Fluorescence resonance energy transfer (FRET) technology is a useful tool to monitor protein interactions as well as protease activity. We have recently reported a biochemical assay utilizing a FRET reporter peptide to monitor the activity of the 20S catalytic particle (20S CP) of the proteasome. This assay is designed specifically to have increased sensitivity to identify stimulators of the 20S CP, which may hold therapeutic potential to treat protein-accumulation diseases. The protocol described here details the necessary steps in synthesizing the FRET reporter peptide and performing the FRET assay with the 20S CP. © 2018 by John Wiley & Sons, Inc.
荧光共振能量转移(FRET)技术是监测蛋白质相互作用以及蛋白酶活性的一种有用工具。我们最近报道了一种利用FRET报告肽监测蛋白酶体20S催化颗粒(20S CP)活性的生化检测方法。该检测方法经过专门设计,具有更高的灵敏度,可用于识别20S CP的刺激剂,这些刺激剂可能具有治疗蛋白质蓄积性疾病的潜在价值。此处描述的实验方案详细介绍了合成FRET报告肽以及用20S CP进行FRET检测的必要步骤。© 2018约翰威立国际出版公司
