ARL1

ARL1

A gene on chromosome 12q23.2 that encodes a GTP-binding protein belonging to the ARL (ADP-ribosylation) factor-like family of proteins, which are structurally similar to ADP-ribosylation factors (ARFs), which activate cholera toxin ADP-ribosyltransferase activity, regulate intracellular vesicular membrane trafficking and stimulate a phospholipase D isoform.
