[Complex formation between recombinant protein VPg of potato virus Y and heterologous eukaryotic translation initiation factors eIF4E].

Genomes of some positive-strand RNA viruses do not contain cap-structure, but instead their 5'-end is covalently linked to a viral protein called VPg. Complex formation between VPg and cellular translation initiation factors (eIFs) has been extensively studied in the context of the model of this complex involvement in virus mRNA translation initiation and cellular protein translation shut down in infected cells. The potato virus (PVY) VPg was expressed in bacterial and baculovirus systems in order to investigate its binding capacity to wheat eIF4E and its isoform.

[Heterologous protein expression in the baculovirus vector system: the nuclear polyhedrosis virus of Malacosoma neustria in Antheraea pernyi cells].

The results of the creation of new expressive system on Malacosoma neustria nuclear polyhedrosis virus and cell line originated from Antheraea pernyi tissues was demonstrated. The expression of bacterial beta-galactosidase-coding gene was analyzed in this system.
