Marburg virus VP35 can both fully coat the backbone and cap the ends of dsRNA for interferon antagonism.
Filoviruses, including Marburg virus (MARV) and Ebola virus (EBOV), cause fatal hemorrhagic fever in humans and non-human primates.All filoviruses encode a unique multi-functional protein termed VP35.The C-terminal double-stranded (ds)RNA-binding domain (RBD) of VP35 has been implicated in interferon antagonism and immune evasion.Crystal structures
