Retroviruses must overcome cellular restrictions to the nucleocytoplasmic export of viral mRNAs that retain introns in order to complete their replication cycle. HIV accomplishes this using a system comprised of a trans-acting viral protein, Rev, and a cis-acting RNA secondary structure in the viral genome, the Rev-Response Element (RRE). HIV primary isolates differ with respect to the sequence and functional activity of the Rev-RRE system. Here, we describe a high throughput assay system for analyzing Rev-RRE functional activity using packageable viral vectors.
