GTP-Binding Protein Beta Subunits

Membrane translocation of P-Rex1 is mediated by G protein betagamma subunits and phosphoinositide 3-kinase
P-Rex1 is a guanine-nucleotide exchange factor (GEF) for the small GTPase Rac that is directly activated by the betagamma subunits of …

Regulation of P-Rex1 by phosphatidylinositol (3,4,5)-trisphosphate and Gbetagamma subunits
P-Rex1 is a guanine-nucleotide exchange factor (GEF) for the small GTPase Rac. We have investigated here the mechanisms of stimulation …
