摘要:

G蛋白偶联受体(G protein-coupled receptors, GPCRs)作为最大的一类膜蛋白受体家族,可被多种配体激活并发挥相应的信号转导功能,参与生物体内重要的生理过程。G蛋白偶联受体相关分选蛋白(G protein-coupled receptors associated sorting proteins, GASPs)则对内吞后的GPCRs分选过程发挥着重要的作用,并介导受体进入降解或再循环途径,进而调控细胞的信号转导等过程。研究发现GASPs的功能缺陷与多种疾病相关,包括神经系统疾病、肿瘤和耳聋等。本文重点介绍了G蛋白偶联受体相关分选蛋白的功能特征及其相关信号通路,描述了GASPs功能缺陷与疾病的关联性及家族蛋白与GPCRs的相互作用、GASPs分选途径的发现、参与的信号通路及对基因转录调控,以期为GASPs相关多种疾病的治疗提供新的思路和策略。

Abstract:

G protein-coupled receptors (GPCRs), the largest family of membrane protein receptors, can be activated by a variety of ligands and participate in signaling transduction, and they are essential in the physiologic process in vivo. GPCR-associated sorting proteins (GASPs) play an important role in the post-endocytic sorting of GPCRs. They mediate the degradation or recycling pathway, and regulate cell signaling transduction and other biological processes. The functional defects of GASPs have been reported to be implicated in pathogenesis of some neurological diseases, tumors and deafness and so on. In this review, we summarize the GASPs’ function, GPCR-GASP interactions, GPCR sorting pathway and GASP-related signaling pathways implicated in the transcriptional regulation. It could help to understand the potential linkage between GASPs’ dysfunction and diseases, and provide a new approach and strategy for the treatment of GASP-related diseases.

Key words: G protein-coupled receptors (GPCRs), G protein-coupled receptor-associated sorting proteins (GASPs), signal transduction, disease
