Transcription profiling of S. cerevisiae haploid Sigma1278b strains expressing different combinations and variants of TEC1 and STE12

ABSTRACT: We determined and classified Tec1-regulated genes in haploid strains of the Sigma1278b genetic background under vegetative growth conditions. For this purpose, we measured transcriptional profiles of five different haploid MATa yeast strains of the following relevant genotypes: (53 = YHUM1694) TEC1 STE12; (64 = YHUM1700) tec1? STE12; (66 = YHUM1701) tec1? ste12?; (10 = YHUM1676) (P)URA3-TEC1 ste12?; (42 = YHUM1642) (P)URA3-TEC1 1-280-STE12 1-688 tec1? ste12?. All strains were grown in duplicate in SC medium lacking leucine and histidine at 30 degree C to an optical density of 1.0 before extraction of total RNA and transcriptional profiling.

In Saccharomyces cerevisiae, the TEA transcription factor Tec1 is known to regulate target genes together with a second transcription factor, Ste12. Tec1-Ste12 complexes can activate transcription through Tec1 binding sites (TCSs), which can be further combined with Ste12 binding sites (PREs) for cooperative DNA binding. However, previous studies have hinted that Tec1 might regulate transcription also without Ste12. Here, we show that in vivo, physiological amounts of Tec1 are sufficient to stim  ...[more]
