Recombinant antibodies to the small GTPase Rab6 as conformation sensors.

Abstract excerpt

Here we report an approach, based on antibody phage display, to generate molecular conformation sensors. Recombinant antibodies specific to the guanosine triphosphate (GTP)-bound conformation of the small guanosine triphosphatase (GTPase) Rab6, a regulator of membrane traffic, were generated and used to locate Rab6.GTP in fixed cells, and, after green fluorescent protein (GFP) tagging and intracellular...
