キーワード	鞭毛・繊毛運動 / 精子運動調節 / 滑り運動 / ダイニン / チューブリン / プロテアソーム / シグナルトランスダクション / タンパク質リン酸化
研究概要	鞭毛運動の基本機構に関しては、主に、ダイニンとチューブリンの生理生化学的研究が中心に行われ、高橋・真行寺はウニ除膜精子に強制振動を加え、様々なATP濃度での微小管滑り速度を測定し、滑り速度は必ずしもATP濃度で決定されない事を、豊島は、ウニ精子ATPaseにはDバンドダイニン重鎖を含み、ATP濃度依存的に微小管運動を阻害、回転、並進と様々に調節する事を示した。クラミドモナスで神谷はダイニンの再構成に成功し、その過程で新しいタンパク質の関与を発見した。再に、小川は細胞質ダイニンのcDNAクローニングを行い、β重鎖のCドメインに20%類似の者を得た。比較生化学的には、軟体動物精子鞭毛ダイニンは原腸体腔幹に属する者と同様2頭構造である事が示された(毛利)。中村はチューブリンアイソフォームの内α_5,β_3が可溶化され易い軸糸内微小管に存在する事を示した。精子の運動調節に関しては、運動開始機構・活性化・走化性について研究が進み、最近の話題をとなっているプロテアソームについて、稲葉はそれをサケ精子から精製し、精子鞭毛に局存し鞭毛運動を調節している事を明らかにした。森沢は、精子運動開始機構におけるシグナルトランスダクション機構解明を進めると共に、ニシンとホヤで精子活性化、走化性機構解明に向けて研究を進め、各々の過程で活性化走化性物質の精製を進めた。哺乳類では、マウス精子の運動開始にはHCO_3^-,Ca^<2+>,cAMP存在の65KDペプチドのリン酸化が関与している事が示された(奥野)。また馬場は、CA^<2+>が鞭毛波の伝播を担うオシレーターに特異的に作用する事をみつけた。繊毛運動の調節に関しては、ゾウリムシで繊毛打方向を制御するタンパク質の電気泳動による分離を試みた結果、22Sダイニンの重鎖が候補として浮かび上がってきた(野口)。また、ゾウリムシの繊毛打運動は、細胞体膜部から流入するCa電流によって活性化される事が明らかとなった。(中岡)。
