Cyclin-dependent kinases (CDKs) activate the firing of replication origins during the S phase of the cell cycle. They also block re-initiation of DNA replication within a single cell cycle, by preventing the assembly of prereplicative complexes at origins. We show here that, in budding yeast, CDKs exclude the essential prereplicative-complex component Mcm4 from the nucleus. Although origin firing can be triggered by the B-type cyclins only, both G1-phase and B-type cyclins cause exit of Mcm4 from the nucleus. These results suggest that G1 cyclins may diminish the cell's capacity to assemble prereplicative complexes before B-type cyclins trigger origin firing during S phase.
