In Saccharomyces cerevisiae, the ubiquitin-like protein Rub1p (related to ubiquitin 1 protein) covalently attaches to the cullin protein Cdc53p (cell division cycle 53 protein), a subunit of a class of ubiquitin E3 ligases named SCF (Skp1-Cdc53-F-box protein) complex. We identified Rtt101p (regulator of Ty transposition 101 protein, where Ty stands for transposon of yeast), initially found during a screen for proteins to confer retrotransposition suppression, and Cul3p (cullin 3 protein), a protein encoded by the previously uncharacterized open reading frame YGR003w, as two new in vivo targets for Rub1p conjugation. These proteins show significant identity with Cdc53p and, therefore, are cullin proteins. Modification of Cul3p is eliminated by deletion of the Rub1p pathway through disruption of either RUB1 or its activating enzyme ENR2 / ULA1. The same disruptions in the Rub pathway decreased the percentage of total Rtt101p that is modified from approx. 60 to 30%. This suggests that Rtt101p has an additional RUB1 - and ENR2 -independent modification. All modified forms of Rtt101p and Cul3p were lost when a single lysine residue in a conserved region near the C-terminus was replaced by an arginine residue. These results suggest that this lysine residue is the site of Rub1p-dependent and -independent modifications in Rtt101p and of Rub1p-dependent modification in Cul3p. An rtt101 Delta strain was hypersensitive to thiabendazole, isopropyl ( N -3-chlorophenyl) carbamate and methyl methanesulphonate, but rub1 Delta strains were not. Whereas rtt101 Delta strains exhibited a 14-fold increase in Ty1 transposition, isogenic rub1 Delta strains did not show statistically significant increases. Rtt101K791Rp, which cannot be modified, complemented for Rtt101p function in a transposition assay. Altogether, these results suggest that neither the RUB1 -dependent nor the RUB1 -independent form of Rtt101p is required for Rtt101p function. The identification of additional Rub1p targets in S. cerevisiae suggests an expanded role for Rub in this organism.
