How are rtks activated

WebRTKs can activate Ras, a protein that is tethered to the plasma membrane, by causing it to bind GTP. Once activated, Ras can do a variety of things. In this example, it activates … WebRTKs activate Rho via a signaling cascade that includes the following steps: Initially, ligand interaction activates RTKs, which causes the receptor to become autophosphorylated and attract adaptor proteins like Grb2. The small GTPase Ras is activated by Grb2's subsequent binding to the GEF Sos, which promotes the conversion of GDP to GTP.
