Staining of normal human peripheral blood cells with Anti-human DPP4 FITC (upper) and PE (bottom). Appropriate isotype controls were used (open histogram). Cells in the lymphocyte population were used for analysis.
The protein encoded by this gene is identical to adenosine deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic membrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. [provided by RefSeq
