ABSTRACT
Rhodopsin-like G protein-coupled receptors (GPCRs), widely distributed in microorganisms, invertebrates, and vertebrates, are the largest class in GPCRs, and are involved in many important physiological and pathological processes, including the photosensitivity, regulation of behavior and emotion, and so on. Atomic force microscopy (AFM) is a powerful and multifunctional toolkit in bionanotechnology, as it can image the morphology of membrane proteins at subnanometer spatial resolution and detect forces related with membrane proteins down to piconewton level by single-molecule force spectroscopy (SMFS) mode under physiological conditions. Herein, the achievements of AFM in the study of rhodopsin-like GPCRs, including observing the high-resolution topography and structural changes, revealing the interaction forces, binding kinetics, and mechanical properties (such as modulus), are reviewed and summarized. Finally, the challenges, outlook, and prospects of AFM in the study of rhodopsin-like GPCRs are discussed.
