Research Abstract

(1)FKBP38ノックアウトマウスの形態異常・神経細胞異常の詳細な観察
FKBP38ノックアウトマウスの脳や脊髄において、神経細胞突起の異常な伸長が認められた。FKBP38ノックアウトマウスの中枢神経系において、異常のある神経細胞の種類、分化段階、領域を特定した。
(2)FKBP38ノックアウトマウスにおける膜輸送関連分子の解析
発生期の神経管形成に膜輸送制御分子であるRabの異常が関係することが知られている。そこで、FKBP38ノックアウトマウスにおけるRabの発現パターン、Rabタンパク質量の変化などを解析する。さらに、Rabタンパク質のユビキチン化、プロテアソーム依存的分解について解析した。
(3)ProtrudinとRabとの関係の解析
FKBP38とprotrudinによる膜輸送制御の作用機構を検討する。Protrudinドメイン解析などを行い、Rabとの機能的関連、リン脂質との機能的関連、Rabタンパク質のプロテアソーム依存的分解などについて検討した。さらに、膜輸送との関係について検討した。
(4)Protrudinノックアウトマウス作製とFKBP38及び膜輸送への関与の解析
Protrudmノックアウトマウスを作製し、神経管形成、FKBP38やRabや膜輸送について解析した。
