الوصف: | The carboxy-terminal domain (CTD) of eukaryotic initiation factor 5 (eIF5) plays a central role in the formation of the multifactor complex (MFC), an important intermediate for the 43 S preinitiation complex assembly. The IF5-CTD interacts directly with the translation initiation factors eIF1, eIF2-β, and eIF3c, thus forming together with eIF2 bound Met-tRNAi Met the MFC. In this work we present the high resolution crystal structure of eIF5-CTD. This domain of the protein is exclusively composed out of alpha-helices and is homologous to the carboxy-terminal domain of eIF2B-ε (eIF2Bε-CTD). The most striking difference in the two structures is an additional carboxy-terminal helix in eIF5. The binding sites of eIF2-β, eIF3 and eIF1 were mapped onto the structure. eIF2-β and eIF3 bind to non-overlapping patches of negative and positive electrostatic potential, respectively. © 2006 Elsevier Ltd.
