Gene profiling of TRA1 and tra1-L3733A

ABSTRACT: Tra1 is a component of the Saccharomyces cerevisiae SAGA and NuA4 complexes and a member of the phosphatidylinositol 3-kinase kinase family that contain a C-terminal PI3K domain followed by a 35-residue FATC domain. We analyzed alleles with single residue changes in the FATC domain. Of these tra1-L3733A had the most pronounced effects, resulting in phenotypes similar but not identical to those resulting from mutations in the PI3K domain or SAGA or NuA4 components. To analyze the transcriptional effects of the tra1-L3733A allele, we performed gene profiling of wild-type and tra1-L3733A strains. Expression of 11 genes was elevated ≥ 2-fold, 79 genes were decreased ≥ 2-fold. Of the 11 genes with elevated expression, four (HSP26, PIR3, DDR2 and GRE1) have roles in cellular stress response.
