A temperature-sensitive (ts) mutant retains the function of a gene at a low (permissive) temperature but not at a high (nonpermissive) temperature. Arg-DHFR, a dihydrofolate reductase bearing an amino-terminal (N-terminal) arginine, is long-lived in the yeast Saccharomyces cerevisiae, even though arginine is a destabilizing residue in the N-end rule of protein degradation. A ts derivative of Arg-DHFR was identified that is long-lived at 23°C but rapidly degraded by the N-end rule pathway at 37°C. Fusions of ts Arg-DHFR to either Ura3 or Cdc28 of S. cerevisiae confer ts phenotypes specific for these gene products. Thus, Arg-DHFR^ts is a heat-inducible degradation signal that can be used to produce ts mutants without a search for ts mutations.
