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.
