Background
Protein phosphorylation is the most common and well-studied post translational modification (PTM). It is estimated that about 30% of the proteome is affected by phorphorylation. The phosphoryl group from ATP is transferred to the amino acid side chain by a kinase and removed by a phosphatase. Kinases participate in elaborate phosphorylation cascades by acting on a number of different substrates and undergoing mutual phosphorylation and activation among different types of kinases. Although kinases have been shown to be involved in signal transduction and other complex regulatory networks, our global understanding of protein phosphorylation has until recently been extremely limited.
Phosphorylation plays a key role in both homeostasis and disease by regulating protein function, altering its structural conformation, and modulating the nature and strength of protein-protein interactions. Phosphorylation at different residues can lead to different consequences. Because of this, quality tools for assessing kinase activity and protein phosphorylation are essential. So far, each technique that has been developed performs well in different applications. However, how to choose the method that is best suited for the experimental design is an issue worthy of attention, which often depends on project objectives, expertise, access to instruments, and budget.
