Function
CD26 cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. Its binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. Its interaction with ADA also regulates lymphocyte-epithelial cell adhesion. In association with FAP is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM. May be involved in the promotion of lymphatic endothelial cells adhesion, migration and tube formation. When overexpressed, enhanced cell proliferation, a process inhibited by GPC3. Also acts as a serine exopeptidase with a dipeptidyl peptidase activity that regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones such as brain natriuretic peptide 32. Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline; (Microbial infection) Acts as a receptor for human coronavirus MERS-CoV-2[1][2][3][4][5][6][7][8][9][10][11].

Expression
Tissue_specificity:This protein is specifically expressed in lymphatic vessels, but not in the blood vessels of the skin, small intestine, esophagus, ovary, breast, and prostate. It was not detected (protein level) in the lymphatic vessels of the lungs, kidneys, uterus, liver, and stomach. It is expressed in both poorly differentiated crypt cells and mature villi cells of the small intestine. Expression levels are extremely low in the colon.
Induction:Up-regulated by IL12/interleukin-12 on activated T-cells. IL12-activated cells expressed enhanced levels of DPP4 but not mRNAs. Down-regulated by TNF. Up-regulated in migratory endothelial cells and in the invasive endothelial cells in tumors. Induced by hypoxia (PubMed:16670267) -
Subunit
Monomer. Homodimer (PubMed:12483204, PubMed:12646248, PubMed:12832764, PubMed:12906826, PubMed:15448155, PubMed:17287217). Heterodimer with Seprase (FAP) (PubMed:16651416). Requires homodimerization for optimal dipeptidyl peptidase activity and T-cell costimulation. Found in a membrane raft complex, at least composed of BCL10, CARD11, DPP4 and IKBKB (PubMed:17287217). Associates with collagen (PubMed:8526932). Interacts with PTPRC; the interaction is enhanced in an interleukin-12-dependent manner in activated lymphocytes (PubMed:12676959). Interacts (via extracellular domain) with ADA; does not inhibit its dipeptidyl peptidase activity (PubMed:10951221, PubMed:14691230, PubMed:15016824, PubMed:7907293, PubMed:8101391). Interacts with CAV1 (via the N-terminus); the interaction is direct (PubMed:17287217). Interacts (via cytoplasmic tail) with CARD11 (via PDZ domain); its homodimerization is necessary for interaction with CARD11 (PubMed:17287217). Interacts with IGF2R; the interaction is direct (PubMed:10900005). Interacts with GPC3 (PubMed:17549790). Interacts with human coronavirus-EMC spike protein and acts as a receptor for this virus (PubMed:23486063)
