Keywordsバイセクト型糖鎖 / NUP62 / 抗精子抗体 / 雄性生殖細胞
Outline of Research at the Start

糖鎖はタンパク質・核酸に続く第3の生命鎖として注目されているが、その分子構造は極めて多様性に富んでいるため機能解析は進んでいない。我々が樹立した抗マウス精子単クローン抗体Ts4は、バイセクト型N-アセチルグルコサミン構造を有する糖鎖を介して雄性生殖細胞に発現する複数の糖タンパク質を認識している。本研究ではこの糖鎖が修飾される糖タンパク質の同定と、生殖過程における本糖鎖構造の機能解明を目指す。

Outline of Final Research Achievements

We generated an anti-mouse sperm auto-monoclonal antibody, Ts4, which immmunoreacts to sevaral kinds of glycoproteins possessing N-linked fucosylated agalacto-biantennary with bisecting N-acetylglucosamine (GlcNAc) in male germ cells. We recently identified nuclear pore glycoprotein p62 (NUP62), a component of nuclear pore complexes with roles in nucleocytoplasmic transport as a Ts4-recognized glycoprotein during testicular development. To study mechanisms for regulating spermatogenesis by bisecting GlcNAc, we focused NUP62. We first established rabbit anti-mouse and human NUP62 polyclonal antibodies as molecular probes. Currently we are investigating the reactivity of antibodies using Western blotting and immunohistochemical analyses.

Academic Significance and Societal Importance of the Research Achievements

現在本邦では急速な少子化が深刻な問題となっている。一般に少子化は非婚化・晩婚化など社会科学的問題として認識されることが多いが、不妊症・不育症の増加など医学的な原因も無視できない。抗精子抗体が不妊症患者血清中に検出されることがあり、不妊の原因の一つである可能性が提唱されているが、その対応抗原や生物学的機能の詳細については依然不明である。我々が樹立した自己抗体由来の抗マウス精子抗体Ts4が認識する糖鎖とその修飾タンパク質の生物学的機能が明らかとなれば、本分子群を介した受精に関与する一連の分子機構の解明が進み、その結果、これまで原因不明であった不妊症治療のための分子基板を構築できる可能性がある。
