In vivo expression of the CAT reporter gene under control of mutations in the leader. (A) Effect of uORF mutations in the context of linear and structured shunt-competent mRNA leaders. Note that translation efficiencies represented by bars are plotted in a logarithmic scale. (B) Effect of the CaMV-specific translational transactivator of reinitiation on translation. See Fig. 4 for constructs.
