Abstract: Role of the coat protein E of the tick-borne encephalitis virus in the viral RNA replication in vitro was investigated. It is shown that addition of the exogenous E protein to the TBEV replicative complex inhibits the viral RNA synthesis, whereas addition of polyclonal and monoclonal antibodies against E protein effectively stimulates it. Affinity labelling technique and immunoblot staining of proteins revealed that E protein and anti-E antibodies affect the initiation stage of the viral RNA synthesis.
