Abstract excerpt
The activation of p21ras by receptor tyrosine kinases involves the translocation of the growth factor receptor bound protein 2-mammalian son of sevenless protein (Grb2-SOS) complex to the plasma membrane where p21ras is localized. Insulin receptors induce p21ras-GTP formation by two possible mechanisms: tyrosine phosphorylation of insulin receptor substrate 1 (IRS1) and its subsequent association with Grb2, or...
