Luciferase reporter assays are widely used to study promoter activity, transcription factors, intracellular signaling, protein interactions (Jia et al., PloS One 6:e26414), miRNA processing (Allegra and Mertens, Biochem Biophys Res Commun 406:501-505), and target recognition (Jin et al., Methods Mol Biol 936:117-127). Here we describe the use of a dual-luciferase reporter system to evaluate the enzymatic activity of a key enzyme involved in RNA maturation-DROSHA. This dual system is a simple and fast method for the quantification of the DROSHA processing activity in live cells.
荧光素酶报告基因检测被广泛用于研究启动子活性、转录因子、细胞内信号传导、蛋白质相互作用(Jia等人,《公共科学图书馆·综合》6:e26414)、微小RNA加工(Allegra和Mertens,《生物化学与生物物理研究通讯》406:501 - 505)以及靶标识别(Jin等人,《分子生物学方法》936:117 - 127)。在此,我们描述了使用双荧光素酶报告基因系统来评估参与RNA成熟的关键酶——DROSHA的酶活性。这个双系统是一种简单快速的方法,用于定量活细胞中DROSHA的加工活性。
