描述(申请人提供)：大麻素2型受体(CB2R)是治疗神经性疼痛和其他几种疾病的靶点。解决CB2R的三维结构将使设计更好的CB2R选择性药物成为可能。尽管目前市场上的所有治疗药物中有30%-50%调节不同的G蛋白偶联受体(GPCRs)的作用，但视紫红质是唯一已知晶体结构的GPCRs。结晶学所需的大量高质量受体样品的制备一直是制约GPCR结晶的瓶颈。本项目的目的是利用一种新颖的、专有的表达系统来产生大量同源的CB2R，从而对CB2R进行结晶和结构鉴定。如果成功，CB2R结构将极大地增强我们目前的大麻素受体药物发现工作。此外，该结构将代表第一个非视紫红质模板，用于家族1 GPCRs的分子建模。特别是，它将是一个很好的模板，用于建立密切相关的CB1R的模型，涉及许多治疗领域，包括药物滥用、免疫紊乱和肥胖。

英文摘要

DESCRIPTION (provided by applicant): The cannabinoid type 2 receptor (CB2R) is a target for the treatment of neurophatic pain and several other disorders. Solving the 3-dimensional structure of CB2R would enable the design of better CB2R-selective drugs. Although 30-50% of all current therapeutic drugs on the market modulate the action of different G protein coupled receptors (GPCRs), rhodopsin is the only GPCR for which the crystal structure is known. The bottleneck for GPCR crystallization has been the difficulty to generate large quantities of high-quality receptor sample needed for crystallography. The aim of this project is the crystallization and structural elucidation of CB2R by taking advantage of a novel, proprietary expression system to generate large amounts of homogeneous CB2R. If successful, the CB2R structure would dramatically empower our current cannabinoid receptor drug discovery effort. Moreover, this structure would represent the first non-rhodopsin template for molecular modeling of Family 1 GPCRs. And, in particular, it would be an excellent template for the modeling of the closely related CB1R, involved in many therapeutic areas including drug abuse, immune disorders, and obesity.
