1 Identification of three genes required for the glucose-dependent transcription of the yeast transcriptional activator ADR1. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
2 Glucose repression of the ADH2 gene from Saccharomyces cerevisiae is mediated by the synthesis and activity of the transcriptional activator ADR1. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
3 In this study, we isolated mutations in three new genes (SAF1, SAF2 and SAF3) that suppressed the glucose-insensitive expression of ADH2 caused by the ADR1-5c allele. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
4 Each of the mutated SAF genes was found to suppress ADR1-5c activity by lowering ADR1-5c steady state mRNA levels 5- to 8-fold under glucose growth conditions. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
5 Each of the mutated SAF genes was found to suppress ADR1-5c activity by lowering ADR1-5c steady state mRNA levels 5- to 8-fold under glucose growth conditions. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
6 The stability of ADR1-5c mRNA was unaffected by mutations in each of the SAF genes, implying that the SAF genes are required for the transcription of ADR1 mRNA under glucose growth conditions. Glucose DNA-binding transcription factor ADR1 Saccharomyces cerevisiae S288C
