Background: DPPII/QPP/DPP7
Dipeptidyl-peptidase II (DPPII) is identical to quiescent cell proline dipeptidase (QPP) and dipeptidylpeptidase 7 (DPP7) (1, 2). It shares some substrate and cleavage specificity with DPPIV/CD26, DPP8, DPP9 and seprase/FAP (fibroblast activation protein), members of the S09 family of serine proteases. As prolyl proteases that cleave proteins and peptides after proline residues, these enzymes have a high potential for drug discovery (3, 4). However, DPP7 is not a member of the S09 family, but a member of the S28 family that also includes lysosomal Pro-X carboxypeptidase/prolylcarboxypeptidase/PRCP and thymus-specific serine peptidase/PRSS16 (2). The mouse DPP7 precursor consists of a signal peptide (amino acids (aa) 1-33) and a mature chain (aa 34-506). The purified recombinant mouse DPP7 is active against Lys-Pro-AMC and Lys-Ala-AMC. Its activity against Lys-Pro-AMC is approximately 10-fold of that against Lys-Ala-AMC under otherwise identical conditions.
