Position of eukaryotic initiation factor eIF1 on the 40S ribosomal subunit determined by directed hydroxyl radical probing

Eukaryotic initiation factor (eIF) eIF1 maintains the fidelity of initiation codon selection by enabling 43S complexes to reject codon–anticodon mismatches, to recognize the initiation codon context, and to discriminate against establishing a codon–anticodon interaction with AUGs located
