Abstract

We have cloned a suppressor of a temperature-sensitive rad52 allele and found it to be a mutation in PUP1, a gene encoding a proteasome subunit o the 20s proteasome. This identity prompted us to examine the interrelationship among PUP1, RAD52, SRS2 and RAD6 because srs2 mutations not only suppress some rad52 mutations but also found that while srs2 suppresses the UV sensitivity if rad6 in the presence of RAD52, srs2 cannot suppress rad6 when the temperature-sensitive allele of rad52 is present. This inability of srs2 to suppress rad6 is irrespective of the incubation temperature-sensitive rad52 mutation.
