Abstract: We have identified a cell cycle delay in Saccharomyces cerevisiae RNase MRP mutants. Mutants delay with large budded cells, dumbbell-shaped nuclei, and extended spindles characteristic of "exit from mitosis" mutants. In accord with this, a RNase MRP mutation can be suppressed by overexpressing the polo-like kinase CDC5 or by deleting the B-type cyclin CLB1, without restoring the MRP-dependent rRNA-processing step. In addition, we identified a series of genetic interactions between RNase MRP mutations and mutations in CDC5, CDC14, CDC15, CLB2, and CLB5. As in most "exit from mitosis" mutants, levels of the Clb2 cyclin were increased. The buildup of Clb2 protein is not the result of a defect in the release of the Cdc14 phosphatase from the nucleolus, but rather the result of an increase in CLB2 mRNA levels. These results indicate a clear role of RNase MRP in cell cycle progression at the end of mitosis. Conservation of this function in humans may explain many of the pleiotropic phenotypes of cartilage hair hypoplasia.
