Abstract:
We have determined that a 69-base-pair (bp) monkey DNA sequence, previously found to enhance simian virus 40 replication, has transcriptional enhancer activity as well. Consensus recognition sites for the transcription factor AP-1, present at each end of this sequence, are partially responsible for its replication- and transcription-enhancing activities. Other motifs within the 69-bp monkey sequence also act to increase the levels of replication and transcription. The activity of the monkey sequence is augmented by the presence of a simian virus 40 21-bp repeat. The 69-bp sequence enhances transcription but not replication from a distance. We conclude that the stimulation of replication and transcription can be uncoupled, suggesting that different mechanisms may be involved.
