硫氧还蛋白(Trx)是生命系统中主要的硫醇依赖抗氧化剂之一。由于缺乏实用的工具来跟踪活细胞中的TRX氧化还原动力学,阻碍了TRX在氧化还原生物学中的功能的研究。我们之前的工作开发了TrxRFP1,这是第一个用于TRX氧化还原的遗传编码荧光指示剂。在这项工作中,我们报告了一个改进的荧光指示剂TrxRFP2,用于跟踪Trx1的氧化还原,它主要是胞质和细胞核的。此外,由于线粒体专门表达Trx2,我们创造了一个新的遗传编码的荧光指示剂MtrxRFP2,用于线粒体Trx的氧化还原。我们将MtrxRFP2鉴定为纯化蛋白,并使用亚细胞定位的MtrxRFP2来成像活细胞中线粒体氧化还原的变化。
Thioredoxin (Trx) is one of the major thiol-dependent antioxidants in living systems. The study of Trx functions in redox biology was impeded by the lack of practical tools to track Trx redox dynamics in live cells. Our previous work developed TrxRFP1, the first genetically encoded fluorescent indicator for Trx redox. In this work, we report an improved fluorescent indicator, TrxRFP2, for tracking the redox of Trx1, which is primarily cytosolic and nuclear. Furthermore, because mitochondria specifically express Trx2, we have created a new genetically encoded fluorescent indicator, MtrxRFP2, for the redox of mitochondrial Trx. We characterized MtrxRFP2 as a purified protein and used subcellularly localized MtrxRFP2 to image mitochondrial redox changes in live cells.
