WebMar 15, 2008 · To test whether FRET can detect GEF and GAP activity, Arf6–CyPET and YPET–GGA3 were coexpressed with ACAP1, a GAP for Arf6, or with ARNO, an Arf6 GEF. FRET images were recorded, and then the cells were fixed with formaldehyde and stained for the epitope-tagged GAP or GEF proteins to confirm expression in the same cells. WebTo mediate the process of shuttling between the active and inactive forms, GTPases need the help of two families of proteins: GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs). GEFs replace the GDP bound to inactive GTPase with GTP, making the enzyme active and transducing a wide variety of cellular signals.
