Extracellular Signal-Regulated Kinases (ERKs)

Extracellular Signal-Regulated Kinases (ERKs) are enzymes that play a key role in transmitting signals from the surface of a cell to its interior. These signals often originate from outside the cell and help regulate important functions such as growth, division, and survival. When a signal is received, ERKs are activated through a series of steps, then move into the cell nucleus to influence gene activity. This process is essential for normal development and responding to environmental changes but can also contribute to diseases like cancer if the signaling becomes abnormal.
