Abstract excerpt
Repressor protein Opi1 is required to negatively regulate yeast structural genes of phospholipid biosynthesis in the presence of precursor molecules inositol and choline (IC). Opi1 interacts with the paired amphipathic helix 1 (PAH1) of pleiotropic corepressor Sin3, leading to recruitment of histone deacetylases (HDACs). Mutational analysis of the Opi1-Sin3 interaction domain (OSID) revealed that hydrophobic OSID...
