Guanosine Triphosphate 129-132 H3 histone pseudogene 16 Homo sapiens 111-114 1634508-2 1992 rho p21 is a common substrate small G protein for both GDP/GTP exchange proteins. Guanosine Triphosphate 59-62 H3 histone pseudogene 16 Homo sapiens 4-7 1634508-3 1992 We examined here the functional interactions of these GDP/GTP exchange proteins with rho p21 as a substrate. Guanosine Triphosphate 58-61 H3 histone pseudogene 16 Homo sapiens 89-92 1634508-7 1992 Since the content of smg GDS was generally less than that of rho GDI in cells, these results suggest that there is some mechanism to release the inhibitory action of rho GDI and to make rho p21 sensitive to the smg GDS action during the conversion of rhoA p21 from the GDP-bound inactive form to the GTP-bound active form in intact cells.
