CC   -!- FUNCTION: The small GTPases Rab are key regulators of intracellular
CC       membrane trafficking, from the formation of transport vesicles to their
CC       fusion with membranes. Rabs cycle between an inactive GDP-bound form
CC       and an active GTP-bound form that is able to recruit to membranes
CC       different set of downstream effectors directly responsible for vesicle
CC       formation, movement, tethering and fusion. Mediates transport of ADRA2A
CC       and ADRA2B from the Golgi to the cell membrane. Plays a role in the
CC       maturation of zymogenic granules and in pepsinogen secretion in the
CC       stomach (By similarity). Plays a role in the secretion of amylase from
CC       acinar granules in the parotid gland. {ECO:0000250,
CC       ECO:0000269|PubMed:10857477, ECO:0000269|PubMed:16076461}.
CC   -!- SUBUNIT: Interacts with ADRA2B. Interacts with RIMS1 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle membrane
CC       {ECO:0000269|PubMed:10857477, ECO:0000269|PubMed:16076461}; Lipid-
CC       anchor {ECO:0000305}; Cytoplasmic side {ECO:0000305}. Golgi apparatus
CC       membrane {ECO:0000250|UniProtKB:Q9ULW5}; Lipid-anchor
CC       {ECO:0000250|UniProtKB:Q9ULW5}; Cytoplasmic side
CC       {ECO:0000250|UniProtKB:Q9ULW5}. Note=Inhibition of S-geranylgeranyl
CC       cysteine formation abolishes membrane location (By similarity).
CC       Localized immediately around secretory granules in the acinar cells of
CC       the parotid gland (PubMed:10857477). Not localized in plasma membranes
CC       (PubMed:10857477). {ECO:0000250, ECO:0000269|PubMed:10857477}.
CC   -!- TISSUE SPECIFICITY: Expressed in pancreas, kidney, brain, submandibular
CC       gland, and lung. {ECO:0000269|PubMed:7864900}.
CC   -!- SIMILARITY: Belongs to the small GTPase superfamily. Rab family.
