We isolated and characterized the 5′ region of the mouse c-Ki-rasgene, including a 5′ untranslated exon (exon 0). These studies used genetic material from Y1 mouse adrenocortical tumor cells in which the c-Ki-rasgene is amplified and overexpressed. Our data demonstrate that transcription initiates at multiple sites, predicting size heterogeneity at the 5′ ends of the c-Ki-rasmRNAs. Using transient expression assays, we identified a genomic fragment within the 5′ region which exhibits bidirectional promoter activity.
