RAB GTPases interact with specific effector molecules in a spatiotemporally regulated manner to induce various downstream reactions. To clarify the overall picture of RAB GTPase functions, it is important to elucidate the cellular locale where RAB and its effectors interact. Here, we applied a bimolecular fluorescence complementation (BiFC) assay to analyze where RAB GTPase interacted with effectors in endosomal trafficking.
