===Solution Structure of CSFV IRES Domain IIa===

~~==Overview==~~

<!--

~~Internal ribosome entry site (IRES) RNAs from~~ the ~~hepatitis C virus (HCV) and classical swine fever virus (CSFV) coordinate cap-independent assembly of eukaryotic 48S initiation complexes, consisting of~~ the ~~40S ribosomal subunit, eukaryotic initiation factor~~ (~~eIF) 3 and the eIF2~~/~~GTP~~/~~Met-tRNA(i)(Met~~) ~~ternary complex. Here~~, ~~we report that these IRESes also play a functional role during 80S ribosome assembly downstream of 48S complex formation, in promoting eIF5-induced GTP hydrolysis and eIF2/GDP release from~~ the ~~initiation complex~~. We show that this function is encoded in their independently folded IRES domain II and that it depends both on its characteristic bent conformation and two conserved RNA motifs, an apical hairpin loop and a loop E. Our data suggest a general mode of subunit joining in HCV and HCV-~~like IRESes.~~
