(A) Metagene analysis of translation termination. Average ribosome occupancy from all genes aligned at their stop codons for WT and eIF5Ad cells. Arrow denotes stacked ribosomes ~30 nt upstream the stop codon peak.
(B) Overlay and close-up view of (A), showing accumulated ribosomes in 3′ UTRs in eIF5Ad cells.
(C) Similar to (A), metagene plot of stop codons for WT and eIF5Ad lysates treated with high-salt buffer.
(D) Similar to (B), close-up view of 3′ UTR regions for WT and eIF5Ad lysates after high-salt wash. See also Figure S5.
