The role of Grr1p in glucose sensing in Saccharomyces cerevisiae was elucidated through genome-wide transcription analysis. From triplicate analysis of a strain with deletion of the GRR1-gene from the genome and an isogenic reference strain, 68 genes were identified to have significantly altered expression using a Student's t-test with Bonferroni correction. These 68 genes were widely distributed across different parts of the cellular metabolism and GRR1-deletion is therefore concluded to result in polytrophic effects, indicating multiple roles for Grr1p. Using a less conservative statistical test, namely the SAM test, 232 genes were identified as having significantly altered expression, and also these genes were widely distributed across different parts of the cellular metabolism. Promoter analyses on a genome-wide scale and on the genes with significant changes revealed an over-representation of DNA-binding motifs for the transcriptional regulators Mig1p and Rgt1p in the promoter region of the significantly altered genes, indicating that Grr1p plays an important role in the regulatory pathways that ultimately lead to transcriptional regulation by each of the components Mig1p and Rgt1p.
