A Novel Fusion Protein for Inhibiting HIV Budding

Ubiquitin plays a critical role in HIV-1 budding. Vectors containing deubiquitin enzymes (DUbs) were constructed to deliver DUbs to HIV-1 production sites in living cells. The DUbs vectors comprise DUb cDNAs and cDNA expressing either HIV-1 gag, or the ESCRT protein TSG101.

Experimental data show that the fusion proteins expressed by the DUbs vectors retained their known protein-protein interactions and caused a significant and specific interruption of HIV-1 budding. The data suggest that the DUbs vectors could be used to inhibit HIV-1 infection or propagation in an individual. Thus, the DUbs vectors could potentially be used in high-risk individuals to prevent HIV-1 infection or as an adjunct therapy with known Anti-Retroviral Therapy (ART/HAART) in infected individuals.

Potential Commercial Applications: Competitive Advantages:
  • Prevention for HIV
  • Treatment for patients infected with HIV
  • Clinical research
  • Use for both treatment and prevention
  • No development of resistance to HIV

Development Stage:
In vitro data available
