Translation initiation sites that precede the main coding sequence (CDS) of a transcript give rise to upstream open reading frames (uORFs). The presence of uORFs affects initiation rates at the CDS by interfering with unrestrained progression of ribosomes across the 5ยด-transcript leader sequence.

 

Accumulating evidence suggests that uORF-mediated translational control is of outstanding importance for the regulation of protein expression in health and disease.
