Outline of Final Research Achievements

Candidates of amino acid sequences was screened from the Protein Data Bank in terms of intermolecular and intramolecular contacts. We identified 35 peptides and examined their interaction stability by using canonical and multicanonical molecular dynamics simulations. We obtained three pairs of peptides with weak interactions. We synthesized these peptides, and their interactions were examined with the fluorescence correlation spectroscopy. In preliminary results of this experiment, we confirmed that at least one designed peptide pair interacted. We have published 15 articles (14 of them were peer reviewed), performed 50 presentations in conferences, wrote 1 book, submitted 1 domestic patent.

Academic Significance and Societal Importance of the Research Achievements

くすりの開発には多くの費用と時間が必要となる。特に最近では「ペプチド」と呼ばれる小さなたんぱく質から成るくすりの開発が重要になっているが、正しく機能するペプチドを設計することは容易ではない。この研究では、これまでに明らかにされてきた全てのたんぱく質のデータを調べ、その中から一部分を切り取ることで、機能するペプチドの開発を行った。その結果、ペプチドが一定の機能をもつことが試験管内での実験によって確認できた。現状ではくすりそのものが作れたわけではないが、そのための第一歩を達成できたと言える。新しいくすりを効率的に開発する方法となる可能性を示すことができ、その社会的意義は高い。
