Summary

The product of the PHO85 gene, which encodes one of the negative regulatory factors of the PHO system in Saccharomyces cerevisiae, shows significant amino acid sequence homology with the CDC28 protein kinase. However, overexpressing PHO85 did not suppress the temperature sensitive phenotype of the cdc28-1 mutation. The nucleotide sequence of the PHO85 gene strongly suggests the presence of an intron near the sequence encoding the N-terminal region.
