Protein Expression of the Human Norovirus Capsid Gene using the Baculovirus Expression System

Abstract

Human norovirus (HuNoV) is the major etiological agent of nonbacterial gastroenteritis worldwide. However, due to the absence of a rapid and sensitive diagnostic system, detection and monitoring have been limited. The HuNoV genome is composed of three open reading frames (ORFs). And major capsid protein, ORF2, is designated as a viral protein 1 (VP1). In this study, the baculovirus expression system was used for expression of the HuNoV capsid protein, VP1. Recombinant baculoviruses can be used as potent tools in HuNoV studies.
