eIF1A structure and position on the ribosome. a eIF1A structure shown in ribbon. The OB-fold domain and the N- and C-termini are labeled. b Position of eIF1A, in surface representation, on the ribosome [36]. The 18S rRNA is shown in beige; eIF1 (magenta) and small ribosomal subunit protein 23 (rpS23, red) are shown and labeled in the zoomed-in box on the bottom-left. The rest of the small ribosomal subunit proteins are not shown. The Tetrahymena thermophila 40S ribosomal subunit and eIF1 are from 4bts.pdb; human eIF1A is from 1d7q.pdb
