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
Saccharomyces cerevisiae (S288c)
PREY

RPN4

SON1, UFD5, stress-regulated transcription factor RPN4, L000001984, YDL020C
Transcription factor that stimulates expression of proteasome genes; Rpn4p levels are in turn regulated by the 26S proteasome in a negative feedback control mechanism; RPN4 is transcriptionally regulated by various stress responses; relative distribution to the nucleus increases 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]
