Abstract
A key problem in the cell cycle is understanding what brings about the initiation of DNA replication and how this is linked with global cell cycle controls. The fission yeast gene cdc18 is required for DNA replication and is transcriptionally activated by the cdc10/res1/res2 control acting at START in late G1. We show here that overexpressing cdc18 is able to bring about repeated rounds of DNA synthesis in the absence of mitosis and of continuing protein synthesis. The level of the cdc18-encoded protein p65cdc18 is periodic in the cell cycle, peaking at the G1 to S phase transition, and p65cdc18 is located in the nucleus when cdc18 is overexpressed. We propose that p65cdc18 acts at the initiation of DNA replication and plays a major role in controlling the onset of S phase.
