The Zaire Ebola virus (EBOV) protein VP35 is multifunctional; it inhibits IFN-α/β production and functions as a cofactor of the viral RNA polymerase. Mass spectrometry identified the double stranded RNA binding protein 76 (DRBP76/NFAR-1/NF90) as a cellular factor that associates with the VP35 C-terminal interferon inhibitory domain (IID). DRBP76 is described to regulate host cell protein synthesis and play an important role in host defense. The VP35-IID-DRBP76 interaction required the addition of exogenous dsRNA, but full-length VP35 associated with DRBP76 in the absence of exogenous dsRNA. Cells infected with a Newcastle disease virus (NDV)–expressing VP35 redistributed DRBP76 from the nucleus to the cytoplasm, the compartment in which EBOV replicates. Overexpression of DRBP76 did not alter the ability of VP35 to inhibit type I IFN production but did impair the function of the EBOV transcription/replication complex. These data suggest that DRBP76, via its association with VP35, exerts an anti-EBOV function.
