| 摘 要： | 膜泡运输是不同细胞器间进行物质传递的基本方式,分为4个重要步骤：囊泡的出芽、转运、拴系和融合。在此过程中,有许多相关因子参与调控,如包被蛋白、Rab蛋白、拴系因子、SM蛋白和SNARE等。拴系因子在运输囊泡和靶位膜发生接触的最初阶段起重要调控作用,多数拴系因子形成大的多亚基复合体发挥功能。目前,关于拴系因子的功能已经有了一定的了解,在此,我们对酵母、哺乳动物以及植物细胞中的已知拴系因子的特点和功能进行了概述。

| Abstract: | Intracellular delivery of materials between different organelles is mostly based on vesicle transport.Each vesicle transport reaction can be divided into four essential steps including vesicle budding,transport,tethering and fusion.These steps are tightly regulated by many factors,such as coat proteins,SM,SNARE,Rab proteins and tethering factors.Tethering factors function in the initial attachment of transport vesicles to their target membranes.Most of the tethering factors are large multisubunit complexes.Up to date,there are certain achievements on study of tethering factor.This review summarizes developments in characterization and function of tethering factors in yeast,mammalian and plant cells. |
