Human immunodeficiency virus type 1 (HIV-1) encodes a trans-acting regulatory protein, termed Rev, which is critically required for virus replication. Rev is a sequence-specific RNA binding protein which mediates the nuclear export of unspliced and incompletely spliced viral mRNAs encoding the viral structural proteins. While CD and fluorescence measurements have provided several possible structural models of Rev, all attempts employing X-ray crystallography and NMR techniques have so far failed to provide more accurate data. We present a new approach to validate alternative structural models of the N-terminal region of Rev which contains the nuclear localization/RNA binding domain. Points of contact between structural elements in a protein were determined by introduction of targeted amino acid substitutions and subsequent scoring of the biological activities. Our data resulted in the suggestion of a new and more refined model of HIV-1 Rev structure which to date has been impossible to obtain by other means.
