Descrizione generale
Dipeptidyl Peptidase IV (DPP4) is mapped to human chromosome 2q24.2. It comprises the N-glycosylation sites located in the β-propeller domain.
Applicazioni
Dipeptidyl Peptidase IV human has been used in DPP-IV inhibitory activity assay of quinoa protein concentrate digest.
Human dipeptidyl peptidase IV has been used in a study to assess the interactive hemodynamic effects of its inhibition as well as the angiotensin-converting enzyme inhibition. Human dipeptidyl peptidase IV has also been used in a study to identify and characterize the 100 kDa High Molecular Weight Hymenoptera Venom Allergens Api m 5 and Ves v 3.
Azioni biochim/fisiol
Dipeptidyl Peptidase IV (DPP4) mediates the activation of T-cells. It is also a potential biomarker for lymphoma, thyroid, prostate and colon cancer.
Native DPPIV is a ubiquitous type II transmembrane glycoprotein and a serine protease of the S9 prolyl-oligopeptidase family. In vivo, it is synthesized with a signal peptide, which functions as the membrane anchoring domain. There is an 88% sequence homology between the human and porcine kidney enzymes. Both exist as homodimers with a subunit molecular weight of ~30 kDa. The high mannose 100 kDa DPPIV precursor is processed in the Golgi to yield a 124 kDa heavily N-and O-linked mature glycoprotein. It is then sorted to the apical membrane through the concerted action of both N- and O-linked glycans and its association with lipid microdomains. The porcine enzyme contains 18.3% carbohydrates, which the glycan composition is 0.9% fucose, 3.4% mannose, 5.1% galactose, 8.2% glucosamine, and 0.7% sialic acid. DPPIV is highly expressed on endothelial cells, epithelial cells, and lymphocytes. It is also present in plasma in its soluble form.

Dipeptidyl peptidase-IV inhibitors improve glucose homeostasis in type 2 diabetics by inhibiting degradation of the incretin hormones. Dipeptidyl peptidase-IV inhibition also prevents the breakdown of the vasoconstrictor neuropeptide Y and, when angiotensin-converting enzyme (ACE) is inhibited, substance P. This study
