Cover Story: The analysis of avian calicivirus genomes has revealed unexpected complexity in their coding and noncoding regions. Their 5’-untranslated regions are exceptionally long, and many of them contain picornavirus-like IRESs, mostly type 2, which were likely acquired by horizontal gene transfer. We confirmed the activity of representative IRESs and elucidated their mechanism of action by in vitro reconstitution using the purified components of the translation apparatus. The principal open reading frame (ORF1) in these genomes commonly overlaps a second 200–300 codon-long ORF (designated ORF1*). ORF1* translation is also mediated by IRESs and involves leaky scanning. These IRESs and ORF1* polypeptides have conserved sequences, suggestive of conserved functions, and they could potentially influence the pathogenicity of avian caliciviruses. View this paper
