PNAS | 人源甲状旁腺激素受体2复合物三维结构成功解析
2021年8月6日(北京时间),由中国科学院上海药物研究所王明伟/杨德华团队和徐华强/赵丽华团队携手蒋华良/程曦团队于《美国国家科学院院刊》(Proceedings of the National Academy of Sciences of the United States of America)在线发表了题为“Molecular insights into differentiated ligand recognition of the human parathyroid hormone receptor 2”的研究成果。这篇由2012年诺贝尔化学奖得主Robert J. Lefkowitz教授主审的直投(PNAS Direct Submission)论文首次报道了人源甲状旁腺激素受体2(Parathyroid hormone receptor 2, PTH2R)与其内源性配体和Gs蛋白复合物的冷冻电镜结构,揭示了PTH2R的配体选择性、拮抗作用及疾病发生的分子机制,为相关新药的研发奠定了坚实的基础。
