A single amino acid substitution in the V protein of Nipah virus alters its ability to block interferon signalling in cells from different species

Abstract

The V protein of the paramyxovirus Nipah virus (NiV) has been shown to antagonize the interferon (IFN) response in human cells via sequestration of STAT1 and STAT2. This study describes a mutant of the NiV V protein, referred to as V(AAHL), that is unable to antagonize IFN signalling and demonstrates that a single amino acid substitution is responsible for… (More)
