Abstract
A new in vivo assay system has been developed to study programmed frameshifting in the yeast Saccharomyces cerevisiae. Frameshift signals are inserted between the Renilla and firefly luciferase reporter genes contained in a yeast expression vector and the two activities are directly measured from cell lysates in one tube. Similar to other bicistronic reporter systems, this one allows the efficient estimation of recoding efficiency by comparison of the normalized activity ratios from each luciferase protein. The assay system has been applied to HIV-1 and L-A directed programmed -1 frameshifting and Ty1 and Ty3 directed +1 frameshifting. The assay system is amenable to high-throughput screening.Entities:
