Dipeptidyl Peptidase VII (DPP7), also known as DPP2 or quiescent cell proline dipeptidase, is a post-proline cleaving aminopeptidase that is expressed in quiescent lymphocytes . DPP7 is used to study the regulation of cell quiescence . Like DPP4, DPP7 may be useful in diabetes and vascular disease research .
DPP7 is essential for maintaining lymphocytes and fibroblasts in G(0). The inhibition of DPP7 results in apoptosis, which is mediated by the induction of c-Myc and p53 . DPP7 has strong sequence homology with prolylcarboxypeptidase and is active at both acidic and neutral pH.
