Abstract: It is intended to provide a protein complex and a production process whereby the protein complex can be efficiently produced without lowering its function. It is also intended to provide use of the protein complex in a biosensor, an immobilized enzyme and so on. A protein complex comprising a polyhedral protein having an insect virus encapsulated therein and a target protein having a restricted region of a capsid protein VP3 of cytoplasmic polyhedrosis virus, more specifically, a region which is either a region from the N-terminus to the 40th amino acid residue or a region from the 41st amino acid residue to the 79th amino acid residue as an embedding signal for polyhedron, and a process for producing the same. The polyhedral protein has an effect on improvement in the stability of the target protein, protection thereof or improvement in the preservation properties thereof, or a combination thereof.

Abstract: To provide a useful objective protein coated with a protective protein, a protein complex that is produced in cells and has a structure that the objective protein is occluded with the viral occlusion body protein. A protein complex having the structure that the objective protein is occluded with the viral occlusion body protein, produced in insect cells or plant cells, preferably produced by incorporation of the objective protein in the crystalline form during crystallization of polyhedron derived from polyhedrosis virus, preferably a protein complex in which the polyhedrin contributes to improvement of stability, or protection, or improvement of preservability, or combination thereof, of the objective protein.
