Outline of Final Research Achievements

Ci-YFV-1, 2, 3, and Ci-YFL are novel Ciona-specific neuropeptides. Their cognate receptors and biological roles remained to be elucidated. In this study, we develop an original machine learning system to predict specific interaction between neuropeptides and receptors, and evauluated the predicted results. The cell-based funtional assays led to the elucidation of specific receptors for Ci-YFV-1 reeptor and Ci-YFV-3 receptors were found to be expressed in the central nervous system and atrial siphon. Furthermore, the former was also expressed specifically in the endostyle, whreas specific expression of the latter was detected in the oral siphon.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、これまで全く不明だったホヤ特異的な神経ペプチドやペプチドホルモンの生物学的な役割を解明することや、神経系や内分泌系がどのように進化・多様化してきたかをという、生物の本質的な問いに答える研究に展開できることが期待できます。さらに、本研究で開発した機械学習システムを活用することで、ヒトをはじめとする生物に存在する神経ペプチドやペプチドホルモンの受容体を高い確率で、そして、短時間で予測することが可能となり、これまで知られていなかったペプチド‐受容体の相互作用の法則を解明し、その成果を創薬に応用できます。
