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)

RPN2

SEN3, proteasome regulatory particle base subunit RPN2, L000001864, YIL075C
Subunit of the 26S proteasome; substrate of the N-acetyltransferase Nat1p; protein abundance increases in response to DNA replication stress

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Evidence that mating by the Saccharomyces cerevisiae gpa1Val50 mutant occurs through the default mating pathway and a suggestion of a role for ubiquitin-mediated proteolysis.

Xu BE, Kurjan J

The yeast G alpha subunit, Gpa1p, plays a negative role in the pheromone response pathway. The gpa1Val50 mutant was previously shown to have a growth defect, consistent with the GTPase defect predicted for this mutation, and greatly reduced mating. Various explanations for the mating defect have been proposed. One approach to analyze the gpa1Val50 mating defect involved epistasis analysis. The ... [more]
