Multiple intragenic elements regulate the expression of the murine N-ras gene.
We have identified two separate regions within the murine N-ras transcription unit which may participate in the regulation of N-ras gene expression. One of these regions, localized to the first half of intron 1, contains a site of premature transcriptional arrest. We propose that premature transcription termination, which has been identified as an important control mechanism for several genes, may also play a role in the regulation of the N-ras gene. In addition, we have identified a positively acting region within the N-ras transcription unit. This region, localized to the end of intron 1/beginning of exon 1, was found to greatly increase expression from the N-ras promoter.
