GPCRs are the largest receptor family that are involved in virtually all biological processes. Pharmacologically, they are highly druggable targets, as they cover more than 40% of all drugs in the market. Our knowledge of biased signaling provided insight into pharmacology vastly improving drug design to avoid unwanted effects and achieve higher efficacy and selectivity. However, yet another feature of GPCR biology is left largely unexplored, location bias. Recent developments in this field show promising avenues for evolution of new class of pharmaceuticals with greater potential for higher level of precision medicine. Further consideration and understanding of this phenomenon with deep biochemical and molecular insights would pave the road to success. In this review, we critically analyze this perspective and discuss new avenues of investigation.
G蛋白偶联受体(GPCRs)是最大的受体家族,几乎参与所有生物过程。在药理学上,它们是高度可成药的靶点,因为市场上超过40%的药物都作用于它们。我们对偏向性信号传导的了解为药理学提供了深刻见解,极大地改进了药物设计,以避免不良影响并实现更高的疗效和选择性。然而,GPCR生物学的另一个特征——定位偏向性,在很大程度上仍未得到探索。该领域的最新进展为新型药物的研发展示了充满希望的途径,这类药物在精准医学方面具有更大的潜力。通过深入的生化和分子见解进一步思考和理解这一现象将为成功铺平道路。在本综述中,我们批判性地分析了这一观点并讨论了新的研究途径。
