Crystal structure of Reston Ebola virus VP35 RNA binding domain bound to 12-bp dsRNACrystal structure of Reston Ebola virus VP35 RNA binding domain bound to 12-bp dsRNA
Template:ABSTRACT PUBMED 23824825
FunctionFunction
[VP35_EBORR] Acts as a polymerase cofactor in the RNA polymerase transcription and replication complex. Prevents establishment of cellular antiviral state by blocking virus-induced phosphorylation and activation of interferon regulatory factor 3 (IRF3), a transcription factor critical for the induction of interferons alpha and beta. The mechanism by which this blockage occurs remains incompletely defined, a hypothesis suggests that VP35 dsRNA-binding activity prevents activation of IRF3 by sequestering dsRNA. Also inhibits the antiviral effect mediated by the interferon-induced, double-stranded RNA-activated protein kinase EIF2AK2/PKR (By similarity).
