| Outline of Final Research Achievements |
Antibodies are used in many research fields as useful tools. However, it is not so easy to produce antibodies that are useful for basic life science or clinical medicine in many cases. It has been suggested that the ribosomal P protein complex has unique structural features responsible for induction of anti-P autoantibody. In this study, I genetically added several kinds of amino acid sequences into a site of the P protein and immunized rabbits with the isolated chimeric proteins. As the results, I succeeded in producing site-specific antibodies, whose target sites were genetically induced to the P protein. So far, I detected productions of the following antibodies using this technique: antibodies to ribosomal protein S6, translation factor Hbs1, and Zucchine, an important factor involved in RNA interference. The results indicate that this technique could be used for productions of a variety of site-specific antibodies.
