Multiple histone deacetylases are recruited by corepressor Sin3 and contribute to gene repression mediated by Opi1 regulator of phospholipid biosynthesis in the yeast Saccharomyces cerevisiae.

Abstract excerpt

Yeast genes of phospholipid biosynthesis are negatively regulated by repressor protein Opi1 when precursor molecules inositol and choline (IC) are available. Opi1-triggered gene repression is mediated by recruitment of the Sin3 corepressor complex. In this study, we systematically investigated the regulatory contribution of subunits of Sin3 complexes and identified Pho23 as important for IC-dependent gene...
