Our scientific team with extensive knowledge and experience in basic research and drug development can help our customers overcome obstacles and accelerate their success.

Introduction to Phosphoproteins

Phosphorylation is a key reversible post-translational modification that is involved in many essential cellular processes. The discovery and identification of phosphoproteins is critical to understanding the regulatory role played by phosphorylation. Phosphoproteins are usually generated by a reaction catalyzed by kinases. These proteins are part of the signal transduction cascade that amplifies and propagates cellular signals. Phosphoproteins are therefore important tools for elucidating the phosphorylation network and have been developed as biomarkers and potential therapeutics. Since the study of the dynamic phosphorylation process is challenging, comprehensive phosphoprotein and phosphorylation site analysis is necessary. In recent years, several novel experimental strategies have been developed to synthesize phosphoproteins and explore the phosphorylation status from individual proteins to phosphoproteomes. This has largely promoted the exploration of the biological role of phosphorylation and the understanding of the intricate cellular networks, which might reveal potential therapeutic strategies.
