The invention relates to a translational recoding reporter construct comprising: a first fluorescent protein coding sequence; a second fluorescent protein coding sequence encoding a fluorescent protein different from the first fluorescent protein; and a linker sequence interposed between the first and second fluorescent protein coding sequence; wherein the a first fluorescent protein coding sequence and the second fluorescent protein coding sequence are out-of-frame with respect to each other but are co-expressed as a single fusion polypetpdie upon recoding. The invention also relates to methods of use of the construct in screening modulators of recoding.
