What's a GeneRIF?

Cytosolically made inositol and CDP-diacylglycerol can access the active site of the yeast PI synthase Pis1 from the cytosolic side and that Pis1 structure is strongly affected by mild detergents.
Title: The active site of yeast phosphatidylinositol synthase Pis1 is facing the cytosol.
Ume6p was found to be a positive regulator of PIS1 gene expression.
Title: Transcription regulation of the Saccharomyces cerevisiae PIS1 gene by inositol and the pleiotropic regulator, Ume6p.
multiple upstream AUG codons are present in at least some PIS1 transcripts and negatively impact PIS1 expression
Title: Expression of the Saccharomyces cerevisiae PIS1 gene is modulated by multiple ATGs in the promoter.
This study employed a genomic screen, database mining, and more traditional promoter analysis to identify genes that affect PIS1 expression.
Title: Genomic analysis of PIS1 gene expression.
PIS1-encoded phosphatidylinositol synthase in Saccharomyces cerevisiae is regulated by zinc
Title: Regulation of the PIS1-encoded phosphatidylinositol synthase in Saccharomyces cerevisiae by zinc.
Enhanced phosphatidylinositol synthesis may account for PIS1 suppression of rsp5 defects.
Title: Enhanced levels of Pis1p (phosphatidylinositol synthase) improve the growth of Saccharomyces cerevisiae cells deficient in Rsp5 ubiquitin ligase.
