General annotation (Comments)

Function

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. This blockage is produced through the interaction with and inhibition host IKBKE and TBK1 producing a strong inhibition of the phosphorylation and activation of IRF3. Also inhibits the antiviral effect mediated by the interferon-induced, double-stranded RNA-activated protein kinase EIF2AK2/PKR By similarity.

Subunit structure

Homooligomer. Homomultimerizes via the coiled coil domain. Found in a trimeric complex in which VP35 bridges L and the nucleoprotein By similarity. May interact with VP40. Interacts with host IKBKE and TBK1; the interactions lead to inhibition of cellular antiviral response by blocking necessary interactions of IKBKE and TBK1 with their substrate IRF3 By similarity.

Subcellular location

Virion. Host cytoplasm By similarity.

Post-translational modification

Phosphorylated by host IKBKE By similarity.

Sequence similarities

Belongs to the filoviridae polymerase cofactor VP35 family.
