CC   -!- FUNCTION: General Rab protein regulator required for vesicle formation
CC       from the Golgi complex. May control vesicle docking and fusion by
CC       mediating the action of Rab GTPases to the SNARE complexes. In addition
CC       it inhibits the removal of Rab GTPases from the membrane by GDI1.
CC       {ECO:0000250|UniProtKB:O35394}.
CC   -!- SUBUNIT: Homodimer. Interacts with VAMP2 (synaptobrevin-2), prenylated
CC       Rab proteins, GDI1, NDRG1 and PCLO (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:O35394};
CC       Multi-pass membrane protein {ECO:0000255}. Cytoplasm
CC       {ECO:0000250|UniProtKB:O35394}. Golgi apparatus
CC       {ECO:0000250|UniProtKB:O35394}. Cytoplasmic vesicle, secretory vesicle,
CC       synaptic vesicle {ECO:0000250|UniProtKB:O35394}. Note=According to some
CC       authors, it is an integral membrane protein, while others showed that
CC       it is cytoplasmic and membrane-associated to Golgi and synaptic
CC       vesicles. {ECO:0000250|UniProtKB:O35394}.
CC   -!- SIMILARITY: Belongs to the PRA1 family. {ECO:0000305}.
