G蛋白偶联受体(GPCR)是最大的一类膜受体,在神经传递和免疫反应等多种过程的调节中发挥关键作用。GPCR寡聚化的证据不断积累,挑战了GPCR仅作为单体受体发挥作用的观点;然而,GPCR寡聚化仍然存在争议,主要是由于难以比较来自非常不同类型的结构和动态数据的证据。使用单分子和合奏FRET,双电子-电子共振光谱和模拟的组合,我们表明,GPCR神经降压素受体1的二聚化受受体密度的调节,并在生理范围内动态可调。我们提出了一个“滚动二聚体”界面模型,其中多种二聚体构象共存和相互转换。这些发现结合了以前似乎相互矛盾的观察结果,为调节受体信号提供了一个令人信服的机制,并为未来的生理学研究提供了指导。有证据表明G蛋白偶联受体在细胞膜上的寡聚化,但这是有争议的。在这里,作者使用单分子和合奏FRET和光谱显示,神经降压素受体1形成多个二聚体构象相互转换-“滚动”接口。
G protein-coupled receptors (GPCRs) are the largest class of membrane receptors, playing a key role in the regulation of processes as varied as neurotransmission and immune response. Evidence for GPCR oligomerisation has been accumulating that challenges the idea that GPCRs function solely as monomeric receptors; however, GPCR oligomerisation remains controversial primarily due to the difficulties in comparing evidence from very different types of structural and dynamic data. Using a combination of single-molecule and ensemble FRET, double electron–electron resonance spectroscopy, and simulations, we show that dimerisation of the GPCR neurotensin receptor 1 is regulated by receptor density and is dynamically tuneable over the physiological range. We propose a “rolling dimer” interface model in which multiple dimer conformations co-exist and interconvert. These findings unite previous seemingly conflicting observations, provide a compelling mechanism for regulating receptor signalling, and act as a guide for future physiological studies. Evidence suggests oligomerisation of G protein-coupled receptors in membranes, but this is controversial. Here, authors use single-molecule and ensemble FRET, and spectroscopy to show that the neurotensin receptor 1 forms multiple dimer conformations that interconvert - “rolling” interfaces.
