ARL2

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

Function

The ADP-ribosylation factor genes are small GTP-binding proteins of the RAS superfamily. ARL2 is a member of a functionally distinct group of ARF-like genes.
In photoreceptors, ARL2 participates in the trafficking of lipidated membrane-associated proteins.
There is an evidence that increased activity of ARL2 protein is strongly correlated with increased mitochondria fusion, while loss of ARL2 activity results in a decreased rate of fusion.
