What Does ERK Stand For?

ERK stands for Extracellular Signal Regulated Kinase

ERK, or Extracellular Signal Regulated Kinase, is a core component of the MAPK (Mitogen-Activated Protein Kinase) signaling pathway. It plays a crucial role in transmitting extracellular signals into the cell, influencing various biological processes such as cell proliferation, differentiation, and survival. ERK activation often occurs in response to various growth factors and hormones, making it a key player in cellular responses to external stimuli. Its dysregulation has been implicated in numerous diseases, including cancer, highlighting its significance in both normal physiology and pathological conditions.
