UniProtKB description:  Forms a complex with host RAN and probably binds to exportins carrying activated MAPK in order to mediate the hyperphosphorylation of host Phe/Gly containing nuclear pore proteins (Nups) resulting in cessation of active nucleocytoplasmic transport (Probable). Proteins with NLS signals fail to import, cellular mRNAs fail to export, and some proteins small enough for diffusion are not retained anymore (efflux) (By similarity). The resulting inhibition of cellular protein synthesis serves to ensure maximal viral gene expression and to evade host immune response (By similarity). The leader protein also inhibits host interferon regulatory factor 3 (IRF3) dimerization, thereby blocking the transcriptional activation of IFN genes (By similarity). Binds to host RNase L thereby preventing its activation by 2'-5' oligoadenylates in order to counteract the antiviral interferon-inducible OAS/RNase L pathway (By similarity). Inhibits the integrated stress response (ISR) in the infected cell. Inhibits the host EIF2AK2/PKR by rendering this kinase unable to detect double-stranded RNA. Also impairs host stress granule formation probably by acting on a step downstream of EIF2AK2/PKR activation (PubMed:31292248).
