Notes: Adenomatous polyposis coli protein (APC) is shown to directly interact with HIV-1 Gag protein to stimulate Gag multimerization and spread of viral particles. Direct measurements of the Gag-Gag protein interaction were measured using the NanoBRET™ system. HeLa cells were co-transfected with Gag-HaloTag® and Gag-NanoLuc® expression vectors and BRET signal was monitored after 24 hours. ADC knockdown displayed a substantial decrease in viral production and Gag-Gag interaction. Together, the authors show ADC regulates Gag localization to the PM and viral packaging. (5058)
