function:GTP-binding protein that does not act as an allosteric activator of the cholera toxin catalytic subunit. Component of a regulated secretory pathway involved in Ca(2+)-dependent release of acetylcholine. Regulates formation of new microtubules. Required for normal progress through the cell cycle.,similarity:Belongs to the small GTPase superfamily.,similarity:Belongs to the small GTPase superfamily. Arf family.,subunit:Interacts with SCOC and ELMOD2. The GTP-bound form interacts with ARL2BP.,
Mitochondrion intermembrane space . Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Nucleus. Cytoplasm. The complex formed with ARL2BP, ARL2 and SLC25A6 is expressed in mitochondria. The complex formed with ARL2BP, ARL2 and SLC25A4 is expressed in mitochondria (By similarity). Not detected in the Golgi, nucleus and on the mitotic spindle. Centrosome-associated throughout the cell cycle. Not detected to interphase microtubules. .
