Research Abstract

(1)FKBP38ノックアウトマウスにおける異常およびRabの関与の解析
FKBP38とRabとの機能的連関を解析する。FKBP38ノックアウトマウスにおけるRabの発現パターンを解析した。また、FKBP38ノックアウトマウス細胞抽出液を用いて、Rab23活性を測定する。FKBP38ノックアウト細胞を用いて、細胞内膜輸送について検討した。
(2)ProtrudinとRabおよび膜輸送との機能的連関の解析
Rabとprohudinとの機能的連関を解析する。Protrudinはマルチドメインタンパク質であるが、変異protrudinを作製し、ドメイン機能解析を行う。また、変異protrudinのRab結合能、Rab制御能、細胞内局在、膜輸送、神経突起形成能などに関して解析した。
(3)ProtrudinノックアウトマウスにおけるRab活性、膜輸送、神経突起伸長の解析
マウス個体におけるRab制御と神経突起形成との関係を解析するために、protrudinノックアウトマウスを作製し、Rabllや他のRabについて発現パターンの変化を解析した。また、protrudinノックアウトマウス細胞抽出液を用いて、Rab活性を測定した。また、各種神経突起マーカーを用いて神経突起形成に関して詳細に観察した。Protrudinノックアウト細胞を用いて、細胞内膜輸送に異常がないか検討した。Protrudinノックアウトマウスで神経管形成に異常がないか解析した。
