The slow intrinsic rate of GTP hydrolysis on Ras is stimulated by GTPase-activating proteins (GAPs), such as p120GAP and neurofibromin, while Ras activation requires guanine nucleotide exchange factors (GEFs) that stimulate the dissociation and exchange of bound GDP for GTP on Ras in response ...
His work also offers some clues into the way transforming viruses might activate normal cellular genes to true oncogenes. . 1986 Nature Publishing Companydoi:10.1038/nbt0186-9aBialyHarveyNature Biotechnology

Activation of RAS is crucial in driving cellular outcomes including proliferation, differentiation, migration and apoptosis via the MAPK pathway. This is initiated on recruitment of Grb2, as part of a Grb2-Sos complex, to an up-regulated receptor tyrosin
Finally, we show that the formation of the ezrin-dependent complex is necessary to enhance the catalytic activity of SOS and thereby Ras activation. Taking these findings together, we propose that the ERM proteins are novel scaffolds at the level of SOS activity control, which is relevant for ...
Activation of RAS/ERK signaling pathway, depletion of retinoid, and phosphorylation of retinoid X receptor alpha (RXRα) are frequent events found in liver tumors and thought to play important roles in hepatic tumorigenesis. However, the relationships among them still remained to be elucidated. By ...
(Cat.#23225; ThermoFisher Scientific, Waltham, US). 50 µg total protein was loaded per column of the active RAS detection kit for Western blot (WB). In the RAS activation assay kit for ELISA (Cat.#17-497; EMD Millipore, Burlington, US), 12 µg total protein was used at ...
