Organism: Saffold virus (SafV) (Human TMEV-like virus-Saffold)
Function: 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).
