Key result
eIF1 is indispensable for forming the 48S initiation complex at the FMDV RNA AUG2 codon, while it reduces assembly at AUG1, indicating independent selection of the AUG2 initiation region.
The study elucidates the differential factor requirements and independent selection of the AUG2 initiation region in FMDV RNA translation.

eIF1's role in FMDV AUG selection is hypothesis-generating; extends initiation models but requires validation before any translational relevance.
Andreev et al. (2007) studied Foot-and-mouth disease virus (FMDV) RNA translation. eIF1 was evaluated on 48S translation initiation complex reconstitution at AUG1 and AUG2. eIF1 is indispensable for forming the 48S initiation complex at the FMDV RNA AUG2 codon, while it reduces assembly at AUG1, indicating independent selection of the AUG2 initiation region.
