We have developed a novel assay to monitor the active, GTP-bound form of Rap1 based on the differential affinity of Rap1GTP and Rap1GDP for the Rap binding domain of RalGDS ( RBD ).
 ( protein: Rap1GTP, None) , ( protein: RalGDS, None) , ( protein: GTP-bound form, None) , ( protein: RBD, None) , ( protein: Rap1, None) , ( protein: Rap1GDP, None) , ( protein: Rap binding domain, None)
