Recent Development of Mass Spectrometry Based Protein Kinase-small Molecule Interaction Analysis

Protein kinases are crucial regulators in many cellular processes, and their aberrance usually lead to serious diseases like cancer. Small molecule inhibitors specifically targeted to protein kinases can provide an efficient solution to the treatment of these diseases. Thus, it is particularly important to elucidate the mechanisms of protein kinase-small molecule interactions. Mass spectrometry (MS) has been widely applied to the field of protein-small molecule interaction analysis due to its high sensitivity, high accuracy and high throughput. This review summarizes the recent developments of MS-based strategies for investigating protein kinase-small molecule interactions. We also discussed the advantages and disadvantages of these MS-based methods. These MS-based strategies are helpful to study the protein kinase-small molecule interactions at molecular level, which can promote the development of new targeted drugs.
