Human immunodeficiency virus type 1 (HIV-1) Rev is a small RNA-binding protein which is essential for viral replication. To investigate the structure of Rev we have mapped the binding sites of a panel of monoclonal antibodies (mAb) by protein footprinting and identified a mAb protecting amino acids within both the N- and C-terminal parts of Rev. Our mapping results support a previously proposed structure (Auer et al., Biochemistry, 33 (1994) 2988-2996) predicting that a helix-loop-helix motif in Rev brings the termini of the protein into proximity. Furthermore, we demonstrate that the binding sites mapped by protein footprinting are in agreement with conventional epitope mapping results and that this technique provides an advantageous strategy for mapping discontinuous sites.
