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 active GTP-bound and inactive
CC       GDP-bound states. In their active state, drive transport of vesicular
CC       carriers from donor organelles to acceptor organelles to regulate the
CC       membrane traffic that maintains organelle identity and morphology.
CC       Required for protein transport from the endoplasmic reticulum to the
CC       Golgi complex. Regulates the compacted morphology of the Golgi.
CC       {ECO:0000250|UniProtKB:P61019}.
