WebApr 25, 2024 · The epidermal growth factor receptor/mitogen-activated protein kinase (EGFR/MAPK) signaling pathway is a conserved receptor tyrosine kinase pathway that regulates many aspects of development including cell survival, growth, proliferation, and differentiation (Wee and Wang, 2024).

Finally, MAPK can activate a transcription factor, such as Myc. This process is described in more detail below. Ras activation. Receptor-linked tyrosine kinases, such as the epidermal growth factor receptor (EGFR), are activated by extracellular ligands, such as the epidermal growth factor (EGF). See more The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell.
