后控制,以及装载 DNA 的蛋白质复合物的组装以许可复制起点。在本章中,我们将描述这些对于 DNA 复制至关重要的 G 期事件及其在细胞周期进入和细胞周期进程中的调控。
