SLC6A19 mediates the uptake of neutral amino acids across the plasma membrane. Uptake of an amino acid molecule is accompanied by uptake of a sodium ion. The protein is abundant in cells in the small intestine and kidney. Its deficiency is associated with Hartnup disorder, the failure to take up neutral amino acids efficiently from the gut lumen and to reabsorb them in the proximal kidney tubule (Kleta et al. 2004, Seow et al. 2004).
