Abstract

Eukaryotic translation initiation requires cooperative assembly of a large protein complex at the 40S ribosomal subunit. We have resolved a budding yeast initiation complex by cryo-EM, allowing placement of prior structures of eIF1, eIF1A, eIF3a, eIF3b and eIF3c. Our structure highlights differences in initiation-complex binding to the ribosome compared to that of mammalian eIF3, demonstrates a direct contact between eIF3j and eIF1A and reveals the network of interactions between eIF3 subunits.
