Merck, SRP6056, Dipeptidylpeptidase human

General description
DPP4 is a serine exopeptidase and complex enzyme that is expressed on the surface of most cell types as an intrinsic membrane glycoprotein that cleaves X-proline dipeptides from the N-terminus of polypeptides and plays a role in t-cell activation. DPP4 is associated with intracellular signal transduction, apoptosis and involved in tumor biology. There are at least 63 substrates which can bind specifically to DPP4 enzyme including growth factors, chemokines, neuro peptides. Furthermore, DPP4 plays a major role in glucose metabolism by cleaving incretins such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). DPP4 Human Recombinant is a single, glycosylated polypeptide chain containing 746 amino acids (aa 39-766) with a C-terminal His-tag and is purified using conventional chromatography techniques.
