Kinases are enzymes that catalyze the transfer of phosphate groups from high-energy donor molecules, such as ATP, to specific target proteins. This phosphorylation process plays a crucial role in regulating various cellular processes, including cell growth, metabolism, and signal transduction. Dysregulation of kinase activity has been implicated in a wide range of diseases, including cancer, diabetes, and neurodegenerative disorders. As a result, kinases have become an important target for drug development, with several kinase inhibitors currently being used in the treatment of cancer and other diseases. Research in the field of kinase biology aims to understand the complex signaling networks regulated by these enzymes and develop novel therapies targeting specific kinases.
