Description

Infectious pancreatic necrosis virus (IPNV), a birnavirus, is an important pathogen in fish farms. Analyses of viral proteins showed that VP2 is the major structural and immunogenic polypeptide of the virus [PMID: 8525637, PMID: 17976679]. All neutralizing monoclonal antibodies are specific to VP2 and bind to continuous or discontinuous epitopes. The variable domain of VP2 and the 20 adjacent amino acids of the conserved C-terminal are probably the most important in inducing an immune response for the protection of animals [PMID: 8525637].

The large RNA segment of the Birnaviridae codes for a polyprotein (N-VP2-VP4-VP3-C), most of which is then processed to generate the constituent polypeptides. VP4 protein is involved in generating VP2 and VP3 [PMID: 2828658]. Recombinant VP3 is more immunogenic than recombinant VP2 [PMID: 15669113].
