Mitogen-Activated Protein Kinase (MAPK) Signaling Pathway (MAPK pathway)

Target
MAPK pathway
Molecular classification
Signaling pathway, Kinase cascade
01

Overview

The mitogen-activated protein kinase (MAPK) signaling pathway is a highly conserved cascade of protein kinases that transmits extracellular signals to regulate a wide range of essential cellular processes, including proliferation, differentiation, apoptosis, stress responses, and immune defense. It operates through a multi-tiered kinase cascade: MAP3K, MAP2K, and MAPK. Major subfamilies include ERKs, JNKs, and p38. Dysregulation can lead to diseases including cancer or neurological disorders.
