Figure 1.

(A) Schematic of the pGL3s-hRLuc construct. Upon translation of the dual luciferase mRNA two protein products were produced, a 36 kDa termination product (RLuc only) and a 102 kDa readthrough product (RLuc:Luc+ fusion). (B) Heat map of mean measured readthrough efficiency for 192 constructs (all possible permutations of the +4 to +6 positions for each stop codon). Top left quadrant, UAA; top right quadrant, UAG; bottom left quadrant, UGA. ‘+2’ and ‘+3’ refer to the identity of the second and third bases in the stop codon; ‘+4’, ‘+5’ and ‘+6’ refer to the three nucleotides immediately 3′ to the stop codon. Data are available in Supplementary Table S1.
