Protein Modification for Phosphorylation Research


Creative BioMart offers comprehensive and high-quality protein modification services to accelerate kinase/phosphatase biology research and pharmaceutical development. Our services are tailored for each project to meet specific requirements.


Protein modification refers to any change in the chemical composition of proteins. Co- and post-translational protein modifications are often responsible for the vast biodiversity in nature. These modifications play key roles in various important cellular processes, including differentiation, migration, signaling, and trafficking. Consequently, modifying proteins in a highly efficient and controlled manner would provide an invaluable tool for the study of their precise function and the interrogation and intervention of biological systems both in vitro and in vivo. The complementary use of both genetic and chemical methods offers great possibilities for the preparation of almost unlimited protein constructs with either natural or non-natural/modified residues.

Phosphorylation is one of the most common post-translational modifications. Dephosphorylation is the reverse reaction of phosphorylation. Kinases and phosphatases that responsible for the transfer of phosphate work in a balanced manner to regulate the function of proteins involved in a variety of important cellular functions. The diversity of kinases and phosphatases, multi-site phosphorylation, and the overlap of phosphorylation sites lead to diverse and complex patterns of protein phosphorylation. Kinase/phosphatase biology is extremely complex and challenging to study.
