Cdc7/Dbf4 is a protein kinase that is required for the initiation of DNA replication in eukaryotes. Recent work has provided new clues to the role that Cdc7/Dbf4 plays in this process. A range of other observations suggest that Cdc7/Dbf4 also plays another, less well characterized, role in checkpoint function and in the maintenance of genomic integrity. In this review we attempt to bring together new information to explain how Cdc7/Dbf4 may perform these two distinct functions.
Cdc7/Dbf4是一种蛋白激酶,真核生物DNA复制起始时需要它。最近的研究为Cdc7/Dbf4在此过程中所起的作用提供了新线索。一系列其他观察结果表明,Cdc7/Dbf4在检查点功能和基因组完整性维持方面也发挥着另一个特征不太明确的作用。在本综述中,我们试图整合新信息,以解释Cdc7/Dbf4如何执行这两种不同的功能。
