What's a GeneRIF?

The yeast transcription factor Stb5 acts as a negative regulator of autophagy by modulating cellular metabolism.
Title: The yeast transcription factor Stb5 acts as a negative regulator of autophagy by modulating cellular metabolism.
Comparison between instrumental variable and mediation-based methods for reconstructing causal gene networks in yeast.
Title: Comparison between instrumental variable and mediation-based methods for reconstructing causal gene networks in yeast.
Transcriptome analysis of an STB5 deletion strain revealed transcriptional changes in direct regulation targets of Stb5, including several pentose phosphate pathway genes as well as additional novel regulatory targets, but interestingly not including the proposed pentose phosphate pathway flux controlling enzyme Zwf1.
Title: Integrated analysis of the yeast NADPH-regulator Stb5 reveals distinct differences in NADPH requirements and regulation in different states of yeast metabolism.
These findings suggest a major role for the transcription factor Stb5p in maintaining a basal flux through the pentose phosphate pathway to meet the NADPH requirements for aerobic growth, and to provide the nucleotide precursors.
Title: The Saccharomyces cerevisiae zinc factor protein Stb5p is required as a basal regulator of the pentose phosphate pathway.
Stb5p functions as a transcriptionalr egulator controlling expression of the PPP genes and glucose-6-phosphate isomerase, which leads to acetaldehyde tolerance.
Title: Transcription factor Stb5p is essential for acetaldehyde tolerance in Saccharomyces cerevisiae.
YMR315W transcription is regulated by Stb5p in response to diamide induced NADPH depletion.
Title: The Saccharomyces cerevisiae YMR315W gene encodes an NADP(H)-specific oxidoreductase regulated by the transcription factor Stb5p in response to NADPH limitation.
These data suggest that Stb5 is a key player in the control of NADPH production for resistance to oxidative stress.
Title: Oxidative stress-activated zinc cluster protein Stb5 has dual activator/repressor functions required for pentose phosphate pathway regulation and NADPH production.

Preferred Names: Stb5p

NP_012048.3

Transcription factor; regulates multidrug resistance and the oxidative stress response; forms a heterodimer with Pdr1p; contains a Zn(II)2Cys6 zinc finger domain that interacts with a pleiotropic drug resistance element in vitro; negative regulator of autophagy, modulating the transcription of genes involved in NADPH production and the pentose phosphate pathway; Stb5p expression is reduced during nitrogen starvation and autophagy induction, while STB5 mRNA levels are significantly increased
