Radium 181-184 RAS p21 protein activator 1 Homo sapiens 28-35 9553053-3 1998 This study demonstrates that the catalytic domain of p120 GTPase-activating protein (GAP), a well known Ras GAP, is able to interact physically with Rab5 and stimulate its GTPase activity. Radium 104-107 RAS p21 protein activator 1 Homo sapiens 53-57 9235929-4 1997 The affinities of Gap1(m) and p120GAP to the substrates determined by competitive inhibition by using Ha-Ras.GTPgammaS (guanosine 5"-O-(3-thiotriphosphate)) or R-Ras.GTPgammaS as a competitor agreed well with the substrate specificities of these GTPase-activating proteins. Radium 105-108 RAS p21 protein activator 1 Homo sapiens 30-37 25663768-10 2015 In addition, pre-miR-21-LV or siRASA1 (down-regulation of RASA1) cells showed higher cell proliferation, reduced apoptosis, increased expression of RAS-GTP, p-AKT, Raf-1, KRAS, and p-ERK1/2, and higher invasion and tumor formation ability, compared with control, anti-miR-21-LV or pcDNA3.1-RASA1 (up-regulation of RASA1) cells (P < 0.05). Radium 32-35 RAS p21 protein activator 1 Homo sapiens 58-63 25663768-10 2015 In addition, pre-miR-21-LV or siRASA1 (down-regulation of RASA1) cells showed higher cell proliferation, reduced apoptosis, increased expression of RAS-GTP, p-AKT, Raf-1, KRAS, and p-ERK1/2, and higher invasion and tumor formation ability, compared with control, anti-miR-21-LV or pcDNA3.1-RASA1 (up-regulation of RASA1) cells (P < 0.05). Radium 32-35 RAS p21 protein activator 1 Homo sapiens 58-63 19022332-1 2009 p120-RasGAP (Ras GTPase activating protein) plays a key role in the regulation of Ras-GTP bound by promoting GTP hydrolysis via its C-terminal catalytic domain.
