GTPBP1 and viral infectious disease: Here, to facilitate the investigation of the critical events in viral infection and to identify the antiviral activity of neutralizing and ADCC-inducing antibodies, we generated a replication incompetent GP1,2-pseudotyped virus expressing the Fluc reporter protein (pHIV–ZGP–Fluc) using an envelope-defective strain of HIV-1 (strain SG3) as a way of safely and sensitively monitoring viral infections in cells and mice.
