Description

CD26, also known as DPPIV/DPP4 (dipeptidyl peptidase-4) and ADCP2 (adenosine deaminase complexing protein 2), is a single pass type II transmembrane protein consisting of a short cytoplasmic tail, a transmembrane domain, and a long extracellular domain (ECD). The ECD of CD26 is a serine exopeptidase belonging to the S9B family that cleaves Xaa-proline dipeptides from the N-terminus of polypeptides, such as chemokines, neuropeptides, and peptide hormones such as glucagon. CD26 plays an important role in many biological and pathological processes. CD2 acts as a T cell-activating molecule and serves as a cofactor for entry of HIV in CD4+ cells. CD26 binds adenosine deaminase, the deficiency of which causes severe combined immunodeficiency disease in humans. CD26 exists as a homodimer on the cell surface and the soluble form is also detectable in human serum and other body fluids.   The levels of soluble CD26 may have clinical significance in patients with cancer, liver and kidney diseases, and depression. DPP4 inhibition results in increased blood concentration of the incretin hormones glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP). This causes an increase in glucose-dependent stimulation, resulting in a lowering of blood glucose levels.  Therefore DPP4 inhibitors represent a new pharmacological class of drugs for treating Type 2 diabetes.
