Abstract
The Neurospora crassa arg-2 upstream open reading frame (uORF) plays a role in negative arginine-specific translational regulation. Primer extension inhibition analyses of arg-2 uORF-containing RNA translated in a cell-free system in which arginine-specific regulation was retained revealed "toeprints" corresponding to ribosomes positioned at the uORF initiation and termination codons and at the downstream initiation codon. At high arginine concentrations, the toeprint signal corresponding to ribosomes at the uORF termination codon rapidly increased; a new, broad toeprint that represents additional ribosomes stalled on the uORF appeared 21 to 30 nucleotides upstream of this site; and the toeprint signal corresponding to ribosomes at the downstream initiation codon decreased. These data suggest that arginine increases ribosomal stalling and thereby decreases translation from the downstream initiation codon.
