ARL1

ADP-ribosylation factor-like protein 1 is a is_associated_with::protein that in humans is encoded by the ARL1 is_associated_with::gene.

Function
The protein encoded by this gene belongs to the ARL (ADP-ribosylation factor-like) family of proteins, which are structurally related to ADP-ribosylation factors (ARFs). ARFs, described as activators of cholera toxin (CT) ADP-ribosyltransferase activity, regulate intracellular vesicular membrane trafficking, and stimulate a phospholipase D (PLD) isoform. Although, ARL proteins were initially thought not to activate CT or PLD, later work showed that they are weak stimulators of PLD and CT in a phospholipid dependent manner.

Interactions
ARL1 has been shown to interact with is_associated_with::GOLGA4 and is_associated_with::GOLGA1.
