Rab7是属于Rab家族的小GT3,控制转运至晚期内吞隔室,如晚期内体和溶酶体。Rab7在晚期内吞途径中的作用机制已被广泛研究。Rab7是溶酶体生物发生、定位和功能的基础,也是几种信号受体的运输和降解的基础,因此也对信号转导具有影响。已经鉴定了几种Rab7相互作用蛋白,除了其在内吞作用中的既定作用之外,还发现了许多不同的重要功能。此外,Rab7在神经元中具有特定的功能。本文综述了Rab7在不同细胞通路和过程中的作用和重要性。
Rab7 is a small GTPase that belongs to the Rab family and controls transport to late endocytic compartments such as late endosomes and lysosomes. The mechanism of action of Rab7 in the late endocytic pathway has been extensively studied. Rab7 is fundamental for lysosomal biogenesis, positioning and functions, and for trafficking and degradation of several signaling receptors, thus also having implications on signal transduction. Several Rab7 interacting proteins have being identified leading to the discovery of a number of different important functions, beside its established role in endocytosis. Furthermore, Rab7 has specific functions in neurons. This review highlights and discusses the role and the importance of Rab7 on different cellular pathways and processes.
