SLC7A7 as a heterodimer with SLC3A2 in the plasma membrane mediates the exchange of arginine (L-Arg) for leucine (L-Leu) and a sodium ion (Na+). The physiological concentrations of arginine and leucine are expected to favor arginine export. By the criterion of Northern blotting, SLC7A6 is predominantly expressed in the kidney (Pfeiffer et al. 2000).
