WebApr 1, 2024 · Our luciferase-based biosensor assay complements a recently described FlipGFP-based biosensor assay (Froggatt et al., 2024). Similar to the luciferase reporter, the FlipGFP reporter fluoresces only after cleavage by 3CLpro. The FlipGFP reporter was shown to be cleaved by 3CLpro of multiple alpha- and beta-CoVs and can be used in … WebSignificantly, we developed a cell-based FlipGFP assay that can be applied to predict the cellular antiviral activity of PLpro inhibitors in the BSL-2 setting. X-ray crystal structure of PLpro in complex with GRL0617 showed that binding of GRL0617 to SARS-CoV-2 induced a conformational change in the BL2 loop to a more closed conformation.
