G蛋白偶联受体(GPCRs)是一个质膜蛋白超家族,在内分泌、神经和感觉信号的传递中起着重要作用。在人类中,30多种疾病与GPCRs的突变有关,这些蛋白质是常见的药物开发靶点,30%-50%的药物针对它们。GPCR突变体经常被错误折叠,被细胞质量控制系统识别为有缺陷,保留在内质网中,不运输到质膜。利用小分子伴侣(药理伴侣或药物操纵子)来挽救错误折叠的GPCRs,为治疗因错误折叠和错路而引起的人类疾病提供了一种新的途径。本章概述了这种方法的分子基础,使用人促性腺激素释放激素受体(HGnRHR)作为模型来治疗由错误折叠的GPCRs引起的构象疾病。
G-protein-coupled receptors (GPCRs) are a large superfamily of plasma membrane proteins that play central roles in transducing endocrine, neural and sensory signals. In humans, more than 30 disorders are associated with mutations in GPCRs and these proteins are common drug development targets, with 30–50% of drugs targeting them. GPCR mutants are frequently misfolded, recognized as defective by the cellular quality control system, retained in the endoplasmic reticulum and do not traffic to the plasma membrane. The use of small molecules chaperones (pharmacological chaperones or “pharmacoperones”) to rescue misfolded GPCRs has provided a new approach for treatment of human diseases caused by misfolding and misrouting. This chapter provides an overview of the molecular basis of this approach using the human gonadotropin-releasing hormone receptor (hGnRHR) as model for treatment of conformational diseases provoked by misfolded GPCRs.
