Transcription from the cyclin A and D1 but not the c-<jats:italic>fos<\/jats:italic> and <jats:italic>myc<\/jats:italic> promoters is also dramatically reduced in ts13 cells at the nonpermissive temperature. These findings provide an intriguing link between TAF-mediated transcriptional regulation and cell cycle progression. Here we report the mapping of an enhancer element in the cyclin A promoter (TSRE) that responds to mutations in TAF<jats:sub>II<\/jats:sub>250. An analysis of chimeric promoter constructs reveals that the cyclin A TSRE can confer TAF<jats:sub>II<\/jats:sub>250 dependence to the core promoter of c-<jats:italic>fos.<\/jats:italic> In addition, reciprocal hybrid promoter constructs suggest that TAF<jats:sub>II<\/jats:sub>250 also contributes to the transcriptional properties of the cyclin A core promoter. We have purified and identified cellular activators that specifically bind to the TSRE and mediate transcription in a TAF<jats:sub>II<\/jats:sub>250-dependent manner. By micropeptide sequencing, we determined that TSRE-binding proteins include members of the activating transcription factor (ATF) family. These results suggest that the <jats:italic>ts13<\/jats:italic> mutation of TAF<jats:sub>II<\/jats:sub>250 has compromised the ability of TFIID to mediate activation of transcription by specific enhancer factors such as ATF, as well as to perform certain core promoter functions. These defects in TAF<jats:sub>II<\/jats:sub>250 apparently result in the down-regulation of key molecules, such as cyclin A, which may be responsible for the ts13 cell cycle arrest phenotype.<\/jats:p>","DOI":"10.1101\/gad.11.20.2658","type":"journal-article","created":{"date-parts":[[2008,2,20]],"date-time":"2008-02-20T22:15:26Z","timestamp":1203545726000},"page":"2658-2669","source":"Crossref","is-referenced-by-count":73,"title":["TAF<sub>II<\/sub>250-dependent transcription of cyclin A is directed by ATF activator\u2009proteins"],"prefix":"10.1101","volume":"11","author":[{"given":"Edith H.","family":"Wang","sequence":"first","affiliation":[]},{"given":"Sharleen","family":"Zou","sequence":"additional","affiliation":[]},{"given":"Robert","family":"Tjian","sequence":"additional","affiliation":[]}],"member":"246","published-online":{"date-parts":[[1997,10,15]]},"reference":[{"key":"2021111418475547000_11.20.2658.1","doi-asserted-by":"publisher","DOI":"10.1101\/gad.10.18.2368"},{"key":"2021111418475547000_11.20.2658.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0959-437X(05)80335-1"},{"key":"2021111418475547000_11.20.2658.3","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(89)90578-3"},{"key":"2021111418475547000_11.20.2658.4","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(94)90403-0"},{"key":"2021111418475547000_11.20.2658.5","doi-asserted-by":"crossref","first-page":"3301","DOI":"10.1128\/MCB.15.6.3301","article-title":"Cell cycle regulation of cyclin A gene expression by the cyclic AMP-responsive transcription factors CREB and CREM.","volume":"15","author":"Desdouets","year":"1995","journal-title":"Mol.
