Title
Direct detection of RNA transcription by FRET imaging using fluorescent protein probe
Abstract

We have constructed a reporter system for intracellular direct detection of RNA transcription that consists of two biomolecular components. The first part is a GFP-based recombinant protein probe (YRG0C-11ad) containing the RNA-binding Rev-peptide between ECFP and EYFP. The second component is RRE-RNA, which specifically binds to the Rev-peptide. Cells stably expressing YRG0C-11ad were identified by an increased FRET signal after direct transfection or intracellular transcription of RRE-RNA. In addition, the signal increase is more noticeable if tandemly repeated RRE-RNA is used as the reporter. Untranslatable non-coding RNAs are regarded as regulators of cellular gene expression, but they are difficult to study using indirect reporter systems that are dependent on translational products. Direct detection of reporter RNA would be a useful method for the detection of intracellular promoter activity during transcription of untranslatable RNAs.
