FUSION PROTEIN CAPABLE OF SELF-ASSEMBLY BY COMPRISING PURIFICATION TAG AND A-HELIX TAG, AND METHOD FOR PURIFYING RECOMBINANT PROTEIN BY USING SAME

Abstract

The present invention relates to a fusion polypeptide and a method for purifying a target protein by using same, the polypeptide having any one from among a His tag, a HAT tag and an HQ tag, and an α-helix peptide tag of which the major amino acids are charged and hydrophobic amino acids. Since the fusion polypeptide has an ability to induce self-assembly by being fused with the target protein, the target protein purification method using same enables the isolation and purification of the target protein merely through very simple processes such as centrifugation or filtration.
