Quality Statement:
GSPT1/ERF3A mediates ETF1/ERF1 delivery to stop codons: The eRF1-eRF3-GTP complex binds to a stop codon in the ribosomal A-site.GTP hydrolysis by GSPT1/ERF3A induces a conformational change that leads to its dissociation, permitting ETF1/ERF1 to accommodate fully in the A-site. Binding of eRF1, eRF3, and GTP to pretermination complexes first induces a structural rearrangement that is manifested as a 2 nucleotide forward shift of the toeprint attributed to pretermination complexes that leads to GTP hydrolysis followed by rapid hydrolysis of peptidyl tRNA.
