Abstract excerpt
An AUG-initiated upstream open reading frame (uORF) encoding a potential polypeptide of 3 to 13 amino acids (aa) is found within the 5' untranslated region (UTR) of >75% of coronavirus genomes based on 38 reference strains. Potential CUG-initiated uORFs are also found in many strains. The AUG-initiated uORF is presumably translated following genomic 5'-end cap-dependent ribosomal scanning, but its function is...
