| 摘要: |
| G蛋白偶联受体（G protein-coupled receptor, GPCR）是一个重要的细胞膜受体超家族。β-arrestin 1和β-arrestin 2是广泛存在于细胞内的调配器和支架蛋白,它们在G蛋白偶联受体的细胞内信号转导、脱敏、内化、复敏以及G蛋白非依赖的信号转导中发挥重要作用。生物发光共振能量转移（BRET）技术能够实时监测活细胞内GPCRs和β-arrestins的相互作用,可进一步阐明β-arrestin调节GPCRs的作用机制,有助于开发新一代影响GPCRs功能活动的药物。 |

| Abstract: |
| G Protein-coupled receptors constitute a super family of cell surface proteins. β-arrestin 1 and 2 are widely expressed intracellular adaptor and scaffolding proteins that play important roles in G protein-coupled receptor desensitization, internalization, intracellular traf?cking and G Protein-independent signalling. Recent developments in bioluminescence resonance energy transfer （BRET）technology enable monitor the GPCR–β-arrestin complexes in live cells and real time. In concert with a range of experimental tools, investigators can elucidate the ever-expanding roles of β-arrestins in mediating GPCR function, which will be benefit for developing new generation drugs targeting GPCRs. |
