MAPK (Mitogen-Activated Protein Kinases)

MAPK (Mitogen-Activated Protein Kinases) are a family of enzymes that play a key role in transmitting signals from the surface of a cell to its interior. When a cell detects certain signals—like growth factors or stress—MAPKs are activated, triggering a chain reaction that influences critical functions such as cell growth, division, and survival. They act as messengers, helping cells respond appropriately to their environment. Disruptions in MAPK pathways are linked to diseases like cancer, making them important targets for medical research and drug development.
