. "The human SLC15 gene family encode four proton-coupled oligopeptide transporters; PEPT1 (SLC15A1), PEPT2 (SLC15A2), PHT2 (SLC15A3) and PHT1 (SLC15A4). These cotransporters are part of the Proton-coupled Oligopeptide Transporter (POT) superfamily (also called Peptide Transporter (PTR) family) (Daniel H and Kottra G, 2004)."^^ .
