Abstract The general transcription factor IIA (TFIIA) forms a complex with TFIID at the TATA promoter element, and it inhibits the function of several negative regulators of the TATA-binding protein (TBP) subunit of TFIID. Biochemical experiments suggest that TFIIA is important in the response to transcriptional activators because activation domains can interact with TFIIA, increase recruitment of TFIID and TFIIA to the promoter, and promote isomerization of the TFIID-TFIIA-TATA complex. Here, we describe a double-shut-off approach to deplete yeast cells of Toa1, the large subunit of TFIIA, to <1% of the wild-type level. Interestingly, such TFIIA-depleted cells are essentially unaffected for activation by heat shock factor, Ace1, and Gal4-VP16. However, depletion of TFIIA causes a general two- to threefold decrease of transcription from most yeast promoters and a specific cell-cycle arrest at the G2-M boundary. These results indicate that transcriptional activation in vivo can occur in the absence of TFIIA.

RAP30/74 is a human general transcription factor that binds to RNA polymerase II and is required for initiation of transcription in vitro regardless of whether the promoter has a recognizable TATA box (Z. F. Burton, M. Killeen, M. Sopta, L. G. Ortolan, and J. F. Greenblatt, Mol. Cell. Biol. 8:1602-1613, 1988). Part of the amino acid sequence of RAP30, the small subunit of RAP30/74, has limited homology with part of Escherichia coli sigma 70 (M. Sopta, Z. F. Burton, and J. Greenblatt, Nature (London) 341:410-414, 1989). To determine which sigmalike activities of RAP30/74 could be attributed to RAP30, we purified human RAP30 and a RAP30-glutathione-S-transferase fusion protein that had been produced in E. coli. Bacterially produced RAP30 bound to RNA polymerase II in the absence of RAP74. Both partially purified natural RAP30/74 and recombinant RAP30 prevented RNA polymerase II from binding nonspecifically to DNA. In addition, nonspecific transcription by RNA polymerase II was greatly inhibited by RAP30-glutathione-S-transferase. DNA-bound RNA polymerase II could be removed from DNA by partially purified RAP30/74 but not by bacterially expressed RAP30. Thus, the ability of RAP30/74 to recruit RNA polymerase II to a promoter-bound preinitiation complex may be an indirect consequence of its ability to suppress nonspecific binding of RNA polymerase II to DNA.
