Sodium-independent transporter that mediates the uptake of aromatic acids. Can function as a net efflux pathway for aromatic amino acids in the basosolateral epithelial cells (By similarity). In the epithelial cells is detected in the basolateral membrane but not in the apical membrane. Strongly expressed in intestine, placenta and liver. In small intestine is detected in the basolateral membrane (at protein level). Not N-glycosylated. Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.
