PHT1, also known as peptide transporter 4, PTR4, hPHT1 or solute carrier family 15 member 4, belongs to a family of peptide transporter proteins known as the Proton-coupled Oligopeptide Transporter (POT) family or the Peptide Transporter (PTR) family. The POT family members are found in mammals, plants, fungi and yeast, and they utilize a proton-dependent mechanism to transport di- and tripeptide-based substrates across the cell membrane. Because peptides are generally hydrophilic and difficult to transport across membrane barriers, insights from the transport pathways of the POT proteins have been used in clinical applications for treatment of many disorders including cancer and hypertension. Localized to the cell membrane, POT proteins contain 12 predicted transmembrane å-helical spans, with a majority of the proteins having intracellular N- and C- termini. PHT1, a 577 amino acid protein, is highly expressed in skeletal muscle and is expressed in low levels throughout the gastrointestinal system, heart, colon and brain. Two isoforms of PHT1 have been identified.
