Cyclin-dependent kinases (CDKs) are absolutely required for DNA replication in eukaryotic cells. CDKs are thought to activate one or more replication factors, but the identities of these proteins are unknown. Here we describe fission yeast Drc1, a protein required for DNA replication that is phosphorylated by Cdc2. Drc1 depletion leads to catastrophic mitotic divisions with incompletely replicated DNA, indicating that Drc1 is required for DNA synthesis and S-M replication checkpoint control. Drc1 associates with Cdc2 and is phosphorylated at the onset of S phase when Cdc2 is activated. Mutant Drc1 that lacks CDK phosphorylation sites is nonfunctional and fails to interact with Cut5 replication factor. These data suggest that Cdc2 promotes DNA replication by phosphorylating Drc1 and regulating its association with Cut5.
