Outline of Final Research Achievements

In this study, I aimed at revealing the molecular function of eEF1BdeltaL protein in nuclear and elucidating how the deletion of this protein led to epileptic seizure in mice. For its purpose, I visited to the foreign researcher who specializes in nuclear proteins and obtained following results. 1) All proteins which constitute eEF1 complex exist in both cytosol and nucleus. 2) eEF1BdeltaL could form a complex with RNA-binding proteins. 3) By ChIP sequencing, it was found that eEF1BdeltaL could bind to some genes in X chromosome.

Academic Significance and Societal Importance of the Research Achievements

eEF1BδLは翻訳伸長因子のスプライシングバリアントであり、本来の機能と異なり、核内にて転写を刺激する機能をもつ非常にユニークなタンパク質である。本機能を解明することは生命科学分野において意義のあることである。さらにeEF1BδLの変異が神経発達障害の原因として同定されており、本タンパク質の分子レベルでの機能制御を明らかにすることは創薬など薬学分野や医学分野においても有意義な研究である。
