function:Sodium-, chloride, pH-independent high affinity transport of large neutral amino acids.,PTM:Glycosylated.,similarity:Belongs to the SLC43A transporter (TC 2.A.1.44) family.,tissue specificity:Detected in several tissues with, higher expression in placenta, kidney and peripheral blood leukocytes. In the kidney is detected in epithelial cells of the distal tubule and collecting duct. In the intestin is expressed mainly in crypt cells of the intestinal microvilli ans epithelial cells in the base of the villus.,
