DPP4 is a cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. It regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones. It removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini with proline as the penultimate residue. It is ubiquitously expressed in epithelial and endothelial cells and plays a role in the migration and invasion of human endothelial cells in collagenous matrices. ADA-DPP4 interaction on the cell surface regulates lymphocyte-epithelial cell adhesion. Dipeptidyl peptidase activity of this protein is inhibited by the binding of Simpson-Golabi-Behmel syndrome causative glypican-3.
