Application
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.
Biochem/physiol Actions
DPPIV has a post-proline dipeptidyl aminopeptidase activity that hydrolyzes N-terminal dipeptides from the unsubstituted N-terminus of peptides with the sequence of X-Pro-Z and X-Ala-Z. Where X is a nonspecific residue at the N terminus and Z cannot be proline or hydroxyproline.
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.
General description
Dipeptidyl Peptidase IV (DPP4) is mapped to human chromosome 2q24.2. It comprises the N-glycosylation sites located in the β-propeller domain.
Other Notes
One unit will hydrolyze 1.0 picomole of Ala-Pro-AMC per minute at pH 7.5 at 25 deg °C

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

With the aim to establish a structure-inhibitory activity relationship of flavonoids against dipeptidyl peptidase-4 (DPP-4) and elucidate the interaction mechanisms between them, a pannel of 70 structurally diverse flavonoids was used to evaluate their inhibitory activities against DPP-4, among which
