CC   -!- FUNCTION: Protein transport. Probably involved in vesicular traffic (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Lipid-anchor
CC       {ECO:0000305}; Cytoplasmic side {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Its expression is weak in stems, higher in roots,
CC       leaves and coleoptiles, but highest in flowers.
CC   -!- SIMILARITY: Belongs to the small GTPase superfamily. Rab family.
CC       {ECO:0000305}.
