Prediction of human rotavirus serotype by nucleotide sequence analysis of the VP7 protein gene

Sequence of the gene encoding the major neutralization antigen (VP7) of serotype 10 rotavirus.

The sequence of the gene encoding the major neutralization antigen (VP7) of the type member (bovine virus strain B223) of the proposed serotype 10 of rotavirus has been determined. This was done using a rapid new strategy involving direct sequencing by primer extension of cDNA generated from the relevant virus gene (gene 8) using a combined reverse transcription/polymerase chain reaction. The s...

Cloning of Rotavirus Outer Capsid Protein (VP7) Gene into the pGEM Vector

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-...

Identification of two subtypes of serotype 4 human rotavirus by using VP7-specific neutralizing monoclonal antibodies.

Two distinct subtypes of human rotavirus serotype 4 were identified by using neutralizing monoclonal antibodies directed to the major outer capsid glycoprotein, VP7, of strains ST3 (subtype 4A) and VA70 (subtype 4B). Specimens containing serotype 4 rotavirus, obtained from different countries, were examined for subtyping by using solid-phase immune electron microscopy, enzyme-linked immunosorbe...

Nucleotide sequence of the gene encoding the serotype-specific glycoprotein of UK bovine rotavirus.

The nucleotide sequence of the gene which encodes the major outer-shell glycoprotein of UK bovine rotavirus has been determined. The dsRNA genome segment encoding this protein was converted into ds cDNA and cloned into pBR322 for sequence studies. The gene is 1062 base pairs in length and contains a single, long, open reading-frame capable of coding for a protein of 326 amino-acids. This would ...
