||GTP-binding protein that has very low efficiency as allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. Can activate phospholipase D with very low efficiency. Important for normal function of the Golgi apparatus.
||Golgi apparatus membrane; Peripheral membrane protein; Cytoplasmic side.
||Detected in heart, liver, lung and liver (at protein level). Detected in fetal heart, lung, liver and kidney. Detected in adult heart, placenta, lung, liver, skeletal muscle, kidney and pancreas.
||The GTP-bound form interacts with GOLGA1. The GTP-bound form interacts with GOLGA4 and RGPD8. The GTP-bound form directly interacts with ARFIP2; this interaction leads to a > 4-fold increase in the amount of bound GTP at steady state level. Binds to SCOC, preferentially in its GTP-bound form. May interact with UNC119.
||Belongs to the small GTPase superfamily. Arf family.
