PepT1, which is a member of the proton oligopeptide transporter (POT) superfamily, is well known to transport di/tripeptides. Our group and others have shown that PepT1 is highly expressed in epithelial cells of the small intestine, but present at low or undetectable levels in such cells of the normal large intestine (1-8). We previously showed that the expression and transport activities of PepT1 contribute to colitis and colitis associated cancer (5, 9). More recently, we reported that the fun...
