The gene-external part of the human 7S L promoter was analyzed by transcription in vitro and in vivo. Compared to the wild type promoter (-178), a -66 5'deletion mutant revealed full activity in vitro but was inefficiently transcribed in vivo. Further deletion to -37 reduced template activity to 50% in vitro and to basal level expression in vivo (below 5%).(More)
Fractions obtained from HeLa cell extracts were used to study RNA polymerase III-catalyzed transcription from the human 7SK and mouse U6 RNA promoters in vitro. Although both genes depend on two almost identical core promoter elements (TATA box and PSE), different fractions were required. The 7SK promoter revealed full activity with the phosphocellulose B(More)
