A transposon mutagenized allele of CYR1 results in a 90% increase in chronological life-span.

Other phenotypes: Null mutant arrest at G1 phase is rescued by exogenous cAMP [pubmed]. A transposon mutagenized allele of CYR1 results in resistance to hydrogen peroxide, and resistance to heat shock [pubmed]. Deletion of SOD2 fails to prevent the increased stationary phase survival caused by mutation of CYR1 [pubmed].
