Investigation Of Kinase Conformational Dynamics And Analytes Detection With Protein Nanopore, Fanjun Li

Doctoral Dissertations

Protein nanopores are pore-forming proteins which have been developed as single-molecule biosensors. Due to the high sensitivity, selectivity, label-free and real-time detection methodology, protein nanopores have been used for a wide variety of applications. In this dissertation, we use ClyA nanopore to investigate kinase conformational dynamics and develop a kinase/nanopore system for the specific detection of kinase allosteric inhibitors. Besides, we engineer OmpG nanopore to be a sensor for nucleic acid detection. Protein kinases play essential roles in cellular regulation by catalyzing the phosphorylation of target proteins and are promising drug targets. The conformational dynamics are critical for kinase functions. …
