| + | The X-ray structure of the phylogenetically conserved middle portion of human eukaryotic initiation factor (eIF) 4GII has been determined at 2.4 A resolution, revealing a crescent-shaped domain consisting of ten alpha helices arranged as five HEAT repeats. Together with the ATP-dependent RNA helicase eIF4A, this HEAT domain suffices for 48S ribosomal complex formation with a picornaviral RNA internal ribosome entry site (IRES). Structure-based site-directed mutagenesis was used to identify two adjacent features on the surface of this essential component of the translation initiation machinery that, respectively, bind eIF4A and a picornaviral IRES. The structural and biochemical results provide mechanistic insights into both cap-dependent and cap-independent translation initiation. | ||
