蛋白质-DNA相互作用的研究为理解基因的功能和调控提供了重要的信息,但识别和验证特定的相互作用仍然是后基因组时代的主要挑战。因此,有效而经济的方法来评估蛋白质-DNA相互作用一直是分子生物学家所追求的,选择合适的方法来检测特定的蛋白质-DNA相互作用也是研究人员面临的一个关键挑战。自20世纪70年代以来,人们根据不同的原理,结合不同的修饰,发展了许多研究蛋白质-DNA相互作用的方法和变体。在这一点上,我们总结了最常用的评估蛋白质-DNA相互作用的方法,以便研究人员可以一目了然地检查每种方法的优缺点,并选择适当的技术来研究感兴趣的生物过程(表1)。根据不同的原理,蛋白质-DNA相互作用的方法可以分为四类:
Investigation of protein-DNA interactions provides important information for understanding gene function and regulation, but identification and validation of specific interactions remain major challenges in the post-genomics era. Therefore, effective and economical methods to assess protein-DNA interactions are highly sought-after by molecular biologists.Choosing the appropriate method to examine a specific protein-DNA interaction also remains a crucial challenge for researchers. Since the 1970s, many methods and variants have been developed to study protein-DNA interactions based on different principles and incorporating different modifications. In this insight, we summarize the most commonly used methods for assessing protein-DNA interactions, so researchers can examine the strengths and weaknesses of each method at a glance and choose an appropriate technique to study the biological processes of interest (Table 1). The methods for protein-DNA interactions can be categorized into four types based on different principles:
