A mutation in the gene IRA] (formerly called PPI)I) was originally characterized as a deficiency of a phosphoprotein phosphatase. The IRA] gene has been cloned and sequenced. A large open reading frame (8,817 base pairs) which can encode a protein of 2,938 amino acids was found. Northern (RNA) blot analysis detected a message of about 10 kilobases, and nuclease Si protection demonstrated mRNA start points at 97 and 98 base pairs upstream from the putative initiator ATG codon. Disruption of the IRA) gene resulted in sensitivity to nitrogen starvation and heat shock. Diploids homozygous for the disrupted IRA] gene were deficient in sporulation. Disruption of the IRA) gene suppressed the lethality of the cdc25 mutation but did not suppress the lethality of either the rasl ras2 or the cyri mutations. Deficiency of the phosphoprotein phosphatase was not reproducible in the disruption mutant of the IRA) gene. Moreover, the iral mutant showed an increased level of cyclic AMP. Our results suggest that the IRA) protein inhibits the function of the RAS proteins in a fashion antagonistic to the function of the CDC25 protein in the RAS-cyclic AMP pathway in Saccharomyces cerevisiae.
