Abstract |
The discovery of novel antivirals for HIV and HCV has been a focus of intensive research for many years. Where the inhibition of critical viral enzymes by small molecules has proven effective for many viruses, there is considerable merit in pursuing protein-protein interactions (PPIs) as targets for therapeutic intervention. The mammalian protein-protein interaction trap (MAPPIT) is a two-hybrid system used for the study of PPIs. The bait and prey proteins are linked to deficient cytokine receptor chimeras, where the bait and prey interaction and subsequent ligand stimulation restores JAK-STAT signaling, resulting in reporter gene expression controlled by a STAT3-responsive promoter. We report the use of MAPPIT as a high-throughput screening assay for the discovery of inhibitors or stimulators of the Vif-APOBEC3G interaction and the reverse transcriptase heterodimerization (RTp66-RTp51) for HIV and the NS4A-NS3 interaction for HCV. |
