Abstract
Sequences for two reovirus ribosome-protected fragments are presented. Comparison with four other reovirus initiation sites reveals only two common features: the 5′-terminal sequence m7GpppGmCUA, and (located 15–33 nucleotides from the cap) the sequence AUGG. Both the cap and the AUG codon are included in the 40S-ribosome protected region from all six reovirus messages.
