This is the N-terminal domain of nuclear-export cofactor Arc1p (Arc1p-N). Arc1p-N and GluRS-N are known to be necessary and sufficient for formation of the yeast aaRS complex in vivo and in vitro. They are likely to form a stable complex with each other. Arc1p-N adopts a fold similar to the C-terminal domain of glutathione S-transferase (GST-C).	Domain
