NRG1

transcriptional regulator NRG1, L000004598, YDR043C
Transcriptional repressor; recruits the Cyc8p-Tup1p complex to promoters; mediates glucose repression and negatively regulates a variety of processes including filamentous growth and alkaline pH response; activated in stochastic pulses of nuclear localization in response to low glucose

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Publication

The pH-sensing Rim101 pathway positively regulates the transcriptional expression of the calcium pump gene PMR1 to affect calcium sensitivity in budding yeast.

Yan H, Fang T, Xu H, Jiang L

In Saccharomyces cerevisiae, the Rim101 pathway senses extracellular pH changes through a complex consisted of Rim8, Rim9 and Rim21 at the plasma membrane. Activation of this sensor complex induces a proteolytical complex composed of Rim13 and Rim20 and leads to the C-terminal processing and activation of the transcription factor Rim101. Deletion mutants for RIM8, RIM9, RIM13, RIM20, RIM21 and RIM101 ... [more]

Negative Genetic

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.
