帕金森病 (PD) 是一种进行性神经系统疾病,临床表现为运动改变以及多种非运动症状,包括但不限于认知和自主神经异常。编码泛素 E3 连接酶 Parkin 的基因的功能丧失突变是家族性和青少年 PD 的病因。在正在探索的治疗帕金森病或改善帕金森病患者预后的几种治疗方法中,使用能够恢复或增强 Parkin 活性的小分子代表了一种潜在的药物治疗策略。一个主要障碍是缺乏高通量平台来对 Parkin 活性进行稳健和准确的体外定量。在这里,我们提出了两种不同且互补的基于基质辅助激光解吸/电离飞行时间质谱 (MALDI-TOF/MS) 的方法,用于体外量化 Parkin E3 连接酶活性。这两种方法都可扩展用于高通量初级筛选,以促进 Parkin 调节剂的识别。
Parkinson's disease (PD) is a progressive neurological disorder that manifests clinically as alterations in movement as well as multiple non-motor symptoms including but not limited to cognitive and autonomic abnormalities. Loss-of-function mutations in the gene encoding the ubiquitin E3 ligase Parkin are causal for familial and juvenile PD. Among several therapeutic approaches being explored to treat or improve the prognosis of patients with PD, the use of small molecules able to reinstate or boost Parkin activity represents a potential pharmacological treatment strategy. A major barrier is the lack of high-throughput platforms for the robust and accurate quantification of Parkin activityin vitro. Here, we present two different and complementary Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF/MS)-based approaches for the quantification of Parkin E3 ligase activityin vitro. Both approaches are scalable for high-throughput primary screening to facilitate the identification of Parkin modulators.
