Peptidase CD26

CD26/dipeptidyl peptidase IV (DPPIV) is a multifunctional membrane protein with a key role in T-cell biology and also serves as a marker of aggressive cancers, including T-cell malignancies. Methods: Versican expression was measured by real-time RT-PCR and Western blots. Gene silencing of versican in parental Karpas 299 cells was performed using transduction-ready viral particles.

Recurrence of colorectal cancer (CRC) may arise due to the persistence of drug-resistant and cancer-initiating cells that survive exposure to chemotherapy. Proteins responsible for this recurrence include the chemokine receptor CXCR4, which is known to enable CRC metastasis, as well as the cancer-initiating cell marker and peptidase CD26, which terminates activity of its chemokine CXCL12.

CD26 is an ectoenzyme with dipeptidyl peptidase 4 (DPP4) activity expressed on a variety of cell types. Considering that serum CD26 levels have been previously associated with different cancers, we examined the potential diagnostic value of serum CD26 levels in gastric cancer.

Dipeptidyl peptidase IV (DP IV, CD26) plays an essential role in the activation and proliferation of lymphocytes, which is shown by the immunosuppressive effects of syn-thetic DP IV inhibitors. Similarly, both human immuno-deficiency virus-1 (HIV-1) Tat protein and the N-terminal peptide Tat(1–9) inhibit DP IV activity and T cell prolifer-ation. Therefore, the N-terminal amino acid sequence of HIV-1 Tat is important for the inhibition of DP IV.

Dipeptidyl peptidase IV (DPP IV, CD26, EC 3.4.14.5) serves as a model aimed at elucidating protein sorting signals. We identify here, by MS, sev-eral tyrosine-phosphorylated proteins in a rat liver Golgi⁄endosome (G⁄E) fraction including DPP IV. We show that a pool of DPP IV is tyrosine-phosphorylated.
