Kinases are enzymes that play a crucial role in the regulation of various cellular processes by catalyzing the transfer of phosphate groups from ATP to target proteins, thereby altering their function, activity, or localization within the cell. They are key components of signal transduction pathways and are involved in diverse physiological functions such as cell growth, proliferation, differentiation, and apoptosis. Dysregulation of kinase activity has been implicated in numerous diseases, including cancer, inflammation, and metabolic disorders, making them important targets for drug development. Kinase inhibitors have shown promise in the treatment of various cancers and other diseases, and ongoing research in this area aims to further understand the role of kinases in cellular signaling and disease progression.
