Interactions Of The Cellular Sumoylation System With Influenza A Virus And Its Non-Structural Protein Ns1a (Ns1a), Sangita Pal

Open Access Theses & Dissertations

The most important current anti-influenza weapons, vaccination and antiviral drugs, can be rapidly rendered fully ineffective thanks to the virus's high mutational rate, which produces viruses exhibiting new antigenic properties and structural proteins insensitive to the drug's mechanism of action. One attractive alternative is to develop drugs that modulate the activity of cellular systems either required for viral growth or able to neutralize viral growth. Here we demonstrate that the cellular SUMOylation system, a post-translational modification involving the conjugation of the Small Ubiquitin-like MOdifier (SUMO) to specific protein targets using a Ubiquitin-like enzymatic cascade, interacts closely with influenza virus during …
