In this issue of Cell, two papers report agonist-bound cryo-EM structures of the cannabinoid receptor, CB2, in complex with Gi. Importantly, beyond providing information that could help distinguish CB2 ligand binding from CB1, these structures support the existence of a nucleotide-free state during G-protein signaling.
在本期《细胞》杂志中，两篇论文报道了大麻素受体CB2与Gi复合物的激动剂结合冷冻电镜结构。重要的是，这些结构不仅提供了有助于区分CB2与CB1配体结合的信息，还支持了G蛋白信号传导过程中无核苷酸状态的存在。
