ADP-ribosylation factor-like protein 2 is a protein that in humans is encoded by the ARL2 gene.[5][6][7]


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.[7]


ARL2 has been shown to interact with Protein unc-119 homolog,[8] TBCD[9][10] and PDE6D.[11][12]
