Kinase activity

Kinase activity involves enzymes called kinases that transfer a phosphate group from a molecule like ATP to a specific target protein. This process, called phosphorylation, acts as a regulatory switch, changing the target protein's activity, location, or interactions. Kinases play essential roles in controlling various cell functions, including growth, division, and response to signals. Proper kinase activity is vital for maintaining healthy cell behavior, whereas abnormal activity can lead to issues like cancer or other diseases. In essence, kinases are vital regulators that modulate protein functions to ensure cells operate correctly.
