MAPK pathway

The MAPK pathway is a communication system inside cells that helps them respond to signals like stress, growth factors, or infections. When a signal arrives, it activates a series of proteins in sequence, called kinases, which relay and amplify the message. This ultimately leads to changes in the cell, such as dividing, surviving, or producing specific proteins. The pathway ensures that cells respond appropriately to their environment, and dysfunctions in this system can contribute to diseases like cancer. Overall, the MAPK pathway is essential for normal cell function and adaptation.
