RNA polymerase II (RNAPII) requires a set of general transcription factors )TFIIA, TFIIB, TFIID, TFIIE, TFIIF and TFIIH)to initiate transcription from a gene promoterin vitro. General transcription factors have been isolated from Saccharomyces cerevisiae,rat, human and Drosophila,and their corresponding cDNAs have been cloned. In this report, we describe a reconstitutedin vitro transcription system that consists of the following prepara-tions of factors from the yeastSchizosaccharomyces pombe: affinity-purified RNAPII, TFIIH, and recombinant TBP, TFIIB, TFIIE and TFIIF. ...
