    ..It is likely that frabin associates with the specific actin and membrane structures and activates Cdc42 and Rac in the vicinity of these structures, eventually leading to morphological changes. ..

    ..The FYVE domain and the second PH domain in addition to the DH domain and the first PH domain are necessary for the lamellipodium-like structure formation. We show here these two actions of frabin in the regulation of cell morphology. ..

    ..Because FGD1 has been shown to serve as a GDP/GTP exchange protein for Cdc42 small G protein, it is likely that frabin is a direct linker between Cdc42 and the actin cytoskeleton. ..
