The Xenopus RNA polymerase I transcription factor, UBF, has a role in transcriptional enhancement distinct from that at the promoter.
Repeated sequence elements found upstream of the ribosomal gene promoter in Xenopus function as RNA polymerase I-specific transcriptional enhancers. Here we describe an in vitro system in which these enhancers function in many respects as in vivo. The principal requirement for enhancer function in v...
