摘要

Rab蛋白是Ras超家族成员,是一类小分子GTP结合蛋白。在大分子物质进入细胞的内吞途径和细胞器间的物质转运过程中,Rab蛋白通过招募其效应蛋白可作用于囊泡形成、转运、黏附和融合,是囊泡运输过程中的关键调节因素。Rab蛋白及其效应蛋白定位和功能的改变与多种疾病相关。本文就Rab蛋白的主要功能及其在帕金森病、阿尔茨海默病、亨廷顿病等神经退行性疾病发生与发展过程中的作用进行综述。

Abstract

As a member of the Ras superfamily, Rab proteins are small GTP-binding proteins. In the process of endocytosis of macromolecules and substances delivery between organelles, Rab proteins act on vesicle formation, transport, tethering and fusion by recruiting their effectors, therefore being key regulatory factors in vesicle trafficking. Disturbance of localizations and functions of Rab proteins and their effectors are involved in the pathogenesis of several diseases. This review focuses on the main functions of Rab proteins and their possible roles in the onset and progression of neurodegenerative diseases including Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease.


Key words: Rab proteins; neurodegenerative diseases; α-synuclein; amyloid β-protein; Tau; Huntington protein
