Project description:We report gene expression data for strains that overexpress the transcriptional repressors Yox1 or Yhp1 from a synthetic, estradiol-inducible promoter. Gene expression was also measured in strains that overexpress unphosphorylatable alleles of either Yox1 or Yhp1, to determine whether blocking phosphorylation of these proteins by Cdk1 changes the spectrum of regulated genes. Finally, gene expression was measured in corresponding control strains in which Yox1/Yhp1 proteins were expressed from their endogenous promoters. These data demontsrate that Yox1 is a stronger repressor than Yhp1, although they regulate the same genes. In addition, phosphodeficient alleles of each TF regulate the same genes as the wild type proteins.
Project description:We report gene expression data for yeast strains expressing mutated versions of the transcriptional repressors Yox1 and Yhp1 that can't be phosphorylated by Cdk1. For comparision, gene expression was also measured in cells with deletions in one or both repressors. Genes that are downregulatd in phosphomutant strains and upregulated in deletion strains are likely to be target genes of these transcriptional repressors.
