Ras Signaling

Pathway The Ras Signaling Pathway is an important signal transduction pathway that is involved in cell growth, proliferation, differentiation and survival. It is activated by extracellular growth factors, such as epidermal growth factor and fibroblast growth factor, which bind to specific receptors on the cell's surface. In response to the growth factor, signals are sent to the nucleus, where specific pathways are activated, leading to cell growth. This pathway is vital in the control of metabolic activities and cell growth. Mutations in the Ras pathway can lead to diseases such as cancer, making it an important target for drug development and cancer therapies.
