胆汁淤积性瘙痒是肝脏疾病的一种严重和使人衰弱的症状,治疗选择有限。A类G蛋白偶联受体(GPCR)Mas相关GPCR亚型X4(MRGPRX 4)已被鉴定为胆汁酸的受体,胆汁酸是潜在的胆汁淤积性促胆汁生成剂。越来越多的GPCR已被证明与受体活性修饰蛋白(RAMP)相互作用,这可以调节GPCR生物学的不同方面。使用多重免疫测定和邻位连接测定的组合,我们表明MRGPRX 4与RAMP相互作用。MRGPRX 4与RAMP 2(而非RAMP 1或3)的相互作用导致基础和激动剂依赖性信号转导减弱,这与使用定量NanoBRET脉冲追踪测定测量的MRGPRX 4细胞表面表达降低相关。最后,我们使用AlphaFold多聚体来预测MRGPRX 4-RAMP 2复合物的结构。RAMP 2调节MRGPRX 4的发现可能对未来胆汁淤积性瘙痒的药物开发有直接影响。
Cholestatic itch is a severe and debilitating symptom in liver diseases with limited treatment options. The class A G protein-coupled receptor (GPCR) Mas-related GPCR subtype X4 (MRGPRX4) has been identified as a receptor for bile acids, which are potential cholestatic pruritogens. An increasing number of GPCRs have been shown to interact with receptor activity–modifying proteins (RAMPs), which can modulate different aspects of GPCR biology. Using a combination of multiplexed immunoassay and proximity ligation assay, we show that MRGPRX4 interacts with RAMPs. The interaction of MRGPRX4 with RAMP2, but not RAMP1 or 3, causes attenuation of basal and agonist-dependent signaling, which correlates with a decrease of MRGPRX4 cell surface expression as measured using a quantitative NanoBRET pulse-chase assay. Finally, we use AlphaFold Multimer to predict the structure of the MRGPRX4–RAMP2 complex. The discovery that RAMP2 regulates MRGPRX4 may have direct implications for future drug development for cholestatic itch.
