G protein-coupled receptors (GPCRs) constitute a superfamily of cell surface receptors that regulate a variety of cell functions. As the cell surface is the functional destination for most GPCRs, the cell surface targeting process represents a crucial checkpoint in controlling the functionality of the receptors. However, the molecular mechanisms underlying the cell surface delivery of newly synthesized GPCRs remain poorly understood. In this review, we will highlight the role of Rab GTPases in GPCR cell surface transport, particularly post-Golgi traffic, and discuss the underlying molecular mechanisms.
G蛋白偶联受体(GPCRs)构成了一类细胞表面受体超家族,可调节多种细胞功能。由于细胞表面是大多数GPCR的功能目的地,细胞表面靶向过程是控制受体功能的关键检查点。然而,新合成的GPCR细胞表面递送的分子机制仍知之甚少。在本综述中,我们将重点介绍Rab GTPases在GPCR细胞表面运输中的作用,特别是高尔基体后运输,并讨论其潜在的分子机制。
