discusses the latest information on protein kinases and how they modify other proteins by chemically adding phosphate groups to them. New chapters in this release include Transport Proteins and AMPs: Implications in Human Disease, Protein kinase CK2 inhibition as a pharmacological strategy, Emerging role of Protein kinase in diabetes mellitus: From Mechanism to therapy, Dual Roles of ATP-binding site in Protein Kinases: Orthosteric inhibition and Allosteric Regulation, Pseudokinases in drug discovery and development: progress, challenges and future prospects, Comparison of knowledge-based vs. combinatorial peptide library approaches for the identification of protein kinase substrates, and more.
