Abstract

The influence of untranslated 5' sequences on c-myc expression was compared by measuring the translational efficiencies of mRNAs which contain leaders derived from exon 1 or intron 1 of the human c-myc gene. Expression plasmids were constructed and introduced into COS cells, and the levels of c-myc mRNA and protein were examined. Our results show that mRNAs transcribed from constructs containing exon 1 or intron 1, which have different folding potential, are translated with approximately equal efficiencies. This suggests that the translation of c-myc mRNA is not controlled by secondary structure alone. In addition, we observed that transcripts in which exon 1 was deleted are not translated more efficiently, but are present at a higher steady-state level. Thus, this example provides evidence for possible control at the transcriptional level. Finally, since the c-myc product was produced in each of our test systems, the results suggest that this protein does not regulate its own transcription or translation via a specific interaction with c-myc exon 1 alone.
