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, monomeric; G protein; G protein, monomeric, Rab
Molecular Function: GTP binding; GTPase activity; protein binding
Biological Process: autophagic vacuole formation; autophagy; cell migration; cellular protein metabolic process; cilium biogenesis; COPII coating of Golgi vesicle; defense response to bacterium; endocytosis; ER to Golgi vesicle-mediated transport; Golgi organization and biogenesis; growth hormone secretion; melanosome transport; mitotic cell cycle; post-translational protein modification; protein amino acid N-linked glycosylation via asparagine; small GTPase mediated signal transduction; vesicle transport along microtubule; vesicle-mediated transport; virus assembly
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
