[Heterogeneity of virus-specific flavivirus proteins]

The polyacrylamide gel analysis of large intracellular virus-specific proteins NV5, NV4, and the intracellular form of structural protein V3 established differences in the electrophoretic mobility of each of these proteins formed in cells infected with tick-borne encephalitis, Powassan, Langat, and West Nile viruses. It is assumed that these differences in the electrophoretic mobility of NV5, NV4 proteins, and the intracellular form of V3 protein reflect the differences in the primary structure of each of these proteins in the viruses examined.
