Outline of Final Research Achievements |
We found that SFT-4/Surf4 family proteins are required for endoplasmic reticulum (ER) exit of soluble cargo proteins including apolipoproteins in C. elegans and mammalian cultured cells. SFT-4/Surf4 family proteins localize to the ER exit sites and interact with apolipoproteins. These results suggest that SFT-4/Surf4 family proteins function as cargo receptors for soluble proteins in animals.

Academic Significance and Societal Importance of the Research Achievements |
本研究により,これまで不明であったリポタンパク質の分泌における新たな仕組みが明らかになるとともに,カイロミクロン停滞症のような脂質異常症の病因の解明にもつながることが期待されます.また,ヒトのSurf4は体内のコレステロール量を調節する新規薬剤のターゲットになる可能性があります.さらに,本研究により線虫がリポタンパク質の生合成及び分泌のメカニズムの解明やこれらを調節する薬剤探索をするのに有効なツールとして活用できることが明らかとなりました.
