Binding of tick-borne encephalitis (TBE) virus RNA to proteins was studied by 3 methods: gel retardation, RNA-protein cross-linking under UV light, and RNA-protein blotting. Two cellular proteins with molecular weights about 30 and 22 kDa were detected in the nuclear fraction of two cell strains (PS and RH) and in blood mononuclear cells of patients with TBE. Weak interaction between the studied RNA and viral proteins can result from trace amounts of TBE virus proteins in infected cells and by lack of additional binding factors. Bacterial super-products and affinity chromatography for isolation of native glycoproteins were used to increase the amount of viral proteins. Purified E and NS1 proteins did not react with viral RNA, while incubation with recombinant nonstructural TBE virus NS3 protein led to a shift in the mobility of TBE virus RNA in gel in the absence of cross-linking under conditions of UV exposure after addition of heparin. Poor binding of nonstructural TBE virus NS3 protein is based on electrostatic binding. Oligoribonucleotide 14 nucleotide residues long corresponding to 5'-terminal of TBE virus genome did not react with NS3 protein, probably because of its small size or absence of certain sequences.
