Results from mechanistic studies indicated that rilpivirine , etravirine , and efavirenz , but not nevirapine or delavirdine , bound to the ligand - binding domain of hPXR , as assessed by a transactivation assay and by a competitive ligand - binding assay using time - resolved fluorescence resonance energy transfer ; triggered nuclear translocation of a green fluorescence protein - tagged hPXR , as visualized by confocal imaging ; and recruited steroid receptor coactivator - 1 ( SRC - 1 ) , SRC - 2 , and SRC - 3 to hPXR , as demonstrated by mammalian two - hybrid assays .
