Outline of Final Research Achievements

Voltage-sensing phosphatase is a unique protein that transduces electrical signal in membrane into chemical signal. Despite its robust and deep understandings of molecular mechanisms, physiological function of VSP has remained unclear. In this study, we analyzed sperm of VSP deficient mouse by combining electrophysiology, fluorescence measurement, molecular dynamics simulation and mass spectrometry. VSP regulates potassium channel activity on sperm flagellum membrane via regulating the level and distribution of PI(4,5)P2. This is the first report on identification of physiological role of VSP in any animal species. It also gives the first case where the absolute level and distribution of phosphoinositide in sperm was shown to be critical for regulation of cellular function.

Academic Significance and Societal Importance of the Research Achievements

これまで膜電位シグナルは、イオンチャネルの分布により規定されるということが教科書的な概念であったが、今回のVSPによるイノシトールリン脂質の分布によるイオンチャネルの制御の発見は、この固定概念を覆し、イオンチャネルの分布に加えて、脂質分子の分布が重要であることを初めて明らかにしたもので、その学術的な意義は大きい。VSPは動物種を超えて精子に発現しており、今回初めて明らかになった脂質分子の役割の理解を今後更に進めることで、不妊症の解決や創薬などを通して少子化社会の問題に資する可能性があるとともに、畜産などでの生殖技術や動物種多様性の保全などにむけた研究の基礎に資する可能性がある。
