Probably required for transit of protein from the ER through Golgi compartment. Binds GTP and GDP and possesses intrinsic GTPase activity. Belongs to the small GTPase superfamily. Rab family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: G protein; G protein, monomeric; G protein, monomeric, Rab
Molecular Function: GTPase activity; protein binding
Biological Process: autophagic vacuole formation; autophagy; cell migration; COPII coating of Golgi vesicle; defense response to bacterium; endocytosis; ER to Golgi vesicle-mediated transport; Golgi organization and biogenesis; growth hormone secretion; retrograde vesicle-mediated transport, Golgi to ER; vesicle transport along microtubule; vesicle-mediated transport; virus assembly
