The MAPK pathway (Mitogen-Activated Protein Kinase) is a critical signaling cascade that transmits extracellular signals to the cell's interior, influencing various cellular processes such as proliferation, differentiation, and survival. It comprises several key proteins, including ERK (Extracellular Signal-Regulated Kinase), JNK (c-Jun N-terminal Kinase), and p38 MAPK.
