Abstract

Human sapovirus (SaV) strains are agents of gastroenteritis. They cannot be grown in cell culture. In this study, constructs containing SaV N- and C-terminal-deleted recombinant capsid proteins (rVP1) were expressed in a baculovirus expression system to allow us to better understand the sequence requirements for the formation of virus-like particles (VLPs). Only proteins derived from N-terminal-deleted rVP1 constructs that began 49 nucleotides downstream assembled into VLPs, which included both small and native-size VLPs. Our results were similar to those reported in a rabbit hemorrhagic disease virus (RHDV) N- and C-terminal-deleted rVP1 expression study but were distinct from those reported in a norovirus N- and C-terminal-deleted rVP1 expression study, suggesting that SaV and RHDV may have similar expression requirements.
