WebThese proteins oscillate between their GTP- and GDP-bound states via regulated cycles of GTP hydrolysis and exchange of GDP for GTP. The exchange of GDP for GTP is accelerated by the GDP/GTP Exchange Factor (GEF), while hydrolase activity of the GTPase is stimulated by the GTPase-Activating Protein (GAP).
WebThe SOS promotes the GDP exchange for GTP on the RAS, however, it does not promote the GDP dissociation on RAS. Continuous phosphorylation of RAS would not lead to the accumulation of the active form of RAS. RAS activity is regulated by GTP binding and hydrolysis, not phosphorylation.
