PRE2

DOA3, PRG1, SRR2, proteasome core particle subunit beta 5, L000001484, YPR103W
Beta 5 subunit of the 20S proteasome; responsible for the chymotryptic activity of the proteasome

NOB1

YOR29-07, YOR056C
Protein involved in proteasomal and 40S ribosomal subunit biogenesis; required for cleavage of the 20S pre-rRNA to generate the mature 18S rRNA; cleavage is activated by Fun12p, a GTPase and translation initiation factor; relocalizes from nucleus to nucleolus upon DNA replication stress
Saccharomyces cerevisiae (S288c)

Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

Identification of the gal4 suppressor Sug1 as a subunit of the yeast 26S proteasome.

Rubin DM, Coux O, Wefes I, Hengartner C, Young RA, Goldberg AL, Finley D

The SUG1 gene of Saccharomyces cerevisiae encodes a putative ATPase. Mutations in SUG1 were isolated as suppressors of a mutation in the transcriptional activation domain of GAL4. Sug1 was recently proposed to be a subunit of the RNA polymerase II holoenzyme and to mediate the association of transcriptional activators with holoenzyme. We show here that Sug1 is not a subunit ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
