Abstract

Saccharomyces cerevisiae cells containing mutations in the cell-division-cycle gene CDC46 arrest with a large bud and a single nucleus with unreplicated DNA at the non-permissive temperature. This G1/S arrest, together with the increased rates of mitotic chromosome loss and recombination phenotype, suggests that these mutants are defective in DNA replication. The subcellular localization of the CDC46 protein changes with the cell cycle; it is nuclear between the end of M phase and the G1/S transition but is cytoplasmic in other phases of the cell cycle. Here we show that CDC46 is identical to MCM5, based on complementation analysis of the mcm5-1 and cdc46-1 alleles, complementation of the minichromosome maintenance defect of mcm5-1 by CDC46, and the genetic linkage of these two genes. Like mcm5-1, cdc46-1 and cdc46-5 also show a minichromosome maintenance defect thought to be associated with DNA replication initiation at autonomously replicating sequences. Taken together, these observations suggest that CDC46/MCM5 acts during a very narrow window at the G1/S transition or the beginning of S phase by virtue of its nuclear localization to effect the initiation of DNA replication at autonomously replicating sequences.
