. Small ribosomal protein RPS0 stimulates translation initiation by mediating 40S-binding of eIF3 via its direct contact with the eIF3a/TIF32 subunit. PLoS ONE. 2012;7:e40464 pubmed publisher
..Together we conclude that the interaction between the flexible RPS0A-CTT and the residues 200-400 of the a/TIF32-NTD significantly stimulates attachment of eIF3 and its associated eIFs to small ribosomal subunits in vivo. ..

..Together, this suggests that eEF3 blocks Gcn1 regulatory function on the ribosome. We propose that the Gcn1-Gcn2 complex only functions on ribosomes with A-site-bound uncharged tRNA, because eEF3 does not occupy these stalled complexes. ..
