| Long Description | Data Set loaded by Wayne. wt strain is YSW87 (MATa, ade2-101, his3Delta200, leu2Delta1, lys2-801, ura3D99, GAL2, GAL3, taf145::LEU2 [pSW104(AMP, CEN, TRP1, TAF145)]) Medline Abstract - Genome-wide expression analysis was used to identify genes whose expression depends on the functions of key components of the transcription initiation machinery in yeast. Components of the polymerase II holoenzyme, the general transcription factor TFIID, and the SAGA chromatin modification complex were found to have roles in expression of distinct sets of genes. The results reveal an unanticipated level of regulation which is superimposed on that due to gene-specific transcription factors, a novel mechanism for coordinate regulation of specific sets of genes when cells encounter limiting nutrients, and evidence that the ultimate targets of signal transduction pathways can be identified within the initiation apparatus. |
