<p>A fusion protein of porcine reproductive and respiratory syndrome virus (PRRSV) for PRRSV vaccine. The fusion protein includes: (a) a Pseudomoitas Exoloxin A (PE) peptide that comprises a binding domain and a translocating domain; (b) a peptide fragment that contains a N-terminal portion of PRRSV ORF6 protein; (c) a peptide fragment that has a N-terminal portion of PRRSV ORF5 protein; and (d) a carboxyl terminal domain that comprises an amino acid seciuence KDEL. The PE peptide is located at the N-terminus of the fusion protein, and the peptide fraament containinC the N-terminal portion of PRRSV ORF5 protein is located between the peptide fragment containing the N-terminal portion of PRRSV ORF6 protein and the carboxyl terminal domain.</p> |
