| Research Abstract |
The development of techniques for immobilizing proteins with retaining their functions even on a solid surface is important. However, it is difficult to control the orhentation of protein on a solid-surface. To overcome this disadvantage, we have proposed a novel technique for assembling functional proteins. It is based on a simple hydrophobic intetaction between protein and solid-surface. In this method, a target protein is fused with a hydrophobic peptide unit, which has an ability to assemble on a hydropbobic solid-surface. In this condition, a relatively hydrophilic target protein part in the fusion protein sbould be oriented to the opposite side of solid-surface. Therefore, it is expected to realize a simple and efficient method for assembling functional proteins. We have designed novel proteins consisting of hydrophobic peptide sequence as a self-assembled structural unit and molecular recognition peptide as a functional unit. The resulting proteins retained their functions on a solid-phase surface and they were applied to biocensing and cellular engineering.
