pubmed:abstractText |
Adult diarrheal rotavirus (ADRV) is a currently noncultivatable group B human rotavirus responsible for epidemic outbreaks of gastroenteritis in China. Gene segment 5 of ADRV encodes the major inner capsid protein, VP6. ADRV gene 5 was inserted into a recombinant baculovirus by homologous recombination between baculovirus shuttle plasmid pACYM1-AD5 and AcNPV genomic DNA. Baculovirus recombinants were selected visually and plaque purified and VP6 expression was detected by Coomassie staining of PAGE-separated proteins. The baculovirus-expressed gene 5 polypeptide is 44 kDa, the same as for the major inner capsid protein present on EDTA-treated ADRV virions and in vitro-expressed VP6 protein. The expressed protein is oligomeric and in the absence of reducing agents multimerizes to apparent trimer, hexamer, and greater molecular mass as assayed by SDS-PAGE. The VP6 protein is immunoprecipitable by hyperimmune serum to ADRV, human ADRV convalescent serum, by a group B-specific monoclonal antibody and by porcine group B rotavirus infection serum. The baculovirus-expressed protein is immunogenic and antibodies to the expressed protein recognize ADRV virions. The ADRV VP6 protein should be useful for developing diagnostic assays for serum antibodies to group B rotavirus as well as for generating hyperimmune serum and monoclonal antibodies for detecting viral antigen from ADRV and other group B rotaviruses.
