Target Information

In mammalian small intestine, the proton-coupled peptide transporter (PEPT) is responsible for the absorption of small peptides arising from digestion of dietary proteins.
PEPT1, a hydrogen ion/peptide cotransporter, transports dipeptides and tripeptides, but not free amino acids or peptides with more than three amino acid residues.
Its driving force for uphill transport requires proton binding and the presence of an inside-negative membrane potential.
PEPT1 is a 708 amino acid protein containing 12 putative membrane-spanning domains and is expressed in Caco-2 cells.
PEPT1 plays important roles in nutritional and pharmacological therapies.
The mammalian kidney expresses a proton-coupled peptide transporter, PEPT2, responsible for the absorption of small peptides and peptide-like drugs such as beta-lactam antibiotics from the tubular filtrate.
