ADP-ribosylation factor-like protein 2 is a protein that in humans is encoded by the ARL2 gene.[1][2][3]


The ADP-ribosylation factor (ARF) genes are small GTP-binding proteins of the RAS superfamily. ARL2 is a member of a functionally distinct group of ARF-like genes.[3]


ARL2 has been shown to interact with Protein unc-119 homolog,[4] TBCD[5][6] and PDE6D.[7][8]
