【Abstract】 Membrane protein plays an important role in various biological process. Modulation the structural and functional property of membrane protein would help to clarify the fundamental molecular mechanisms and provide basis for drug discovery and efficient therapeutic strategy. Aptamer is a special kind of oligonucleotide which can bind to its target efficiently. Due to its unique properties,aptamer is widely used in biosensing application. As a biological material,DNA molecule possesses the advantages of programmable design and facile functionalization. Thus,the combination of aptamer with DNA nanotechnology would provide a powerful tool for studying the interactions between membrane proteins. This review summarizes the recent research progress on aptamer-targeted membrane protein recognition and functional regulation utilizing DNA nanotechnology.The promising prospects and challenges in the future application of aptamer-targeted membrane protein recognition and functional regulation are also highlighted.更多还原
