摘要: A fusion protein that is expressed in a recombinant protein body-like assembly (RPBLA) in host eukaryotic cells and organisms is disclosed. More particularly, a biologically active polypeptide fused to a protein sequence that mediates the induction of RPBLA formation is expressed and accumulated in host cells after transformation with an appropriate vector. The eukaryotic host cell does not produce protein bodies in the absence of the fusion protein. Methods for preparing and using the RPBLAs and the fusion protein are also disclosed, as are nucleic acid molecules that encode the fusion proteins.

摘要: Polypeptide sequences for inducing recombinant protein bodies are described. The sequences comprise a polyproline II (PPII) structure between two cysteine residues on either end and an ER signal sequence Recombinant protein bodies are useful for protein production because they allow for simple and efficient purification of high quantities of recombinant protein.In addition, other methods of using recombinant protein bodies, for example, in vaccination, are also described.
