Recombinant Outer Capsid Glycoprotein (VP7) of Rotavirus Expressed in Insect Cells Induces Neutralizing Antibodies in Rabbits

BACKGROUND Rotaviruses cause diarrhea in infants and young children worldwide. Rotavirus outer capsid protein, VP7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. Many efforts have been done to produce recombinant VP7 that maintain native characteristics. We used baculovirus expression system to produce rotavirus VP7 protein and to st...

Two proline residues are essential in the calcium-binding activity of rotavirus VP7 outer capsid protein.

Rotavirus maturation and stability of the outer capsid are calcium-dependent processes. It has been shown previously that the concentration of Ca2+-solubilizing outer capsid proteins from rotavirus particles is dependent on the virus strain. This property of viral particles has been associated with the gene coding for VP7 (gene 9). In this study the correlation between VP7 and resistance to low...

Genetic and antigenic variation of capsid protein VP7 of serotype G1 human rotavirus isolates.

The deduced amino acid sequences of the outer capsid protein, VP7, of serotype G1 rotavirus clinical isolates collected over a 6 year period (1990-1995) in Melbourne, Australia, were examined. Phylogenetic analysis characterized the sequences into two discrete clusters representing two of the four global lineages of human G1 VP7 proteins. Antigenic characterization using a panel of serotype G1-...
