Protein phosphorylation is an important cellular regulatory mechanism. A broad range of receptors and enzymes can be activated/deactivated by phosphorylation/dephosphorylation events. Kinases are responsible for protein phosphorylation. They catalyze the transfer of phosphate from a donor ATP molecule to a wide variety of cellular substrates, resulting in the formation of phosphorylated products and ADP. Kinases themselves can also be regulated by other kinases and initiate cascade reactions. Because of their important role in many cellular processes, kinases have been one of the most widely studied enzyme families in biological and medical research. Hyperactive or malfunctioning kinases have also been associated with various diseases such as cancer, diabetes, and cardiovascular diseases, making them important targets for drug discovery.
The rapidly growing interest in kinases research and drug discovery has prompted the development of many different assay technologies to monitor changes in kinase activity. Kinase functional assays focus on detecting kinase activity by directly or indirectly quantifying either the formation of the phosphorylated product or the amount of ATP used or ADP formed. Compared to binding assays and cellular assays, kinase functional assays are the most preferred assay format. The commonly used functional assays include colorimetric assays, bioluminescent assays, fluorescence-based assays, radiometric assays, label-free assays, and mobility shift assays. Understanding different format of kinase functional assays is the first and key step in elucidating kinase signaling and developing successful drugs.

Colorimetric assays have gained great interest due to their inherent advantages, including low cost, simple operation, adaptable sensitivity, quick response, wide linear range, and the possibility of qualitative or semiqualitative identification by the naked eye.
Luminescence-based kinase assays can be used to measure the depletion of ATP. Bioluminescent assays are homogeneous and stable, offering the advantages of sensitivity, broad linearity, and robustness for high-throughput screening (HTS) applications.
Fluorescence offers unmatched sensitivity, stability, and flexibility compared to many other techniques. The diversity of available fluorescent dyes provides virtually unlimited possibilities for assay design. These advantages make fluorescence-based assays one of the easiest and popular methods for kinase activity studies.
Radiometric assays allow direct measurement of the rate of a given kinase reaction to accurately determine and quantify its catalytic activity. This assay format is versatile and compatible with virtually any type of kinase substrates, as long as there is a suitable method to separate radiolabeled ATP and substrate.
Label-free methods have been developed and attracted increasing attention in the development of kinase assays due to their low production cost, pathway-unbiased, fast response, and high sensitivity. These assays provide a new dimension to elucidate kinase biology and facilitate drug discovery.
The ability of mobility shift assays to real-time monitoring the activity and kinetics of kinases, coupled with the fact that this technique allows for accurate quantitation of both substrates and products, makes it a good candidate for kinetic and mechanistic studies of kinases.
