CC   -!- FUNCTION: GDP-dissociation inhibitor preventing the GDP to GTP exchange
CC       of most Rab proteins. By keeping these small GTPases in their inactive
CC       GDP-bound form regulates intracellular membrane trafficking. Negatively
CC       regulates protein transport to the cilium and ciliogenesis through the
CC       inhibition of RAB8A. {ECO:0000250|UniProtKB:P50395}.
CC   -!- SUBUNIT: Interacts with RHOH. Interacts with the GDP-bound forms of
CC       RAB3A, RAB3B, RAB3C, RAB5A, RAB5B, RAB5C, RAB8B, RAB10, RAB12, RAB35,
CC       and RAB43; binds RAB3D to a lesser extent. Interacts with RAB8A (GDP-
CC       bound inactive form); prevents RAB8A activation. Interacts with DZIP1;
CC       negatively regulates the interaction of GDI2 with GDP-bound RAB8A.
CC       {ECO:0000250|UniProtKB:P50395}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Rab GDI family. {ECO:0000305}.
