Protein Kinases

Protein kinases are enzymes that play a crucial role in regulating various cellular functions by adding phosphate groups to proteins. This process, called phosphorylation, can activate or deactivate a protein, thereby influencing processes like cell growth, division, and metabolism. By modifying proteins, kinases help cells respond to signals from their environment, ensuring proper functioning and communication within the body. Dysregulation of protein kinases is often linked to diseases, including cancer, making them important targets for therapeutic research.
